the sequence rejection number appropriate for the cumulative number of 
batches inspected. The acceptance and rejection numbers listed in

decision that a vehicle is a failiing vehicle is made on the last 
vehicle required to make a decision under paragraph (a) of this section.

required to perform any additional testing on vehicles from subsequent
