                   Subpart B_Portable Air Compressors

 

Sec.  204.57-2  Test compressor sample selection.



    (a) Compressors comprising the batch sample which are required to be 

tested pursuant to a test request in accordance with this subpart will 

be randomly selected from a batch of compressors of the category or 

configuration specified in the test request. The random selection will 

be achieved by sequentially numbering all of the compressors in the 

batch and then using a table of random numbers to select the number of 

compressors, as specified in paragraph (c) of this section, based on the 

batch size designated by the Administrator in the test request. An 

alternative selection plan may be used by a manufacturer: Provided, That 

such a plan is approved by the Administrator.

    (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, Tables 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 equal to the maximum 

cumulative sample size as listed in Table II for the appropriate code 

letter obtained from Table I plus an additional ten percent rounded off 

to the next highest number.

    (d) Individual compressors 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 compressor of the category or configuration selected 

for testing shall have been assembled by the manufacturer for 

distribution in commerce using the manufacturers normal production 

process.

    (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 compressors designated in the test request for testing.

    (h) At their discretion, EPA Enforcement Officers, rather than the 

manufacturer, may select the compressors designated in the test request.

    (i) The manufacturer will keep on hand all compressors in the batch 

sample until such time as the batch is accepted or rejected in 

accordance with Sec.  204.57-6; Except, that compressors actually tested 

and found to be in conformance with these regulations need not be kept.
