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.
