Unless otherwise specified in the contract or purchase order (see 6.2), the contractor is responsible far the performance of all inspection requ
25、irements (examinations and tests) sipecif ied herein. Except as 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 Govern
26、ment reserves the right to perform any of the inspections 5et +orth in the specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all require- ments of sections 3 and 5. T
27、he inpection 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 shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted
28、 to the Government for acceptance comply with all requirements of the contract. Sampling inepection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submicsion of known defective material, either indicated or a
29、ctual, nor does it commit the Qovernment to accept defective material. 4.2 Classification of inspections, The inspection requirements specified herein are classified as follows: a. First article inspection (see 4.5). b. Quality conformance inspection (see 4.6). 4 Provided by IHSNot for ResaleNo repr
