(a) Instrumentation. The following instrumentation shall be used, where applicable. (1) A sound level meter which meets the Type 1 requirements of ANSI S1.4-1971, Specification for Sound Level Meters, or a sound level meter may be used with a magnetic tape recorder and/or a graphic level recorder or indicating meter, providing the system meets the requirements of Sec. 205.54-2. (2) A sound level calibrator. The calibrator shall produce a sound pressure level, at the microphone diaphragm, that is known to within an accuracy of <SUP>plus-minus</SUP>0.5 dB. The calibrator shall be checked annually to verify that its output has not changed. (3) An engine-speed tachometer which is accurate within <SUP>plus-minus</SUP>2 percent of meter reading. (4) An anemometer or other device for measurement of ambient wind speed accurate within <SUP>plus-minus</SUP>10 percent. (5) A thermometer for measurement of ambient temperature accurate within <SUP>plus-minus</SUP>1 C. (6) A barometer for measurement of ambient pressure accurate within <SUP>plus-minus</SUP>1 percent. (b)(1) The test site shall be such that the truck radiates sound into a free field over a reflecting plane. This condition may be considered fulfilled if the test site consists of an open space free of large reflecting surfaces, such as parked vehicles, signboards, buildings or hillsides, located within 100 feet (30.4 meters) of either the vehicle path or the microphone. (2) The microphone shall be located 50 feet <SUP>plus-minus</SUP>4 in. (15.2<SUP>plus-minus</SUP>0.1 meter) from the centerline of truck travel and 4 feet <SUP>plus-minus</SUP>4 in. (1.2<SUP>plus-minus</SUP>0.1 meters) above the ground plane. The microphone point is defined as the point of intersection of the vehicle path and the normal to the vehicle path drawn from the microphone. The microphone shall be oriented in a fixed position to minimize the deviation from the flattest system response over the frequency range 100 Hz to 10 kHz for a vehicle traversing from the acceleration point through the end zone. The microphone shall be oriented with respect to the source so that the sound strikes the diaphragm at the angle for which the microphone was calibrated to have the flattest frequency response characteristic over the frequency range 100 Hz to 10 kHz. (3) An acceleration point shall be established on the vehicle path 50 feet (15 m) before the microphone point. (4) An end point shall be established on the vehicle path 100 feet (30 m) from the acceleration point and 50 feet (15 m) from the microphone point. (5) The end zone is the last 40 feet (12 m) of vehicle path prior to the end point. (6) The measurement area shall be the triangular paved (concrete or sealed asphalt) area formed by the acceleration point, the end point, and the microphone location. (7) The reference point on the vehicle, to indicate when the vehicle is at any of the points on the vehicle path, [[Page 101]] shall be the front of the vehicle except as follows: (i) If the horizontal distance from the front of the vehicle to the exhaust outlet is more than 200 inches (5.1 meters), tests shall be run using both the front and rear of the vehicle as reference points. (ii) If the engine is located rearward to the center of the chassis, the rear of the vehicle shall be used as the reference point. (8) The plane containing the vehicle path and the microphone location (plane ABCDE in Figure 1) shall be flat within <SUP>plus-minus</SUP>2 inches (.05 meters). (9) Measurements shall not be made when the road surface is wet, covered with snow, or during precipitation. (10) Bystanders have an appreciable influence on sound level meter readings when they are in the vicinity of the vehicle or microphone; therefore not more than one person, other than the observer reading the meter, shall be within 50 feet (15.2 meters) of the vehicle path or instrument and the person shall be directly behind the observer reading the meter, on a line through the microphone and observer. To minimize the effect of the observer and the container of the sound level meter electronics on the measurements, cable should be used between the microphone and the sound level meter. No observer shall be located within 1 m in any direction of the microphone location. (11) The maximum A-weighted fast response sound level observed at the test site immediately before and after the test shall be at least 10 dB below the regulated level. (12) The road surface within the test site upon which the vehicle travels, and, at a minimum, the measurements area (BCD in figure 205.1) shall be smooth concrete or smooth sealed asphalt, free of extraneous material such as gravel. [GRAPHIC] [TIFF OMITTED] TC01FE92.052 [[Page 102]] (13) Vehicles with diesel engines shall be tested using Number 1D or Number 2D diesel fuel possessing a cetane rating from 42 to 50 inclusive. (14) Vehicles with gasoline engines shall use the grade of gasoline recommended by the manufacturer for use by the purchaser. (15) Vehicles equipped with thermo- statically controlled radiator fans may be tested with the fan not operating. (c) Procedures--(1) Vehicle operation for vehicles with standard transmissions. Full throttle acceleration and closed throttle deceleration tests are to be used. A beginning engine speed and proper gear ratio must be determined for use during measurements. Closed throttle deceleration tests are required only for those vehicles equipped with an engine brake. (i) Select the highest rear axle and/or transmission gear (``highest gear'' is used in the usual sense; it is synonymous to the lowest numerical ratio) and an initial vehicle speed such that at wide-open throttle the vehicle will accelerate from the acceleration point. (a) Starting at no more than two-thirds (66 percent) of maximum rated or of governed engine speed. (b) Reaching maximum rated or governed engine speed within the end zone. (c) Without exceeding 35 mph (56 k/h) before reaching the end point. (1) Should maximum rated or governed rpm be attained before reaching the end zone, decrease the approach rpm in 100 rpm increments until maximum rated or governed rpm is attained within the end zone. (2) Should maximum rated or governed rpm not be attained until beyond the end zone, select the next lower gear until maximum rated or governed rpm is attained within the end zone. (3) Should the lowest gear still result in reaching maximum rated or governed rpm beyond the permissible end zone, unload the vehicle and/or increase the approach rpm in 100 rpm increments until the maximum rated or governed rpm is reached within the end zone. (ii) For the acceleration test, approach the acceleration point using the engine speed and gear ratio selected in paragraph (c)(1) of this section and at the acceleration point rapidly establish wide-open throttle. The vehicle reference shall be as indicated in paragraph (b)(7) of this section. Acceleration shall continue until maximum rated or governed engine speed is reached. (iii) Wheel slip which affects maximum sound level must be avoided. (2) Vehicle operation for vehicles with automatic transmissions. Full throttle acceleration and closed throttle deceleration tests are to be used. Closed throttle deceleration tests are required only for those vehicles equipped with an engine brake. (i) Select the highest gear axle and/or transmission gear (highest gear is used in the usual sense; it is synonymous to the lowest numerical ratio) in which no up or down shifting will occur under any operational conditions of the vehicle during the test run. Also, select an initial vehicle speed such that at wide-open throttle the vehicle will accelerate from the acceleration point. (a) Starting at two-thirds (66 percent) of maximum rated or of governed engine speed. (b) Reaching maximum rated or governed engine speed within the end zone. (c) Without exceeding 35 mph (56 k/h) before reaching the end point. (1) Should maximum rated or governed rpm be attained before reaching the end zone, decrease the approach rpm in 100 rpm increments until maximum rated or governed rpm is attained within the end zone. (2) Should maximum rated or governed rpm not be attained until beyond the end zone, select the next lower gear until maximum rated or governed rpm is attained within the end zone. (3) Should the lowest gear still result in reaching maximum rated or governed rpm beyond the permissible end zone, unload the vehicle and/or increase the approach rpm in 100 rpm increments until the maximum rated or governed rpm is reached within the end zone, notwithstanding that approach engine speed may now exceed two-thirds of maximum rated or of full load governed engine speed. (4) Should the maximum rated or governed rpm still be attained before entering the end zone, and the engine rpm during approach cannot be further lowered, begin acceleration at a point [[Page 103]] 10 feet closer to the beginning of the end zone. The approach rpm to be used is to be that rpm used prior to the moving of the acceleration point 10 feet closer to the beginning of the end zone. (5) Should the maximum rated or governed rpm still be attained before entering the end zone, repeat the instructions in paragraph (c)(2)(i)(c)(4) of this section until maximum rated or governed rpm is attained within the end zone. (ii) For the acceleration test, approach the acceleration point using the engine speed and gear ratio selected in paragraph (c)(2)(i) of this section and at the acceleration point rapidly establish wide-open throttle. The vehicle reference shall be as indicated in paragraph (b)(7) of this section. Acceleration shall continue until maximum rated or governed engine speed is reached. (iii) Wheel slip which affects maximum sound level must be avoided. (3) Measurements. (i) The meter shall be set for ``fast response'' and the A-weighted network. (ii) The meter shall be observed during the period while the vehicle is accelerating or decelerating. The applicable reading shall be the highest sound level obtained for the run. The observer is cautioned to rerun the test if unrelated peaks should occur due to extraneous ambient noises. Readings shall be taken on both sides of the vehicle. (iii) The sound level associated with a side shall be the average of the first two pass-by measurements for that side, if they are within 2 dB(A) of each other. Average of measurements on each side shall be computed separately. If the first two measurements for a given side differ by more than 2 dB(A), two additional measurements shall be made on each side, and the average of the two highest measurements on each side, within 2 dB(A) of each other, shall be taken as the measured vehicle sound level for that side. The reported vehicle sound level shall be the higher of the two averages. (d) General requirements. (1) Measurements shall be made only when wind velocity is below 12 mph (19 km/hr). (2) Proper usage of all test instrumentation is essential to obtain valid measurements. Operating manuals or other literature furnished by the instrument manufacturer shall be referred to for both recommended operation of the instrument and precautions to be observed. Specific items to be adequately considered are: (i) The effects of ambient weather conditions on the performance of the instruments (for example, temperature, humidity, and barometric pressure). (ii) Proper signal levels, terminating impedances, and cable lengths on multi-instrument measurement systems. (iii) Proper acoustical calibration procedure to include the influence of extension cables, etc. Field calibration shall be made immediately before and after each test sequence. Internal calibration means is acceptable for field use, provided that external calibration is accomplished immediately before or after field use. (3)(i) A complete calibration of the instrumentation and external acoustical calibrator over the entire frequency range of interest shall be performed at least annually and as frequently as necessary during the yearly period to insure compliance with the standards cited in American National Standard S1.4-1971 ``Specifications for Sound Level Meters'' for a Type 1 instrument over the frequency range 50 Hz-10,000 Hz. (ii) If calibration devices are utilized which are not independent of ambient pressure (e.g., a piston-phone) corrections must be made for barometric or altimetric changes according to the recommendation of the instrument manufacturer. (4) The truck shall be brought to a temperature within its normal operating temperature range prior to commencement of testing. During testing appropriate caution shall be taken to maintain the engine temperatures within such normal operating range.

