Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection r
32、equirements (examinations and tests) as specified 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 Go
33、vernment reserves the right to perform any of the inspections set forth in this 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
34、. 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 products or supplies submi
35、tted to the Government for acceptance 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
36、or actual, nor does it commit the Government to accept defective material. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-41824C 4 m 7777706 0146707 I? R MIL-C-41824C 4.1.2 Responsibility or dimensional requirements. Unless otherwise speci-
37、fied in the contract or purchase order, the contractor is responsible for ensuring that all specified dimensions have been met. When dimensions cannot be examined on the end item, inspection shall be made at any point, or at all points in the manufacturing process necessary to ensure compliance with
38、 all dimensional requirements. 4.1.3 Certificates of compliance. When certificates of compliance are submitted, the Government reserves the right to inspect such items to determine the validity of the certification. 4.2 Classification of inspections. The inspection requirements specified herein are
39、classified as follows: a. First article inspection (see 4.3). b. Quality conformance inspection (see 4.4). 4.3 First article inspection. When a first article is required (see 3.1 and 6.21, it shall be examined for the defects specified in 4.4.3 and 4.4.4. 4.4 Quality conformance inspection. Unless o
40、therwise specified, sampling for inspection shall be performed in accordance with MIL-STD-105. 4.4.1 Component and material inspection. In accordance with 4.1, components and materials shall be inspected in accordance with all the requirements of referenced documents unless otherwise excluded, amend
41、ed, modified, or qualified in this specification or applicable purchase document. 4.4.1.1 Component and material certification. A certificate of compliance may be acceptable as evidence that the laminated cloth characteristics listed in table I conform to the specified requirements when tested by th
42、e specified methods. The methods of testing specified in FED-STD-191, wherever applicable, and as listed in table I shall be followed. TABLE I.
