Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requir
27、ements (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 Governm
28、ent reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to assure supplies and service conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The
29、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 re1 ieve the contractor of the responsi bi 1 i ty of ensuring that all products or supplies submit
30、ted 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 o
31、r actual, nor does it commit the Government to acceptance of the defective material. 4.1.2 Test equipment and inspection facilities. The manufacturer shall insure that test and inspection facilities of sufficient accuracy, quality and quantity are established- and maintained to permit performance of
32、- required inspections. 4.2 Classification of inspections. The inspection requirements specified hereinare classified as follows: Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-29567 3 W 999990b 0389532 - 9 W MIL-C-29567 a.

33、ction. The first article inspection consists of examinations and tests performed on samples which are representative of the production item after award of a contract to determine that the production item conforms to the requirements of this specification (see 4.4). b. Quality conformance inspection.
34、 Quality conformance inspection consists of examinations and tests performed on the individual products or lots to determine comformance of the products or lots with the requirements set forth in this specification (see 4.5) * 4.3 Inspection conditions. Unless otherwise specified herein, all testing
35、 shall be performed under standard atmospheric conditions and performed on specimens in moisture equilibrium under standard atmospheric conditions specified in FED-STD-191 or ASTM as applicable. - P 4.4 First Article. 4.4.1 First article inspection.

When a contractor is in continuous production of this laminated cloth from contract to contract, submission of further first article inspection samples on the new contract, may be waived at the discretion of acquiring
38、 activity (see 6.2.1). Approval of the first article inspection samples or the waiving of the first article inspection does not waive the requirements for performing the quality conformance inspection. first article inspection samples shall be furnished to the Government as directed by the contracti

45、roximity to each other except where two or more of the same defects represent a single local condition occurring within one square yard of the cloth, in which case only one defect shall be counted. A continuous defect shall be counted as one-defect for each warpwise yard or fraction thereof in which
