The Government reserves the right to perform any of the inspections set forth in this Specification where such inspection

34、s are deemed necessary to ensure supplies and services conform to prescribed requirements. * 4.1.1 Responsibility for compliance. All items must meet all requirements of Section 3 and 5. The inspection set forth in this Specification shall become a part of the contractors overall inspection system o

35、r quality program. requirements in the Specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all require- ments of the contract. Sampling inspection, as part of manufacturing operations, i

36、s 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 Government to accept defective material. The absence of any inspection 4.1.2 Certificate of compliance. Where

37、 certificates of compliance are submitted, the Government reserves the right to check the tests of such items to determine the validity of the certification. 4.2 Classification of inspection. The inspection requirements specified herein are classified as follows: 1. First article inspection (see 4.3

38、). 2. Quality conformance inspection (see 4.4). 4.3 First article inspection. When required (see 6.2), the first article submitted in accordance with 3.3 shall be visually inspected for color, finish and appearance and shall be tested for chemical and physical properties in accordance with the appli

39、cable methods specified in 4.5. 4.4 Qualitv conformance inspection. Sampling for inspection shall be performed in accordance with MIL-STD-105, except where otherwise indicated. 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-B-87002C 4.4.1 Comp

42、assified in accordance with Table II. The defects found during this examination shall be counted regardless of their proximity to each other, except where two or more defects represent a single local condition of the batting, in which case only the more serious defect shall be counted. A continuous

43、defect shall be counted as one defect for each lengthwise yard or fraction thereof in which it occurs. The sample unit shall be one linear yard of batting. The sample size shall be based upon inspection Level II of MIL-STD-105. The sample size and the lot size shall be expressed in units of one yard

44、 each. The number of rolls from which the sample is to be selected shall be in accordance with Table III. The Acceptable Quality Level (AQL) shall be 2.5 major and 6.5 total defects (major and minor combined) per 100 units (yards). * 4.4.2.1 Intermediate inspection. The unquilted needled batting sha
