QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection - Unless otherwise specified in the contract or purchase order, the supplier is responsible for the performance of all inspection requirements as specified herein, Except as otherwis

19、e specified, the supplier may utilize his own facilities or any commercial laboratory acceptable to the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform t

20、o prescribed requirements. 4.2 Classification of inspection - The examination and testing of the adapters shall be classified as follows: Preproduction inspection - Preproduction inspection consists of examinations and tests performed on adapters which are representative of the production item after

21、 award of a contract to determine that the production item meets the requirements of this specification. Quality conformance inspection - Quality conformance inspection consists of examinations and tests per- forked on individual products or lots to determine conformance of the products or lots with

22、 the require- ments set forth in this specification. 4.3 Preproduction inspection - The preproduction inspection of the adapters shall consist of examinations and tests for all the require- - ments of this specification. 4.3.1 Preproduction samples - 4.3.1.1 Applicable to the Bureau of Naval Weapons

23、 - Unless other- wise specified, as soon as practicable after award of the contract or order, the manufacturer shall submit twelve adapters of the MS part number contracted for, three for each of the three strength tests, and three adapters for the vibration and endurance tests, The samples shall be

24、 representative of the construction, workmanship, components, and materials to be used during production. When a manufacturer is in continuous pro- duction of these adapters from contract to contract, submission of further preproduction samples on the new contract may be waived at the discretion of

25、the procuring activity, Approval of the preproduction samples or the waiving of preproduction inspection does not preclude the requirements of submitting to the quality conformance inspection.
