The Government reserves the right to perform aray of the inspections set forth in the specification where such inspections are deemed necessary to insure that supplies and services con- fo
8、rm to prescribed requirements. 4.1.1 Responsibility for compliance. 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 quaity program. The absence of any inspection requirements
9、 in the specification shal not relieve the contractor of the responsibility of assuring that all products or supplies submitted to the Government for acceptance comply with all require- ments of the contract. Sampling in quality conformance does not authorize sub- mission of known defective material
10、, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Objective evidence. The contractor shall provide objective evidence acceptable %o the contracting officer that the requirements of 3.1 and section 5 for which specific inspection has not been p
