Sec. 205.57-6  Acceptance and rejection of batches.

    (a) The batch from which a batch sample is selected will be accepted 
or rejected based upon the number of failing vehicles in the batch 
sample. A sufficient number of test samples will be drawn from the batch 
sample until the cumulative number of failing vehicles is less than or 
equal to the acceptance number or greater than or equal to the rejection 
number appropriate for the cumulative number of vehicles tested. The 
acceptance and rejection numbers listed in Appendix I, Table II at the 
appropriate code letter obtained according to Sec. 205.57-2 will be used 
in determining whether the acceptance or rejection of a batch has 
occurred.
    (b) Acceptance or rejection of a batch takes place when the decision 
that a vehicle is a failing vehicle is made on the last vehicle required 
to make a decision under paragraph (a) of this section.
