Sec.  204.57-6  Acceptance and rejection of batches.



    (a) A failing compressor is one whose measured sound level is in 

excess of the applicable noise emission standard.

    (b) The batch from which a batch sample is selected will be accepted 

or rejected based upon the number of failing compressors in the batch 

sample. A sufficient number of test samples will be drawn from the batch 

sample until the cumulative number of failing compressors is less than 

or equal to the acceptance number or greater than or equal to the 

rejection number appropriate for the cumulative number of compressors 

tested. The acceptance and rejection numbers listed in Appendix I, Table 

II at the appropriate code letter obtained according to Sec.  204.57-2 

will be used in determining whether the acceptance or rejection of a 

batch has occurred.

    (c) Acceptance or rejection of a batch takes place when a decision 

is made on the last compressor required to make a decision under 

paragraph (b) of this section.
