The Government reserves the right to perform any of t

19、he inspections set forth in this document where such inspections are deemed necessary to assure supplies and services conform 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 document shall bec

20、ome a part of the contractors overall inspection system or quality program. The absence of any inspection requirement in the document shall not relieve the contractor of the responsibility of assuring that all products or supplies submitted to the Government for acceptance comply with all requiremen

21、ts of the contract. Sampling in quality conformance does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Certificates of compliance.

22、nment reserves the right to inspect such items to determine the validity of the certification. 4.2 Quality conformance inspection. Unless otherwise specified, sampling for inspection shall be performed in accordance with MIL-STD-105. 4.2.1 Marking examination. During the examination of the end item

23、(cloth or blanket), each unit in the sample shall be examined for conformance to the special marking requirements (see 3.5). Each unit not marked as specified shall be a defect. The examination shall be performed in conjunction with the “Examination For Compliance with the Wool Products Labeling Act