Sec. 205.54-2  Sound data acquisition system.

    (a) Systems employing tape recorders and graphic level recorders may 
be established as equivalent to a Type I--ANSI S1.4-1971 sound level 
meter for use in determining compliance with this regulation by meeting 
the requirements of this section (Sec. 205.54-2(b)). This sound data 
acquisition system qualification procedure is based primarily on ANSI 
S6.1-1973.
    (1) Performance requirements--(i) System frequency response. It is 
required that the overall steady-state frequency response of the data 
acquisition system shall be within the tolerances prescribed in Table 
205.1 when measured in accordance with section (2). The tolerances in 
Table 205.1 are applicable to either flat or A-weighted response. (See 
paragraph (a)(3)(iii) of this section.)
    (ii) Detector response. To ensure that a (true) rms indication is 
provided, the difference between the level indicated for a 1000 Hz 
sinusoidal signal equivalent to a sound level of 86 dB (rms) and the 
level indicated for an octave band of random noise of equal energy as 
the sinusoidal signal centered at 1000 Hz shall be no greater than 0.5 
dB. A true rms voltmeter shall be used to determine equivalence of two 
input signals.
    (iii) Indicating meter. If an indicating meter is used to obtain 
sound levels or band pressure levels, it must meet the requirements of 
paragraphs (a)(1)(ii) and (vi)(B) of this section and the following.

------------------------------------------------------------------------

    (A) The scale shall be graduated in 1 dB steps.
    (B) No scale indication shall be more than 0.2 dB different from the 
true value of the signal when an input signal equivalent to 86 dB sound 
level indicates correctly.
    (C) Maximum indication for an input signal of 1000 Hz tone burst of 
0.2 sec duration shall be within the range of -2 to 0 dB with respect to 
the steady-state indication for a 1000 Hz tone equivalent to 86 dB sound 
level.
    (iv) Microphone. If microphone is used which has not been provided 
as a component of a precision sound level meter, it must be determined 
to meet the microphone characteristics described in IEC Publication 179, 
Precision Sound Level Meters.
    (v) Magnetic tape recorders. No requirements are described in this 
document pertaining to tape recorders, except for frequency response. 
Generally, recorders of adequate quality to provide the frequency 
response performance required will also meet other minimum requirements 
for distortion, signal-to-noise ratio, etc.
    (vi) Graphic level recorder dynamic response. When using a graphic 
level recorder, it is necessary to select pen response settings such 
that the readings obtained are statistically equivalent to those 
obtained by directly reading a meter which meets the ``fast'' dynamic 
requirement of a precision sound level meter indicating meter system for 
the range of vehicles to be tested. To ensure statistical equivalence, 
at least 30 comparative observations of real test data shall be made and 
the average of the absolute value of the differences observed shall be 
less than 0.5 dB. The settings described in this paragraph

[[Page 105]]

likely assure appropriate dynamic response; however, different settings 
may be selected on the basis of the above requirement.
    (A) Use a pen writing speed of nominally 60-100 dB/sec. If 
adjustable, low frequency response should be limited to about 20 Hz.
    (B) Indicated overshoot for a suddenly applied 1000 Hz sinusoidal 
signal equivalent to 86 dB sound level shall be no more than 1.1 dB and 
no less than 0.1 dB.
    (2) Frequency response qualification procedure. (i) Typical noise 
measurement and analysis configurations are shown in Figures 205.2 
through 205.4. The qualification procedure described herein duplicates 
these configurations, but with the microphone replaced by an electronic 
sinewave oscillator. Caution should be exercised when connecting an 
oscillator to the input of a sound level meter to ensure, perhaps by 
using a resistive voltage divider network, that the input is not 
overloaded (see Sec. 205.54-2(a)(2)(ii)).

[[Page 106]]

[GRAPHIC] [TIFF OMITTED] TC01FE92.053



[[Page 107]]

    (ii) Calibrate the oscillator to be used by measuring its output 
relative to the voltage which is equivalent to 86 dB sound level at each 
of the 27 frequencies listed in Table 205.1 using an electronic 
voltmeter of known calibration. Record the result in voltage level in dB 
re voltage corresponding to 86 dB sound level at 1000 Hz. This will 
describe the frequency response characteristics of the oscillator.
    (iii) If a graphic level recorder is to be used, connect it to the 
oscillator output. If the oscillator and graphic level recorder can be 
synchronized, slowly sweep the frequency over the range of 31.5 to 
12,500 Hz, recording the oscillator output. If they cannot be 
synchronized, record oscillator output for signals at the 27 frequencies 
given in Table 205.1. The differences between the combined response thus 
obtained and the oscillator response obtained previously will describe 
the frequency response of the graphic level recorder.
    (iv) If visual observation of an indicating meter is to be used for 
obtaining data, the oscillator should be connected to the indicating 
meter input (such as the microphone input of a sound level meter) and 
the meter reading observed for a fixed oscillator output voltage setting 
for signals at the 27 frequencies given in Table 205.1.
    (v) To check a tape recorder, connect the instruments as shown in 
Figure 205.4. Using a 1000 Hz tone, adjust the oscillator output level 
to obtain a reading 15 dB below maximum record level. If the 
synchronized oscillator/graphic level recorder system is to be used for 
analysis, record an oscillator sweep over the range of 31.5 to 12,500 
Hz, using an appropriate tape recorder input attenuator setting. 
Alternatively, tape-record frequency tones at the 27 frequencies given 
in Table 205.1. Replay the tape recordings using the setup shown in 
Figure 205.3. Record the data on a graphic level recorder or through 
visual observation of the indicating meter. Subtract the oscillator 
frequency response in paragraph (b)(2) of this section from the response 
obtained through the record-playback sequence to obtain the record/
reproduce frequency response of the system except for the microphone.
    (vi) To obtain the overall system frequency response, add the 
manufacturer's microphone calibration data to the response just 
obtained. This may be the frequency response for the specific microphone 
to be used, including calibration tolerances. Alternatively, use the 
manufacturer's ``typical'' microphone response plus and minus the 
maximum deviation expected from ``typical'' including calibration 
tolerances. Use the microphone response curve which corresponds to the 
manner in which it is used in the field. It may be required to add a 
correction to the response curves provided to obtain field response; 
refer to the manufacturer's manual.
    (vii) Adjustment or repair of equipment may be required to obtain 
response within the requirements of paragraph (a) of this section. After 
any adjustments, the system shall be requalified according to paragraph 
(b) of this section.
    (3) General comments. (i) Calibrate tape recorders using the brand 
and type of magnetic tape used for actual data acquisition. Differences 
in tape can cause an appreciable variation in the recorder/reproduce 
frequency response characteristics of tape recorder.
    (ii) It shall be ensured that the instrumentation used will perform 
within specifications and applicable tolerances over the temperature, 
humidity, and other environmental variation ranges which may be 
encountered in vehicle noise measurement works.
    (iii) Qualification tests shall be performed using equipment 
(including cables) and recording and playback techniques identical with 
those used while recording vehicle noise. For example, if weighted sound 
level data are normally recorded use similar weighting and apply the 
tolerances of Table 205.1 to the weighting curve for comparison with 
record-playback curves. Precautions should also be taken to ensure that 
source and load impedances are appropriate to the device being tested. 
Other data acquisition systems may use any combination of microphones, 
sound level meters, amplifiers, tape recorders, graphic level recorders, 
or indicating meters. The same approach to qualifying such a system 
shall be taken as described in this document for the

[[Page 108]]

systems depicted in Figures 205.2, 205.3 and 205.4.
    (b) Systems other than those specified in Secs. 205.54-1(a) and 
205.54-2(a) may be used for establishing compliance with this 
regulation. In each case the system must yield sound levels which are 
equivalent to those produced by a sound level meter Type 1 ANSI S1.4-
1971. The manufacturer bears the burden of demonstrating such 
equivalence.

Sec. 205.55-2  Compliance with standards.

