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 desig nated 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 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.
