Sec. 204.57-7  Acceptance and rejection of batch sequence.

    (a) The manufacturer will continue to inspect consecutive batches 
until the batch sequence is accepted or rejected. The batch sequence 
will be accepted or rejected based upon the number of rejected batches. 
A sufficient number of consecutive batches will be inspected until the 
cumulative number of rejected batches is less than or equal to the 
sequence acceptance number or greater than or equal to the sequence 
rejection number appropriate for the cumulative number of batches 
inspected. The acceptance and rejection numbers listed in Appendix I, 
Table III 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 sequence has occurred.
    (b) Acceptance or rejection of a batch sequence takes places when 
the decision is made on the last compressor required to make a decision 
under paragraph (a) of this section.
    (c) If the batch sequence is accepted, the manufacturer will not be 
required to perform any additional testing on

compressors from subsequent batches pursuant to the initiating test 
request.
    (d) The Administrator may terminate testing earlier than required in 
paragraph (b) of this section based on a request by the manufacturer 
accompanied by voluntary cessation of distribution in commerce, from all 
plants, of compressors from the configuration in question: Provided, 
That once production is reinitiated, the manufacturer must take the 
action described in Sec. 204.57-9 (a)(1) and (a)(2) prior to 
distribution in commerce of any compressors from any plant of the 
compressor category or configuration in question.