    (a)(1) Prior to distribution in commerce of vehicles of a specific 
configuration, the first manufactures of such vehicles must verify such 
configurations in accordance with the requirements of this subpart.
    (2) [Reserved]
    (3) At any time following receipt of notice under this section with 
respect to a configuration, the Administrator may require that the 
manufacturer ship test vehicles to the EPA test facility in order for 
the Administrator to perform the tests required for production 
verification.
    (b) The requirements for purposes of testing by the Administrator 
and selective enforcement auditing with regard to each vehicle 
configuration consist of:
    (1) Testing in accordance with Sec. 205.54 of a vehicle selected in 
accordance with Sec. 205.57-2, and
    (2) Compliance of the test vehicle with the applicable standard when 
tested in accordance with Sec. 205.54.
    (c)(1) In lieu of testing vehicles of every configuration as 
described in paragraph (b) of this section, the manufacturer may elect 
to verify the configuration based on representative testing, the 
requirements of which consist of:
    (i) Grouping configurations into a category where each category will 
be determined by a separate combination of at least the following 
parameters (a manufacturer may use more parameters):
    (a) Engine type.
    (1) Gasoline--two stroke cycle.
    (2) Gasoline--four stroke cycle.
    (3) Diesel--two stroke cycle.
    (4) Diesel--four stroke cycle.
    (5) Rotary--wankel.
    (6) Turbine.
    (7) Other.
    (b) Engine manufacturer.
    (c) Engine displacement.
    (d) Engine configuration (e.g., L-6, V-8, etc.).
    (e) Series (i.e., cab design) including but not limited to 
conventional, cab over engine, and cab forward.
    (ii) Identifying the configuration within each category which emits 
the highest sound pressure level (dBA) based on his best technical 
judgment and/or emission test data;
    (iii) Testing in accordance with Sec. 205.54 of a vehicle selected 
in accordance with Sec. 205.57-2 which must be a vehicle of the 
configuration which is identified pursuant to paragraph (c)(1)(ii) of 
this section as having the highest sound pressure level (estimated or 
actual) within the category; and

[[Page 109]]

    (iv) Compliance of the test vehicle with applicable standards when 
tested in accordance with Sec. 205.54.
    (2) Where the requirements of paragraph (c)(1) are complied with, 
all those configurations contained within a category are considered 
represented by the tested vehicle.
    (3) Where the manufacturer tests a vehicle configuration which has 
not been determined as having the highest sound pressure level of a 
category, but all other requirements of paragraph (c)(1) of this section 
are complied with all those configurations contained with that category 
which are determined to have sound pressure levels no greater than the 
tested vehicle are considered to be represented by the tested vehicle, 
however, a manufacturer must for purposes of Testing by the 
Administrator and Selective Enforcement Auditing verify according to the 
requirements of paragraphs (b)(1) and/or (c)(1) of this section any 
configurations in the subject category which have a higher sound 
pressure level than the vehicle configuration tested.
    (d) [Reserved]
    (e) The manufacturer may, at his option, proceed with any of the 
following alternatives with respect to any vehicle determined not in 
compliance with applicable standards.
    (1) In the case of representative testing a new test vehicle from 
another configuration must be selected according to the requirements of 
paragraph (c) of this section, in order to verify the configurations 
represented by the non-compliant vehicle.
    (2) Modify the test vehicle and demonstrate by testing that it meets 
applicable standards. The manufacturer must modify all production 
vehicles of the same configuration in the same manner as the test 
vehicle before distribution into commerce.

Sec. 205.56  Testing by the Administrator.

    (a)(1) The Administrator may require that any vehicles to be tested 
pursuant to the Act be submitted to him, at such place and time as he 
may reasonably designate and in such quantity and for such time as he 
may reasonably require for the purpose of conducting tests in accordance 
with test procedures described in Sec. 205.54 to determine whether such 
vehicles or a manufacturer's test facility conform to applicable 
regulations. It is a condition of the requirements under this section 
that the manner in which the Administrator conducts such tests, the EPA 
test facility itself, and the test procedures he employs shall be based 
upon good engineering practice and meet or exceed the requirements of 
Sec. 205.54 of the regulations.
    (2) The Administrator may specify that he will conduct such testing 
at the manufacturer's facility, in which case instrumentation and 
equipment of the type required by these regulations shall be made 
available by the manufacturer for test operations. The Administrator may 
conduct such tests with his own equipment, which shall equal or exceed 
the performance specifications of the instrumentation or equipment 
specified by the Administrator in these regulations.
    (3) The manufacturer may observe tests conducted by the 
Administrator pursuant to this section on vehicles produced by such 
manufacturer and may copy the data accumulated from such tests. The 
manufacturer may inspect any such vehicles before and after testing by 
the Administrator.
    (b)(1) If, based on tests conducted by the Administrator or other 
relevant information, the Administrator determines that the test 
facility does not meet the requirements of Sec. 205.54-1 (a) and (b) he 
will notify the manufacturer in writing of his determination and the 
reasons therefor.
    (2) The manufacturer may at any time within 15 days after receipt of 
a notice issued under paragraph (b)(1) of this section request a hearing 
conducted in accordance with 5 U.S.C. 554 on the issue of whether his 
test facility was in conformance. Such notice will not take effect until 
15 days after receipt by the manufacturer, or if a hearing is requested 
under this paragraph, until adjudication by the hearing examiner.
    (3) After any notification issued under paragraph (b)(1) of this 
section has taken effect, no data thereafter derived from such test 
facility will be acceptable for purposes of this part.
    (4) The manufacturer may request in writing that the Administrator 
reconsider his determination under paragraph (b)(1) of this section 
based on data or information which indicates that changes have been made 
to the test facility and such changes have resolved the reasons for 
disqualification.
    (5) The Administrator will notify the manufacturer of his 
determination and an explanation of the reasons underlying it with 
regard to the requalification of the test facility within 10 working 
days after receipt of the manufacturer's request for reconsideration 
pursuant to paragraph (b)(4) of this section.
    (c)(1) The Administrator will assume all reasonable costs associated 
with shipment of vehicles to the place designated pursuant to paragraph 
(a) of this section except with respect to:
    (i) [Reserved]
    (ii) Testing of a reasonable number of vehicles for purposes of 
selective enforcement auditing under Sec. 205.57 or testing of smaller 
numbers of vehicles, if the manufacturer has failed to establish that 
there is a correlation between its test facility and the EPA test 
facility or the Administrator has reason to believe, and provides the 
manufacturer a statement of such reasons, that the vehicles to be tested 
would fail to meet the standard prescribed in this subpart if tested at 
the EPA test facility, but

[[Page 111]]

would meet such standard if tested at the manufacturer's test facility;
    (iii) Any testing performed during a period when a notice of 
nonconfor- mance of the manufacturer's test facility issued pursuant to 
paragraph (b) of this section is in effect;
    (iv) Any testing performed at place other than the manufacturer's 
facility as a result of the manufacturer's failure to permit the 
Administrator to conduct or monitor testing as required by this part.

Sec. 205.57-1  Test request.

    (a) The Administrator will request all testing under Sec. 205.57 by 
means of a test request addressed to the manufacturer.
    (1) Except as provided in paragraphs (a) (2) and (3) of this 
section, the Administrator will not issue to a manufacturer during any 
model year more test requests than a number determined by dividing the 
total number of vehicles subject to this regulation which the 
manufacturer projects he will produce during that model year by 25,000 
and rounding to the next higher whole number: Except, that the 
Administrator may issue one additional test request beyond the annual 
limit to any manufacturer for each time a batch sequence for any 
category, configuration or subgroup thereof of such manufacturer's 
production is rejected in accordance with Sec. 205.57-7.
    (2) Any test request issued against a category, configuration or 
subgroup thereof which the Administrator has reason to believe does not 
meet the standards specified in Sec. 205.52 will not be counted against 
the annual limit on test requests described in paragraph (a)(1) of this 
section. Any such request shall include a statement of the 
Administrator's reason for such belief.
    (3) Any test request under which testing is not completed will not 
be counted against the annual limit on test requests described in 
paragraph (a)(1) of this section.
    (b) The test request will be signed by the Assistant Administrator 
for Enforcement or his designee. The test request will be delivered by 
an EPA Enforcement Officer to the plant manager or other responsible 
official as designated by the manufacturer.
    (c) The test request will specify the vehicle category, 
configuration or subgroup thereof selected for testing, the batch from 
which sampling is to begin, the batch size, the manufacturer's plant or 
storage facility from which the vehicles must be selected, the time at 
which a vehicle must be selected. The test request will also provide for 
situations in which the selected configuration or category is 
unavailable for testing. The test request may include an alternative 
category or configuration selected for testing in the event that 
vehicles of the first specified category or configuration are not 
available for testing because the vehicles are not being manufactured at 
the specified plant and/or are not being manufactured during the 
specified time or not being stored at the specified plant or storage 
facility.
    (d) Any manufacturer shall, upon receipt of the test request, select 
and test a batch sample of vehicles from two consecutively produced 
batches of the vehicle category or configurations specified in the test 
request in accordance with these regulations and the conditions 
specified in the test request.
    (e)(1) Any testing conducted by the manufacturer pursuant to a test 
request shall be initiated within such period as is specified within the 
test request: Except, that such initiation may be delayed for increments 
of 24 hours or one business day where ambient test site weather 
conditions, or other conditions beyond the control of the manufacturer, 
in any 24-hour period do not permit testing: Provided, That these 
conditions for that period are recorded.
    (2) The manufacturer shall complete emission testing on a minimum of 
five vehicles per day unless otherwise provided for by the Administrator 
or unless ambient test site conditions only permit the testing of a 
lesser number: Provided, that ambient test site weather conditions for 
that period are recorded.

