36、for inmection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of di1 inspection requirements (examinations and tests) as specified herein. fl)rcept: as otherwise specified in the contract or purchase order, the contractor inay use his
37、own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. Tho Government reserves the right to perform any of the inspections set forth in this document where such inspections are deemed necessary to ensure supplie
38、s and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The inspection set forth in this document shall become a part of the contractors overall inspection system or quality program. absence of any inspection
39、requirements in this document shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice
40、to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. The 4.1.2 Responsibility for dimensional requirements. Unless otherwise specified in the cont
41、ract or purchase order, the contractor is responsible for ensuring that all specified dimensions have been met. When dimensions cannot be examined on the end item, inspection shall be made at any point, or at all points in the manufacturing process necessary to ensure compliance with all diiriension
