29、orm any of the inspections set forth 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 requirements of Sections 3 and 5. The inspection set forth in this
30、 specification shall become a part of the contractor?s 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 accept
31、ance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an 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
32、 Government 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 items to determine the validity of the certification. 4.2 Classification of inspection. The inspection requirements s
33、pecified herein are classified as follows: 1. 2. First article inspection (see 4.3). Quality conformance inspection (see 4.4). 4.3 First article inspection. When required, the first article submitted in accordance with 3.2, shall be visually inspected for compliance with color, finish, and appearanc
34、e and shall be tested for the chemical and physical properties in accordance with the applicable methods specified in 4.5. 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 i
35、nspection. In accordance with 4.1 above, components and materials shall be inspected and 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 doc
36、uments. In addition, the contractor shall furnish a certificate of compliance for the coating compound formulation requirement specified in 3.3.2 and for the non-mildew supporting characteristic of the dusting medium specified in 3.5. 4.4.2 Examination of the end item. Examination of the end item sh

The required yardage of each roll shall be inspected on one side only.
38、However, the side shall be alternated, so that alternate rolls are examined on the face and back respectively. The defects found shall be classified as listed below. In addition, the cloth shall be given a through-light inspection for pinholes. The through-lighting inspection shall be performed in a
39、ccordance with MIL-STD-1487. The defects found shall be counted, regardless of their proximity to each other, except where two or more defects represent a single local condition of the cloth, in which case only the more serious defect shall be counted. The lot size shall be expressed in units of one
40、 linear yard. The sample unit for this examination shall be one linear yard. The acceptable quality levels (AQL) for this examination shall be 1.5 for major defects and 4.0 for total defects (major and minor) per 100 units (yards). The inspection level shall be level II. The number of rolls from whi
41、ch the sample is to be selected shall be in accordance with Table II, An approximately equal number of yards shall be examined in each roll sampled. Defect Major Minor Classification I.