[[Page 112]]

    (3) The manufacturer will be allowed 24 hours to ship vehicles from 
a batch sample from the assembly plant to the testing facility if the 
facility is not located at the plant or in close proximity to the plant: 
Except, that the Administrator may approve more time based upon a 
request by the manufacturer accompanied by a satisfactory justification.
    (f) The Administrator may issue an order to the manufacturer to 
cease to distribute into commerce vehicles of a specified category or 
configuration being manufactured at a particular facility if:
    (1) The manufacturer refuses to comply with the provisions of a test 
request issued by the Administrator pursuant to this section; or
    (2) The manufacturer refuses to comply with any of the requirements 
of this section.
    (g) A cease-to-distribute order shall not be issued under paragraph 
(f) of this section if such refusal is caused by conditions and 
circumstances outside the control of the manufacturer which renders it 
impossible to comply with the provisions of a test request or any other 
requirements of this section. Such conditions and circumstances shall 
include, but are not limited to, any uncontrollable factors which result 
in the temporary unavailability of equipment and personnel needed to 
conduct the required tests, such as equipment break-down or failure or 
illness of personnel, but shall not include failure of the manufacturer 
to adequately plan for and provide the equipment and personnel needed to 
conduct the tests. The manufacturer will bear the burden of establishing 
the presence of the conditions and circumstances required by this 
paragraph.
    (h) Any such order shall be issued only after a notice and 
opportunity for a hearing.

Sec. 205.57-2  Test vehicle sample selection.

    (a) Vehicles comprising the batch sample which are required to be 
tested pursuant to a test request in accordance with this subpart will 
be selected in the manner specified in the test request from a batch of 
vehicles of the category or configuration specified in the test request. 
If the test request specifies that the vehicles comprising the batch 
sample must be selected randomly, the random selection will be achieved 
by sequentially numbering all of the vehicles in the batch and then 
using a table of random numbers to select the number of vehicles as 
specified in paragraph (c) of this section based on the batch size 
designated by the Administrator in the test request. An alternative 
random selection plan may be used by a manufacturer: Provided, That such 
a plan is approved by the Administrator. If the test request does not 
specify that test vehicles must be randomly selected, the manufacturer 
shall select test vehicles consecutively.
    (1) Should a situation arise in which the configuration to be tested 
consists of only vehicles with automatic transmissions, they shall be 
tested in accordance with Sec. 205.54-1(c)(2).
    (2) If the configuration to be tested consists of both automatic 
transmission and standard transmission vehicles, the test vehicle shall 
be a standard transmission vehicle unless the manufacturer has reason to 
believe that the automatic transmission vehicle emits a greater sound 
level.
    (b) The Acceptable Quality Level is 10 percent. The appropriate 
sampling plans associated with the designated AQL are contained in 
Appendix I, Table II.
    (c) The appropriate batch sample size will be determined by 
reference to Appendix I, Table I and II. A code letter is obtained from 
Table I based on the batch size designated by the Administrator in a 
test request. The batch sample size will be obtained from Table II. The 
batch sample size will be equal to the maximum cumulative sample size 
for the appropriate code letter obtained from Table I plus an additional 
10 percent rounded off to the next highest number.
    (d) If the test request specifies that vehicles comprising the batch 
sample must be selected randomly, individual vehicles comprising the 
test sample will be randomly selected from the batch sample using the 
same random selection plan as in paragraph (a) of

[[Page 113]]

this section. Test sample size will be determined by entering Table II.
    (e) The test vehicle of the category, configuration or subgroup 
thereof selected for testing shall have been assembled by the 
manufacturer for distribution in commerce using the manufacturer's 
normal production process in accordance with Sec. 205.55-5(a).
    (f) Unless otherwise indicated in the test request, the manufacturer 
will select the batch sample from the production batch, next scheduled 
after receipt of the test request, of the category or configuration 
specified in the test request.
    (g) Unless otherwise indicated in the test request, the manufacturer 
shall select the vehicles designated in the test request for testing.
    (h) At their discretion, EPA Enforcement Officers, rather than the 
manufacturer, may select the vehicles designated in the test request.
    (i) The manufacturer will keep on hand all vehicles in the batch 
sample until such time as the batch is accepted or rejected in 
accordance with Sec. 205.57-6: Except, that vehicles actually tested and 
found to be in conformance with these regulations need not be kept.

Sec. 205.57-3  Test vehicle preparation.

    (a) Prior to the official test, the test vehicle selected in 
accordance with Sec. 205-57-2 shall not be prepared, tested, modified, 
adjusted, or maintained in any manner unless such adjustments, 
preparation, modification and/or tests are part of the manufacturer's 
prescribed manufacturing and inspection procedures, and are documented 
in the manufacturer's internal vehicle assembly and inspection 
procedures or unless such adjustments and/or tests are required or 
permitted under this subpart or are approved in advance by the 
Administrator. For purposes of this section, prescribed manufacturing 
and inspection procedures include quality control testing and assembly 
procedures normally performed by the manufacturer on like products 
during early production so long as the resulting testing is not biased 
by the procedure. In the case of imported products the manufacturer may 
perform adjustments, preparations, modification and/or tests normally 
performed at the port of entry by the manufacturer to prepare the 
vehicle for delivery to a dealer or customer.
    (b) Equipment or fixtures necessary to conduct the test may be 
installed on the vehicle: Provided, That such equipment or fixtures 
shall have no effect on the noise emissions of the vehicle, as 
determined by measurement methodology.
    (c) In the event of vehicle malfunction (i.e., failure to start, 
misfiring cylinder, etc.) the manufacturer may perform the maintenance 
that is necessary to enable the vehicle to operate in a normal manner.
    (d) No quality control, testing, assembly or selection procedures 
shall be used on the completed vehicle or any portion thereof, including 
parts and subassemblies, that will not normally be used during the 
production and assembly of all other vehicles of the category which will 
be distributed in commerce, unless such procedures are required or 
permitted under this subpart.

Sec. 205.58-2  Tampering.

    (a) For each configuration of vehicles covered by this part, the 
manufacturer shall develop a list of those acts which, in his judgment, 
might be done to the vehicle in use and which would constitute the 
removal or rendering inoperative of noise control devices or elements of 
design of the vehicle.
    (b) The manufacturer shall include in the owner's manual the 
following information:
    (1) The statement:

             Tampering With Noise Control System Prohibited

    Federal law prohibits the following acts or the causing thereof:
    (1) The removal or rendering inoperative by any person, other than 
for purposes of maintenance, repair, or replacement, of any device or 
element of design incorporated into any new vehicle for the purpose of 
noise control prior to its sale or delivery to the ultimate purchaser or 
while it is in use; or (2) the use of the vehicle after such device or 
element of design has been removed or rendered inoperative by any 
person.

    (2) The statement:

    Among those acts presumed to constitute tampering are the acts 
listed below.


Immediately following this statement, the manufacturer shall include the 
list developed under paragraph (a) of this section.
    (c) Any act included in the list prepared pursuant to paragraph (a) 
of this section is presumed to constitute tampering; however, in any 
case in which a proscribed act has been committed and it can be shown 
that such act resulted in no increase in the noise level of the vehicle 
or that the vehicle still meets the noise emission standard of 
Sec. 205.52, such act will not constitute tampering.
    (d) The provisions of this section are not intended to preclude any 
State or local jurisdiction from adopting and enforcing its own 
prohibitions against the removal or rendering inoperative of

    (a)(1) The manufacturer shall provide to the ultimate purchaser of 
each vehicle covered by this subpart written instructions for the proper 
maintenance, use and repair of the vehicle in order to provide 
reasonable assurance of the elimination or minimization of noise 
emission degradation throughout the life of the vehicle.
    (2) The purpose of the instructions is to inform purchasers and 
mechanics of those acts necessary to reasonably assure that degradation 
of noise emission level is eliminated or minimized during the life of 
the vehicle. Manufacturers should prepare the instructions with this 
purpose in mind. The instructions should be clear and, to the extent 
practicable, written in nontechnical language.
    (3) The instructions must not be used to secure an unfair 
competitive advantage. They should not restrict replacement equipment to 
original equipment or service to dealer service. Manufacturers who so 
restrict replacement equipment should be prepared to make public any 
performance specifications on such equipment.
    (b) For the purpose of encouraging proper maintenance, the 
manufacturer shall provide a record or log book which shall contain a 
schedule for the performance of all required noise emission control 
maintenance. Space shall be provided in this record book so that the 
purchaser can note what maintenance was done, by whom, where and when.

Sec. 205.154  Consideration of alternative test procedures.

