QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specifie
29、d in the contract or purchase order, the contractor is responsible for the performance of al 1 inspection requirements (examinations and test) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the
30、 performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed re
31、quirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of section 3. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in the specification sha
32、ll not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with al 1 requirements of the contract. Sampl ing inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to req
33、uirements; however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.2 Inspection conditions. Unless otherwise specified in the contract (see 6.2), all inspections shall be performed under th
