Lot recertification process – PRAT testing. 10% of the first lot sample shall be used with a minimum quantity of 2 samples for Group C testing

Lot Acceptance Test Procedure (Operational thermal limits) - 10% of all units after successful completion of Group A testing a minimum quantity of 4 samples shall be used. Samples pulled from lot at equally spaced periods of production run. Failure of 2 or more sample units will require hold of that portion of the lot and failure analysis performed to establish root cause of failure, if appropriate, corrective action will be required and lot disposition can be provided

Acceptance Test Procedure (Ambient Temperature) - 100% of all units after successful completion of ESS. Each unit must pass all functional performance criteria for acceptance. All units which fail to pass can be returned to production for rework

Lot recertification process – PRAT testing. 10% of the first lot sample with a minimum quantity of 2 samples shall be used for Group D testing