    The Administrator may approve applications from manufacturers of 
motorcycles for the approval of test procedures which differ from those 
contained in this subpart so long as the alternative procedures have 
been demonstrated to correlate with the prescribed procedure. To be 
acceptable, alternative test procedures must be such that the test 
results obtained will identify all those test motorcycles which would 
not comply with the noise emission standards prescribed in Sec. 205.152 
when tested in accordance with the measurement methodology specified in 
Appendix I. After approval by the Administrator, testing conducted by 
manufacturers using alternative test procedures will be accepted by the 
Administrator for all purposes including, but not limited to, selective 
enforcement audit testing.

the highest A-weighted sound level (in dB).
    (iii) Testing in accordance with Sec. 205.160-4 of a vehicle 
selected in accordance with Sec. 205.160-2 which much be a vehicle of 
the configuration which is identified pursuant to paragraph (c)(1)(ii) 
of this section as having the highest sound pressure level (estimated or 
actual) within the category.
    (iv) Demonstrating compliance of that vehicle with the applicable 
standard when tested in accordance with the test procedure specified in 
Appendix I.
    (2) Where the requirements of paragraph (c)(1) of this section are 
complied with, all those configurations contained within a category are 
considered represented by the tested vehicle.
    (3) Where the manufacturer tests a vehicle configuration which has 
not been determined as having the highest sound pressure level of a 
category, but all other requirements of paragraph (c)(1) of this section 
are complied with, all those configurations contained within that 
category which are determined to have sound pressure levels not greater 
than the tested vehicle are considered to be represented by the tested 
vehicle; however, a manufacturer must for purposes of Testing by the 
Administrator and Selective Enforcement Auditing verify according to the 
requirements of (b)(1) and/or (c)(1) of this section any configurations 
in

[[Page 124]]

the subject category which have a higher sound pressure level than the 
vehicle configuration tested.
    (d) A manufacturer may elect for purposes of Testing by the 
Administrator and Selective Enforcement Auditing to use representative 
testing pursuant to paragraph (c) of this section for all or part of his 
product line.
    (e) The manufacturer has the following alternatives if any test 
vehicle is determined to not be in compliance with applicable standards:
    (1) In the case of representative testing, a new test vehicle from 
another configuration must be selected according to the requirements of 
paragraph (c) of this section, in order to verify the configurations 
represented by the non-compliant vehicle.
    (2) Modify the test vehicle and demonstrate by testing that it meets 
applicable standards. The manufacturer must modify all production 
vehicles of the same configuration in the same manner as the test 
vehicle before distribution into commerce.

Sec. 205.159  Testing by the Administrator.

    (a)(1) In order for the Administrator to determine whether such 
vehicles or a manufacturer's test facility conform to applicable 
regulations, the Administrator may require that vehicles to be tested 
pursuant to the Act be submitted to him, at such place and time as he 
reasonably designates. He may designate the quantity of vehicles and the 
duration of time he reasonably requires for the purpose of conducting 
tests in accordance with test procedures described in appendix I. The 
manner in which the Administrator conducts such tests, the EPA test 
facility, and the test procedures employed will be based upon good 
engineering practice and meet or exceed the requirements of appendix I 
of the regulations.
    (2) If the Administrator specifies that he will conduct such testing 
at the manufacturer's facility, the manufacturer shall make available 
instrumentation and equipment of the type required for test operations 
by these regulations. The Administrator may conduct such tests with his 
own equipment, having specifications equal to or exceeding the 
performance specifications of the instrumentation and equipment required 
in these regulations.
    (3) The manufacturer may observe tests conducted by the 
Administrator pursuant to this section on vehicles produced by the 
manufacturer and may copy the data accumulated from such tests. The 
manufacturer may inspect any of the vehicles before and after testing by 
the Administrator.
    (b)(1) If, based on tests conducted by the Administrator, or on 
other relevant information, the Administrator determines that the test 
facility does

[[Page 126]]

not meet the requirements of appendix I (or the requirements for an 
alternative test procedure approved under Sec. 205.154), the 
Administrator will give notice to the manufacturer in writing of his 
determination and the reasons underlying it.
    (2) The manufacturer may, at any time within 15 days after receipt 
of a notice issued under paragraph (b)(1) of this section, request a 
hearing conducted in accordance with 5 U.S.C. 554 on the issue of 
whether his test facility met the requirements as specified in appendix 
I (or the alternative procedure). Such notice will not take effect until 
15 days after its receipt by the manufacturer or, if a hearing is 
requested under this paragraph, until adjudication by the Administrative 
law judge.
    (3) After any notice issued under paragraph (b)(1) of this section 
has taken effect, no data thereafter derived from that test facility 
will be acceptable for purposes of this subpart.
    (4) The manufacturer may request in writing that the Administrator 
reconsider his determination under paragraph (b)(1) of this section 
based on data or information which indicates that changes have been made 
to the test facility and that those changes have resolved the reasons 
for disqualification.
    (5) Within 10 working days after receipt of the manufacturer's 
request for reconsideration pursuant to paragraph (b)(4) of this 
section, the Administrator will notify the manufacturer of his 
determination and of the reasons underlyng it with regard to the 
requalification of the test facility.
    (c) The Administrator will assume all reasonable costs associated 
with shipment of vehicles to the place designated pursuant to paragraph 
(a) of this section except with respect to:
    (1) Any production verification testing performed at a place other 
than the manufacturer's facility as provided in Sec. 205.157-2(a), or as 
a result of the manufacturer's not owning or having access to a test 
facility;
    (2) Testing of a reasonable number of vehicles (i) for purposes of 
selective enforcement auditing under Sec. 205.160, (ii) or if the 
manufacturer has failed to establish that there is a correlation between 
its test facility and the EPA test facility, (iii) or the Administrator 
has reason to believe, and provides the manufacturer with a statement of 
such reason, that the vehicles to be tested would fail to meet the 
standard prescribed in this subpart if tested at the EPA test facility 
even though they would meet such standard if tested at the 
manufacturer's test facility;
    (3) Any testing performed during a period when a notice issued 
pursuant to paragraph (b) of this section is in effect;
    (4) Any testing performed at a place other than the manufacturer's 
facility as a result of the manufacturer's failure to permit the 
Administrator to conduct or monitor testing as required by this subpart; 
and
    (5) Testing of up to 10 percent of the manufacturer's test vehicles 
for a model year if the Administrator determines testing these vehicles 
at the EPA test site is necessary to assure that a manufacturer has 
acted or is acting in compliance with the Act.

Sec. 205.160-1  Test request.

    (a) The Administrator will request all testing under Sec. 205.160 by 
means of a test request addressed to the manufacturer.
    (b) The test request will be signed by the Assistant Administrator 
for Enforcement or his designee. The test request will be delivered to 
the plant manager or other responsible official as designated by the 
manufacturer.
    (c) The test request will specify the vehicle category, 
configuration or configuration subgroup selected for testing, the 
manufacturer's plant or storage facility from which the vehicles must be 
selected, and the time at which the vehicles must be selected. The test 
request will also provide for situations in which the selected category, 
configuration, or configuration subgroup is unavailable for testing. The 
test request may include an alternative category, configuration, or 
configuration subgroup designated for testing in the event that vehicles 
of

[[Page 127]]

the first specified category, configuration, or configuration subgroup 
are not available for testing because the vehicles are not being 
manufactured at the specified plant, are not being manufactured during 
the specified time, or are not being stored at the specified plant or 
storage facility.
    (d)(1) If the manufacturer projects a yearly production of fewer 
than 50 vehicles of the specified category, configuration or 
configuration subgroup to be tested, then within five (5) days of 
receipt of the request, the manufacturer must notify the Administrator 
of such low volume production. The Administrator will then provide a 
revised test request specifying a testing plan which imposes no greater 
risk of failure (5%) at the acceptable quality level (10%) than the plan 
in Appendix II. Upon receipt of the revised test request, the 
manufacturer must select and test a sample of vehicles from the 
category, configuration or configuration subgroup specified in the test 
request in accordance with this subpart and the conditions specified in 
the test request.
    (2) If the manufacturer produces 50 or more vehicles of the 
specified category, configuration or configuration subgroup per year, 
then upon receipt of the test request, the manufacturer must select and 
test a sample of vehicles from the category, configuration or 
configuration subgroup specified in the test request in accordance with 
this subpart and the conditions specified in the test request.
    (e)(1) Any testing conducted by the manufacturer under a test 
request must be initiated within the time period specified in the test 
request; except that initiation may be delayed for increments of 24 
hours or one business day where ambient test site weather conditions, or 
other conditions beyond the control of the manufacturer, in that 24-hour 
period, do not permit testing. The manufacturer must record the 
conditions for this period.
    (2) The manufacturer must complete noise emission testing on a 
minimum of ten vehicles per day unless otherwise provided by the 
Administrator or unless ambient test site conditions permit only the 
testing of a lesser number in which case the ambient test site weather 
conditions for that period must be recorded.
    (3) The manufacturer is allowed 24 hours to ship vehicles from a 
sample from the assembly plant to the testing facility if the facility 
is not located at the plant or in close proximity to the plant. The 
Administrator may approve more time based upon a request by the 
manufacturer accompanied by a satisfactory justification.
    (f) The Administrator may issue an order to the manufacturer to 
cease distribution in commerce of vehicles of a specified category, 
configuration, or configuration subgroup being manufactured at a 
particular facility, if:
    (1) The manufacturer refuses to comply with the provisions of a test 
request issued by the Administrator under this section; or
    (2) The manufacturer refuses to comply with any of the requirements 
of this section.
    (g) A cease distribution order will not be issued under paragraph 
(f) of this section if the manufacturer's refusal is caused by 
conditions and circumstances outside his control which render compliance 
with the provisions of a test request or with any other requirements of 
this section impossible. Conditions and circumstances outside the 
control of the manufacturer include, but are not limited to, the 
temporary unavailability of equipment and personnel needed to conduct 
the required tests caused by uncontrollable factors, such as equipment 
breakdown or failure or illness of personnel. Failure of the 
manufacturer to adequately plan for and provide the equipment and 
personnel needed to conduct the tests do not constitute uncontrollable 
factors. The manufacturer must bear the burden of establishing the 
presence of the conditions and circumstances required by this paragraph.

