All items must meet all requirements of sections 3 and 5, The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspecti
13、on requirements in the specjfication shall not relieve the contractor of the responsibility of assuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract.

To retain qualification, the contractor shall forward a report at six month intervals to the qualifying activity. The qualifying activity shall establish the initial reporting d

The report shall consist of a summary of the results of the tests performed, indicating the number of samples that have passed and the number that have failed during the six month period. conformance with specification requirements, and corrective action acceptable to the qualifying activity ha

In the event that no production occurred during the reporting period, a report shall be submitted certifying that the company still has the capabilities and faci 1 i ties
