QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection.
16、Unless otherwise specified in the con- tract or purchase order, the contractor is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified in the contract or purchase order, the contractor my use his own or any other facilities suitable for th
17、e performance of the inspection requirements speci- fied herein, unless disapproved by 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 to prescribed
18、requirements . 4.1.1 Responsibility for compliance. All items must meet ail requirements of sections 3 and 5. 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 specific
19、ation shall 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 efective material, either indicat
20、ed or actual, nor does it commit the Government to acceptance of defective niaterial. 3 Licensed by Information Handling ServicesDOD-D-51524 68 m 7777706 OL22LLb 7 m DOD-D-51524 (EA) 4.2 Quality conformance inspection. 4.2.1 Lotting, A lot shall consist of the Dye, Disperse-Blue 3 offered for accept