Sec. 205.160-2  Test sample selection and preparation.

    (a) Vehicles comprising the sample which are required to be tested 
under a test request in accordance with this subpart must be selected 
consecutively

[[Page 128]]

as they are produced. Before the official test, the test vehicle must 
not be prepared, tested, modified, adjusted, or maintained in any manner 
unless such preparation, tests, modifications, adjustments or 
maintenance are part of the manufacturer's prescribed manufacturing and 
inspection procedures, and are documented in the manufacturer's internal 
vehicle assembly and inspection procedures, are required or permitted 
under this subpart, or are approved in advance by the Administrator. For 
purposes of this section, prescribed manufacturing and inspection 
procedures include quality control testing and assembly procedures 
normally performed by the manufacturer on like products during early 
production if the resulting testing is not biased by this procedure. In 
the case of imported products, the manufacturer may perform adjustments, 
preparations, modification or tests normally performed at the port of 
entry by the manufacturer to prepare the vehicle for delivery to a 
dealer or customer.
    (1) Equipment or fixtures necessary to conduct the test may be 
installed on the vehicle if such equipment or fixtures have no effect on 
the noise emissions of the vehicle, as determined by the measurement 
methodology.
    (2) In the event of a vehicle malfunction (i.e., failure to start, 
etc.) the manufacturer may perform the maintenance that is necessary to 
enable the vehicle to operate in a normal manner. This maintenance must 
be documented and reported in the SEA report.
    (3) No quality control, quality assurance testing, assembly or 
selection procedures may be used on the test vehicle or any portion of 
the test vehicle including parts and subassemblies, unless such quality 
control, quality assurance testing, assembly or selection procedures are 
used normally during the production and assembly of all other vehicles 
of this configuration which will be distributed in commerce, are 
required or permitted under this subpart or are approved in advance by 
the Administrator.
    (4) If a vehicle is unable to complete the noise tests, the 
manufacturer may replace the vehicle. Any replacement vehicle must be a 
production vehicle of the same configuration as the replaced vehicle or 
a noisier configuration and will be subject to all the provisions of 
these regulations. Any replacement must be reported in the SEA report.
    (b) The Acceptable Quality Level (AQL) is 10 percent. The 
appropriate sampling plans associated with the designated AQL are 
contained in Appendix II or the test request.
    (c) The vehicles of the category, configuration or configuration 
subgroup selected for testing must be assembled by the manufacturer for 
distribution in commerce using the manufacturer's normal production 
process.
    (d) Unless otherwise indicated in the test request, the manufacturer 
must initiate testing with the vehicles of the category, configuration 
or configuration subgroup specified in the test request which are next 
scheduled for production after receipt of the test request.
    (e) The manufacturer must keep on hand all products in the test 
sample until the sample is accepted or rejected in accordance with 
Sec. 205.160-6; except that vehicles actually tested and found to be in 
conformance with this regulation need not be kept.

                  Subpart E--Motorcycle Exhaust Systems
 
Sec. 205.170  Testing by the Administrator.

    (a)(1) In order for the Administrator to determine whether such 
exhaust systems or a manufacturer's test facility conform to applicable 
regulations, the Administrator may require that exhaust systems to be 
tested pursuant to the Act be submitted to him, at such place and time 
as he reasonably designates. He may designate the quantity of exhaust 
systems and the duration of time he reasonably requires for the purpose 
of conducting tests in accordance with test procedures described in 
appendix I. The manner in which the Administrator conducts such tests, 
the EPA test facility, and the test procedures employed will be based 
upon good engineering practice and meet or exceed the requirements of 
appendix I.
    (2) If the Administrator specifies that he will conduct such testing 
at the manufacturer's facility, the manufacturer shall make available 
instrumentation and equipment of the type required for test operators by 
these regulations. The Administrator may conduct such tests with his own 
equipment, having specifications equal to or exceeding the performance 
specifications of the instrumentation and equipment required in these 
regulations.
    (3) The manufacturer may observe tests conducted by the 
Administrator pursuant to this section on exhaust systems produced by 
the manufacturer and may copy the data accumulated from such tests. The 
manufacturer may inspect any of the exhaust systems before and after 
testing by the Administrator.
    (b)(1) If, based on tests conducted by the Administrator or on other 
relevant information, the Administrator determines that the test 
facility does not meet the requirements of appendix I or the 
requirements for an alternative test procedure approved under 
Sec. 205.154, the Administrator will give notice to the manufacturer in 
writing of his determination and the reasons underlying it.
    (2) The manufacturer may, at any time within 15 days after receipt 
of a notice issued under paragraph (b)(1) of this section, request a 
hearing conducted in accordance with 5 U.S.C. 554 on the issue of 
whether his test facility met the requirements. Such notice will not 
take effect until 15 days after its receipt by the manufacturer, or, if 
a hearing is requested under this paragraph, until adjudication by the 
administrative law judge.
    (3) After any notice issued under paragraph (b)(1) of this section 
has taken effect, no data thereafter derived from that test facility 
will be acceptable for purposes of this subpart.
    (4) The manufacturer may request in writing that the Administrator 
reconsider his determination under paragraph (b)(1) of this section 
based on data or information which indicates that changes have been made 
to the test facility and that such changes have resolved the reasons for 
disqualification.
    (5) Within 10 working days after receipt of the manufacturer's 
request for reconsideration pursuant to paragraph (b)(4) of this 
section, the Administrator

[[Page 137]]

will notify the manufacturer of his determination and the reasons 
underlying it with regard to the requalification of the test facility.
    (c) The Administrator will assume all reasonable costs associated 
with shipment of exhaust systems to the place designated pursuant to 
paragraph (a) of this section except with respect to:
    (1) [Reserved]
    (2) Testing of a reasonable number of exhaust systems (i) for 
purposes of selective enforcement auditing under Sec. 205.171, or (ii) 
if the manufacturer has failed to establish that there is a correlation 
between its test facility and the EPA test facility, or (iii) the 
Administrator has reason to believe, and provides the manufacturer with 
a statement of such reason, that the exhaust systems to be tested would 
fail to meet the standard prescribed in this subpart if tested at the 
EPA test facility, even though they would meet such standard if tested 
at the manufacturer's test facility;
    (3) Any testing performed during a period when a notice of non- 
conformance of the manufacturer's test facility issued pursuant to 
paragraph (b) of this section is in effect;
    (4) Any testing performed at a place other than the manufacturer's 
facility as a result of the manufacturer's failure to permit the 
Administrator to conduct or monitor testing as required by this subpart; 
and
    (5) In addition to any exhaust systems included in paragraphs (c) 
(2), (3), or (4) of this section, testing of up to 10 percent of the 
manufacturer's exhaust systems for a model year if the Administrator 
determines testing these exhaust systems at the EPA test site is 
necessary to assure that a manufacturer has acted or is acting in 
compliance with the Act.

                  Subpart E--Motorcycle Exhaust Systems
 
Sec. 205.171-1  Test request.

    (a) The Administrator will request all testing under Sec. 205.171 by 
means of a test request addressed to the manufacturer.
    (b) The test request will be signed by the Assistant Administrator 
for Enforcement or his designee. The test request will be delivered to 
the plant manager or other responsible official as designated by the 
manufacturer.
    (c) The test request will specify the exhaust system category, model 
and model year of motorcycle selected for testing, the manufacturer's 
plant or storage facility from which the exhaust systems must be 
selected, the method of selection and the time at which the exhaust 
systems must be selected. The test request will also provide for 
situations in which the selected exhaust system is unavailable for 
testing. The test request may include an alternative exhaust system 
category designated for testing in the event that exhaust systems of the 
first specified category are not available for testing because the 
exhaust systems are not being manufactured at the specified plant or are 
not being manufactured during the specified time or are not being stored 
at the specified plant or storage facility.
    (d)(1) If the manufacturer projects a yearly production of fewer 
than 50 exhaust systems of the specified category to be tested, then, 
within five (5) days of receipt of the request, the manufacturer must 
notify the Administrator of such low volume production. The 
Administrator will then provide a revised test request specifying a 
testing plan which imposes no greater risk of failure (5%) at the 
acceptable quality level (10%) than the plan in appendix II. Upon 
receipt of the revised test request, the manufacturer must select and 
test a sample of exhaust systems from the category specified in the test 
request in accordance with this subpart and the conditions specified in 
the test request.
    (2) If the manufacturer produces 50 or more of the specified 
category, then,

