QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for t
31、he performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in-the contract or order, the contractor may use his own or any other facilities suitable for performance of the inspection requirements specified herein, unless disapproved by t

The Government reserves the right to perform 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 must meet all requirements
33、of Sections 3 and 5. The inspection 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 product
34、s or supplies submitted to theGovernment for acceptance 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, ei
35、ther indicated or actual, nor does it commit the 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 Classificat
36、ion of inspection. The inspection requirements specified herein are classified as follows: 1. 2. First article inspection (See 4.3). Quality conformance inspection (see 4.4). 4.3 First article inspection. 4.4 Quality conformance inspection. Sampling for inspection shall be performed in accordance wi
37、th MIL-STD-105, except where otherwise indicated. 4.4.1 Component and material inspection. In accordance with 4.1 above, components and materials shall be tested in accordance with all the requirements of referenced specifications, drawings, and standards unless otherwise excluded, amended, modified
38、, or qualified in this specification or applicable procurement documents. 4.4.2 Examination of the end item.

When the total yardage in the roll. does not exceed 100 yards (91.4m), the entire yardage in the roll shall be examined. When the total yardage in the roll exceeds 100 yards (91.m), only 100 yards (
40、91.4m) shall be examined. Ail defects as defined in Section III of FED-STD-4, which are clearly noticeable at normal inspection distance (3 feet) (0.91m), shall be scored and assigned demerit points as listed in 4.4.2.1.1, except that only the slubs and knots which exceed the limits shown on Sears F
41、abric Defect Scale (see 6.4), “E“ or 3 for slubs and “C“ for knots shall be scored. No linear yard (increments of 1 yard (0.91m) on the measuring device of the .inspection machine) from any one roll within the sample shall be penalized more than 4 points.

43、shipping containers shall be sampled. The lot shall be unacceptable if the points per 100 square yards ( 83.6m2 ) of the total yardage examined exceeds 28 points. The lot sQa11 be unacceptable if the individual points per 100 square yards (83.6m ) of two or more individual rolls exceed? 40 points. I
44、f one roll exceeds the point level per 100 square yards (83.6m ), a second sample, the same size as the final sample, shall be examined only for individual roll quality examination. The lot shall be unacceptable if one or mor? rolls in the second sample exceeds 38 points per 100 square yards (83.611

Point computation for lot quality. and individual roll quality shall be as follows: Total points scored in sample x 3600 Contracted width of cloth (inches) x Total yards inspected = Points per 100 square, yards (83.6m ) 4.4.2.1.1 Demerit points. Demerit points shall be assigned as follows: For
