Unless otherwise specified in the contract: (ar purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tes
29、ts) as specified herein. Except os otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government: reserves the right to p
30、erform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conorm to prescribed requirements. 4.1.1 Responsibilitv for compliance. All items shall meet all requirements of sections 3 and 5. The inspection set forth in thi
31、s specification shall become a part o the contractors overall inspection system or quality program. absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance
32、comply with all requirements cf the contract. Sampling inspection, as part of the manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the