[[Page 138]]

upon receipt of the test request, the manufacturer must select and test 
a sample of exhaust systems for the category specified in the test 
request in accordance with this subpart and the conditions specified in 
the test request.
    (e)(1) Any testing conducted by the manufacturer under a test 
request must be initiated within the time period specified in the test 
request; except that initiation may be delayed for increments of 24 
hours or one business day where ambient test site weather conditions, or 
other conditions beyond the control of the manufacturer, in that 24-hour 
period do not permit testing. The manufacturer must record the 
conditions for this period.
    (2) The manufacturer must complete noise emission testing on a 
minimum of ten exhaust systems per day unless otherwise provided by the 
Administrator or unless ambient test site conditions permit only the 
testing of a lesser number, in which event the ambient test site weather 
conditions for that period must be recorded.
    (3) The manufacturer is allowed 24 hours to ship exhaust systems 
from a sample from the assembly plant to the testing facility if the 
facility is not located at the plant or in close proximity to the plant. 
The Administrator may approve more time based upon a request by the 
manufacturer accompanied by a satisfactory justification.
    (f) The Administrator may issue an order to the manufacturer to 
cease distribution in commerce of exhaust systems of a specified 
category being manufactured at a particular facility if:
    (1) The manufacturer refuses to comply with the provisions of a test 
request issued by the Administrator under this section; or
    (2) The manufacturer refuses to comply with any of the requirements 
of this section.
    (g) A cease distribution order will not be issued under paragraph 
(f) of this section if the manufacturer's refusal is caused by 
conditions and circumstances outside his control which render compliance 
with the provisions of a test request or with any other requirements of 
this section impossible. Conditions and circumstances outside the 
control of the manufacturer include, but are not limited to, the 
temporary unavailability of equipment and personnel needed to conduct 
the required tests, caused by uncontrollable factors such as equipment 
breakdown or failure or illness of personnel. Failure of the

Sec. 205.171-8  Passing or failing under SEA.

    (a) A failing exhaust system is one which, when installed on any 
motorcycle which is in compliance with the requirements of subpart D and 
for which it is designed and marketed, together with such motorcycle 
produces a measured noise level in excess of the applicable noise 
emission standard in Sec. 205.166.
    (b) The number of failing vehicles in a sample determines whether 
the sample passes or fails (See applicable tables in appendix II). If 
the number of failing vehicles is greater than or equal to the number in 
Column B, the sample fails. If the number of failing vehicles is less 
than or equal to the number in Column A, the sample passes.
    (c) Pass or failure of a SEA takes place when a decision that an 
exhaust system is a passing or failing unit is made on the last exhaust 
system required to make a decision under paragraph (b) of this section.
    (d) If the manufacturer passes the SEA, he will not be required to 
perform any additional testing on subsequent exhaust systems to satisfy 
the test request.
    (e) The Administrator may terminate testing earlier than required in 
paragraph (b) of this section, based on a request by the manufacturer, 
accompanied by voluntarily ceasing distribution in commerce of exhaust 
systems from the category in question, manufactured at the plant which 
produced the exhaust systems being tested. Before reinitiating 
distribution in commerce of that exhaust system category from that 
plant, the manufacturer must take the action described in Sec. 205.171-
10(a)(1) and (2).

characteristics:
    (A) Steady-state accuracy of within <SUP>plus-minus</SUP>3% of 
actual engine speed in the range of 45% to 100% of the engine speed 
(RPM) where peak net brake power (maximum rated RPM) is developed; and
    (B) Response characteristics such that, when closing RPM is 
indicated under an acceleration as described below, actual engine speed 
is no more than 3 percent (of closing RPM) greater than the specified 
closing RPM.
    (ii) The vehicle tachometer may be used to ascertain:
    (A) The approach RPM provided it meets the specifications in 
paragraph (a)(3)(i)(A).
    (B) The closing RPM provided it meets the specifications in 
paragraphs (a)(3)(i)(A) and (B).
    (iii) Indirect engine speed measurement systems, such as systems 
which determine engine speed from vehicle speed measurement, may be used 
provided the specifications of paragraph (a)(1)(i) are met.
    (4) An anemometer with steady-state accuracy of within 
<SUP>plus-minus</SUP>10% at 20 km/h (12.4 mph).
    (5) A microphone wind screen which does not affect microphone 
response more than <SUP>plus-minus</SUP>0.5 dB for frequencies of 20-
4000 Hz or <SUP>plus-minus</SUP>1.0 dB for frequencies of 4000-10,000 
Hz, taking into account the orientation of the microphone.
    (b) Test site. (1) The measurement area within the test site must 
meet the following requirements and be laid out as described:
    (i) The following points must be established:
    (A) Microphone target point--a reference point on the vehicle path;
    (B) End point--a point on the vehicle path 7.5 <SUP>plus-minus</SUP> 
0.3m (24.6 <SUP>plus-minus</SUP> 1.0 ft) beyond the microphone target 
point, and
    (C) Microphone location point--a point 15<SUP>plus-minus</SUP> 0.3m 
(49.2 <SUP>plus-minus</SUP> 1.0 ft) from the microphone target point on 
a normal to the vehicle path through the microphone target point.
    (ii) The microphone must be:
    (A) Positioned at the microphone location point 1.2 <SUP>plus-minus</SUP> 
0.1 m (3.9 <SUP>plus-minus</SUP> 0.3 ft) above the ground plane; and
    (B) Oriented in a plane perpendicular to the vehicle path, and at an 
angle for which the microphone was calibrated to have the flatest 
response characteristics over the frequency range of 100 Hz to 10,000 Hz 
when measured with respect to the motorcycle source.
    (iii) The surface of the ground within at least the triangular area 
formed by the microphone location and the points 15 <SUP>plus-minus</SUP> 
0.3m (49.2 <SUP>plus-minus</SUP>1.0 ft.) prior to and 15 <SUP>plus-minus</SUP> 
0.3 m (49.2 <SUP>plus-minus</SUP> 1.0 ft.) beyond the microphone target 
point must be flat (+ 5 cm (2.0 in)) and level (grade not more than 0.5% 
along vehicle path), have a concrete or sealed asphalt surface, and be 
free from snow, soil or other extraneous material.
    (iv) The vehicle path must be relatively smooth and of sufficient 
length for safe acceleration, deceleration and stopping of the 
motorcycle.
    (2) The test site must be flat, open space free of large sound-
reflecting surfaces (other than the ground), such as parked vehicles, 
sign-boards, buildings or hillsides located within a 30 <SUP>plus-minus</SUP> 
0.3 m (98.4 <SUP>plus-minus</SUP> 1.0 ft) radius of the microphone 
location and the following points on the vehicle path (see Figure 1):
    (i) The microphone location point;
    (ii) A point 15 <SUP>plus-minus</SUP> 0.3 m (49.2 <SUP>plus-minus</SUP> 
1.0 ft.) before the microphone target point; and
    (iii) A point 15 <SUP>plus-minus</SUP> 0.3 m (49.2 <SUP>plus-minus</SUP> 
1.0 ft) beyond the microphone target point.
    (c) Measurement procedure.
    (1) To establish the acceleration point, the end point must be 
approached in second gear from the reverse of the intended test 
direction at a constant engine speed of 50% of maximum rated RPM or 
closing RPM less ten percent (of maximum rated RPM), whichever is lower, 
(<SUP>plus-minus</SUP>2.5% of observed reading). When the front of the 
motorcycle

[[Page 144]]

reaches the end point (approached from the reverse direction), the 
throttle must be smoothly and fully opened to accelerate the motorcycle 
past the microphone target point under wide open throttle. When the 
motorcycle reaches closing RPM the throttle must be smoothly and fully 
closed. An ignition disable device may be used to turn off the engine at 
closing RPM in lieu of closing the throttle manually. The location of 
the front of the motorcycle at the time of throttle closure is the 
acceleration point for the test runs. The test runs must be made in the 
opposite direction. A sufficient number of trial runs must be made to 
assure accurate establishment of the acceleration point.
    (2) Closing RPM must be determined according to the motorcycle 
engine displacement, as follows (see Figure 2):

------------------------------------------------------------------------
                                             Closing RPM (Fraction of
           Displacement (cc)               maximum rated RPM--percent)
------------------------------------------------------------------------
0 to 175...............................  95
176 to 675.............................  109 to 0.08 x (engine
                                          displacement in cc)
676 and above..........................  55
------------------------------------------------------------------------

