18、ed 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 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

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
