All items must meet all requirements of sectioin set forth in this sp
36、ecification 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 to the Government for acceptance
37、 comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the govern
38、ment to acceptance of defective material. 4.1.2 Certificate of compliance. Where certificates of compliance are submitted, the Government reserves the right to check test such i tems to determine the validity of the certification. 4.2 Classification of inspection. The inspection requirements specifi
39、ed herein are classified as follows: 1. First article inspection (see 4.3). 2. Quality conformance inspection (see 4.4). 4.3 First article inspection. When required, the first article submitted in accordance with 3.2, shall be inspected as specified in 4.4.2 for compliance with design, construction,
40、 workmanship, appearance and dimensional requirements. 4.4 Quality conformance inspection. Sampling for inspection shall be performed in accordance with MIL-STD-105, except where otherwise indicated. 4.4.1 Component and material inspect.ion. In accordance with 4.1 above, components and materials sha
41、ll be tested in accordance with all the requirements of referenced specifications, drawings, and standards unless otherwise excluded, amended, modified, or qualified in this specification or applicable procurement documents. 4.4.2 Examination of the end item. Examination of the end item shall be in
42、accordance with 4.4.2.1 through 4.4.2.4. 4.4.2.1 Length examination. The required length of each roll shall be examined on both sides and visual defects classified as listed in Table III. All defects found shall be counted, regardless of the proximity one to another, except where two or more defects
43、 represent a single local condition of the webbing, in which case only the more serious defect shall be counted. A continuous defect shall be counted as one defect for each warpwise yard or fraction thereof in which it occurs. The sample unit for this examination shall be one linear yard each. An ap
44、proximate equal number of yards shall be examined from each roll selected. The number of rolls from which the sample is to be selected shall be in accordance with Table II of this specification. 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-flIL-