    (3) The distance from the acceleration point to the end point must 
be at least 10 m (32.8 ft). If this distance is less than 10 m (32.8 ft) 
by the procedure specified in paragraph (c)(1), above, third gear, if 
the motorcycle is so equipped, must be used. If the distance is still 
less than 10 m (32.8 ft), fourth gear, if the motorcycle is so equipped, 
must be used, and so on. If closing RPM is reached before the vehicle 
travels 10 m (32.8 ft), with the vehicle in its highest gear, the 
throttle must be opened less rapidly, but in such a manner that full 
throttle and closing RPM are attained at the end point.
    (4) If the motorcycle is equipped with an automatic transmission, 
the procedure specified in paragraph (c)(1), must be followed except 
that the lowest selectable range must be employed, and the procedure 
specified in paragraph (c)(3) must be followed using the next selectable 
higher range, if necessary, and if the vehicle is so equipped. If 
closing RPM is reached before the vehicle travels 10 m (32.8 ft.), the 
throttle must be opened less rapidly, but in such a manner that full 
throttle and closing RPM are attained at the end point.
    (5) Throttle opening must be controlled to avoid excessive wheel 
slip or lift-off.
    (6) To conduct a sound measurement, the motorcycle must proceed 
along the vehicle path in the forward direction in second gear (or 
higher gear as applicable under paragraph (c)(3)) at a constant engine 
speed of 50% of maximum rated RPM or at closing RPM less ten percent (of 
maximum rated RPM), whichever is lower (<SUP>plus-minus</SUP> 2.5 
percent of observed reading). When the front of the vehicle reaches the 
acceleration point, the throttle must be smoothly and fully opened. Full 
acceleration must continue until closing RPM is reached, which must 
occur within <SUP>plus-minus</SUP> 1.0 m (3.3 ft.) of the end point, and 
at which time the throttle must be smoothly and fully closed. An 
ignition disable device may be used to turn off the engine at closing 
RPM in lieu of closing the throttle manually.
    (7) A sufficient number of preliminary runs must be conducted before 
the testing to familiarize the rider with the test procedure and 
operating conditions of the vehicle. The engine temperature must be 
within the normal operating range prior to each run.
    (d) Measurements. (1) The sound level meter must be set for fast 
response and for the A-weighting network. The microphone wind screen 
must be used. The sound level meter must be calibrated with the acoustic 
calibrator as often as is necessary throughout testing to maintain the 
accuracy of the measurement system.
    (2) The sound level meter must be observed throughout the 
acceleration period. The highest sound level obtained for the run must 
be recorded.
    (3) Measurements must be made until at least four readings from each 
side are within 2 dB of each other. The noise level for each side is the 
average of the four which are within 2 dB of each other. The noise level 
reported must be for that side of the motorcycle having the highest 
noise level.
    (4) While making sound level measurements, not more than one person 
other than the rider and the observer reading the meter may be within 15 
m (49.2 ft) of the vehicle or microphone, and that person must be 
directly behind the observer reading the meter, on a line through the 
microphone and the observer.
    (5) The ambient noise level (including wind effects) at the test 
site due to sources other than the motorcycle being measured must be at 
least 10 dB lower than the noise level at the microphone location 
produced by the motorcycle under test.
    (6) Wind speed at the test site during tests must be less than 20 
km/h (12.4 mph).
    (e) Required data. For each valid test, the following data must be 
recorded:
    (1) Motorcycle type, serial number, model year, and date of 
manufacture.
    (2) Names of persons conducting test.
    (3) Test location.
    (4) Wind speed and ambient noise level measured on the same day as 
the test and representative of conditions during the test.
    (5) Motorcycle engine displacement, maximum rated RPM, and closing 
RPM.

 that meet the definition of Sec. 205.151(a)(2)(ii) (moped-type street 
                              motorcycles)

    (a) Instrumentation. Proper usage of all test instrumentation is 
essential to obtain valid measurements. Operating manuals or other 
literature furnished by the instrument manufacturer must be referred to 
for both recommended operation of the instrument and precautions to be 
observed. The following instrumentation must be used, where applicable:
    (1) A sound level measurement system which meets the type SIA 
requirements of American National Standard Specification for Sound Level 
Meters, ANSI S1.4-1971. As an alternative to making direct measurements 
using a sound level meter, a microphone or sound level meter may be used 
with a magnetic tape recorder and/or a graphic level recorder or 
indicating instrument provided that the system meets the performance 
requirements of ANSI S1.4-1971. The sound level measurement system must 
be calibrated at least annually to insure that the system meets the 
performance requirements of ANSI S1.4-1971.
    (2) An acoustic calibrator with an accuracy of within 
<SUP>plus-minus</SUP>0.5 dB. The calibrator must be checked annually to 
verify that its output is within the specified accuracy.
    (3) An anemometer with steady-state accuracy of within 
<SUP>plus-minus</SUP>10% at 20 km/h (12.4 mph).
    (4) A microphone wind screen which does not affect microphone 
response more than <SUP>plus-minus</SUP>0.5 dB for frequencies of 20-
4000 Hz or <SUP>plus-minus</SUP>1.0 dB for frequencies of 4000-10,000 
Hz, taking into account the orientation of the microphone.
    (b) Test site. (1) The measurement area within the test site must 
meet the following requirements and be laid out as described:
    (i) The following points must be established:
    (A) Microphone target point--a reference point on the vehicle path;
    (B) End point--a point on the vehicle path 
7.5<SUP>plus-minus</SUP>0.3 m (24.6<SUP>plus-minus</SUP>1.0 ft) beyond 
the microphone target point; and
    (C) Microphone location point--a point 15<SUP>plus-minus</SUP>0.3 m 
(49.2<SUP>plus-minus</SUP>1.0 ft) from the microphone target point on a 
normal to the vehicle path through the microphone target point. 
Alternately, the microphone location point may be a point 
7.5<SUP>plus-minus</SUP>0.3 m (24.6<SUP>plus-minus</SUP>1.0 ft) from the 
microphone target point provided that the sound level reported is 
adjusted as provided in this appendix under paragraph (d)(3).
    (ii) The microphone must be:
    (A) Positioned at the microphone location point 
1.2<SUP>plus-minus</SUP>0.1 m (3.9<SUP>plus-minus</SUP>0.3 ft) above the 
ground plane; and
    (B) Oriented in a plane perpendicular to the vehicle path, and at an 
angle for which the microphone was calibrated to have the flattest 
response characteristics over the frequency range of 100 Hz to 10,000 Hz 
when measured with respect to the motorcycle source.
    (iii) The surface of the ground within at least the triangular area 
formed by the microphone location and the points 
15<SUP>plus-minus</SUP>0.3 m (49.2<SUP>plus-minus</SUP>1 ft) prior to 
and 15<SUP>plus-minus</SUP>0.3 m beyond the microphone target point must 
be flat (<SUP>plus-minus</SUP>5 cm (2.0 in)) and level (grade not more 
than 0.5% along vehicle path), have a concrete or sealed asphalt 
surface, and be free from snow, soil or other extraneous material.
    (iv) The vehicle path must be relatively smooth and of sufficient 
length for safe acceleration, deceleration and stopping of the 
motorcycle.
    (2) The test site must be a flat, open space free of large sound-
reflecting surfaces (other than the ground), such as parked vehicles, 
signboards, buildings or hillsides located within a 
30<SUP>plus-minus</SUP>0.3 m (98.4<SUP>plus-minus</SUP>1.0 ft) radius of 
the microphone location and the following points on the vehicle path 
(see Figure 1):
    (i) The microphone location point;
    (ii) A point 15<SUP>plus-minus</SUP>0.3 m 
(49.2<SUP>plus-minus</SUP>1 ft) before the microphone target point; and
    (iii) A point 15<SUP>plus-minus</SUP>0.3 m 
(49.2<SUP>plus-minus</SUP>1 ft) beyond the microphone target point.
    (c) Measurement procedure. (1) The combined weight of the test rider 
and test equipment used on the motorcycle must not be more than 80 kg 
(176 lb) nor less than 75 kg (165 lb). Weights shall be placed on the 
motorcycle saddle behind the rider to compensate for any difference 
between the actual driver/equipment load and the required 75 kg (165 lb) 
minimum.
    (2) The motorcycle must approach the microphone target point with 
the throttle fully open and in the highest gear. The motorcycle must 
start such that maximum speed is reached before the vehicle is within 
7.5 m of the microphone target point. The motorcycle must continue along 
the vehicle path with fully open throttle and at maximum speed past the 
end point, at which time the throttle must be closed.
    (3) If the motorcycle is equipped with an automatic transmission, 
the procedure of paragraph (1), above, must be followed except

[[Page 146]]

that the highest selectable range shall be employed.
    (d) Measurements. (1) The sound level meter must be set for fast 
response and for the A-weighting network. The microphone wind screen 
must be used. The sound level meter must be calibrated with the acoustic 
calibrator as often as is necessary throughout testing to maintain the 
accuracy of the measurement system.
    (2) The sound level meter must be observed throughout the passby 
period. The highest noise level obtained for the run must be recorded.
    (3) At least three measurements shall be made for each side of the 
motorcycle. Measurements must be made until at least three readings from 
each side are within 2 dB of each other. The noise level for each side 
must be the average of the three. The noise level reported must be for 
that side of the motorcycle having the highest noise level. If the 
microphone location point is 7.5 m from the vehicle path as allowed in 
this appendix under paragraph (b)(1)(i)(c), the noise level must be 
adjusted by subtracting 6 dB prior to being reported.
    (4) While making noise level measurements, not more than one person 
other than the rider and the observer reading the meter may be within 15 
m (49.2 ft) of the vehicle or microphone, and that person must be 
directly behind the observer reading the meter, on a line through the 
microphone and the observer.
    (5) The ambient sound level (including wind effects) at the test 
site due to sources other than the motorcycle being measured must be no 
greater than 60 dB if the microphone is located 15 m from the vehicle 
path or 66 dB if the microphone is located 7.5 m from the vehicle path 
as allowed in this appendix under paragraph (b)(1)(i)(c).
    (6) Wind speed at the test site during tests must be less than 20 
km/h (12.4 mph).
    (e) Required data. For each valid test, the following data must be 
recorded:
    (1) Motorcycle type, serial number, model year, and date of 
manufacture.
    (2) Names of persons conducting test.
    (3) Test location.
    (4) Wind speed and ambient noise level measured on the same day as 
the test and representative of conditions during the test.
    (5) Description of the sound level meter including type, serial 
number, and calibration date.
    (6) Description of the external acoustic calibrator including type, 
serial number, and calibration date.
    (7) Maximum noise level for each pass on each side of the motorcycle 
including invalid readings and reasons for invalidation.
