Unless otherwise Specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as other

33、wise 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 Government reserves the right to perform any of the inspections set forth i

34、n the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-872b1 83 99999Ob 0501808 5 MIL-(3-87261 4.1.1 Responsibility f

35、or compliance. All items shall meet all requirements of sections 3 and 6. 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 contract

36、or of the responsibility of insuring that all products or supplies submitted 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 compliance to requirements, however, this does n

37、ot authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept 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 th

38、e validity of the certification. 4.2 Classification of inspections. The inspection requirements specified herein are classified as b follows: a. First article inspection (see 4.4). b. Quality conformance inspection (see 4.6) 4 4.3 Inspection conditions. Unless otherwise specified, all inspections sh

39、all be performed in accordance with the test conditions specified in sections 4.4,4.6 and 4.6 of this specification. 4.4 First article inspection. The first article inspection shall consist of specified examinations and tests performed on samples of chemical protective laminated cloth and activated

40、carbon spheres to determine that the production item conforms to the requirements of this specification. 4.4.1 First article samples. Unless otherwise specified, as soon as practical after the award of the contract or order, the manufacturer shall submit five linear yards of the chemical protective

41、laminated cloth and 1.0 kilogram of the activated carbon spheres for subjection to the examinations and tests specified in 4.4.2. The samples shall be representative of the construction, workmanship, components and materials to be used during production. 4.4.2 First article tests. The first article

42、samples shall be subjected to tests specified in section 3 in accordance with methods specified in 4.7 of this specification. 4.5 Quality Conformance Inspection. Sampling for inspection shall be performed in accordance with MIGSTD-106, except where otherwise indicated hereinafter. 4.6.1 Component an

43、d material inspection. In accordance with 4.1 above, components and materials shall be tested in accordance with all the requirements or referenced specifications, drawings, and standards, unless otherwise excluded, amended, modified or qualified in this specification or applicable purchase document

Examination of the end item shall be in accordance with the provisions of 4.6.2.1 through 4.6.2.2.2. . 7 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-87261 83 999990b 0501809 7 MIL-C-87261 4.5.2.1 Yard-b

45、y-yard examination. Each roll in the sample shall be examined on the outer layer (woven) and inner layer (knit) sides and visual defects as defined herein shall be classified as listed in table N. All defects found shall be counted regardless of their proximity one to another except where two or mor

46、e defects represent a single local condition of the cloth, in which case only the more serious defect shall be counted, Acontinuous defect shall be counted as one sample unit for each lengthwise yard or fraction thereof in which it occurs. The sample unit for this examination shall be one linear yar

47、d. The sample size shall be in accordance with Inspection Level II of MIGSTD-106. The Acceptable Quality Level (AQL) shall be 4.0 major defects and 10.0 minor defects per100 units (yards). The total size shall be expressed in units of one linear yard. An approximate equal number of yards shall be ex

48、amined from each roll selected for yard by yard examination. TABLE Il? End item inspection. - 1/ Classification Defect Major Minor Part A - Outer layer (woven cloth) side 1.
