31、ied 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 otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for t
32、he 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 in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed
33、requirements (see 6.2). 4.1.1 Responsibility for compliance. Ail items shall meet all requirements 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 th
34、e 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 requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain c
35、onformance to requirements; however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Quality assurance terms and definitions. Reference shall be made to MIL-STD-109 to define the
36、quality assurance terms used. 4.1.3 Inspections.

The inspection requi
37、rements specified herein are classified as follows: a. First article inspection (see 4.4) b. Quality conformance inspection (see 4.5) c. Remanufacture program inspections (see 4.6) 4.3 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be performed under the following
38、 conditions: a. b. Altitude: sea level c. d. Atmospheric pressure: 14.7 psi Temperature: room ambient (68 to 77F) Humidity: 50 percent relative, maximum 4.4 First article inspection. At the beginning of regular production, the contractor shall submit an initial production sample to a Government appr
39、oved facility for evaluation. The sample shall consist of five metal parts assemblies, nine sets of unassembled parts, and one set of unassembled parts without plating or final protective finish. The sample shall be manufactured in the same manner, using the same materials, equipment, processes, and
40、 procedures as used in regular production. All parts and materiais, including packaging and packing, must be the same as will be used for regular production and shall be obtained from the same source of supply. After inspection and provisional acceptance at source, the first article sample shall be
41、inspected for all requirements of the drawings and specifications. The Government reserves the right to require new first article samples until an acceptable sample is submitted (see 6.3). - 4.5 Quality conformance inspection. 4.5.1 Lot. 4.5.1.1 Submission of product. Unless otherwise specified by t
42、he contracting activity, formation and identification of lots shall be in accordance with MIL-STD-105. 4.5.1.2 Size of lot. The production lot size shall be as specified in the contract. 4.5.2 Examination. One hundred percent examination shall be performed for all critical defects. Examination for m
43、ajor and minor defects shall be performed on a defect basis in accordance with the classification of defects. Four power (4x) magnification may be used in performing visual examination for such defects as burr and foreign matter. Inspection for rubber O-rings shall be in accordance with MIL-STD-413.
44、 When compliance with the applicable requirement is in doubt as a result of visual examination, the characteristic shall be measured or gaged to determine acceptability. All nonconforming material shall be rejected. 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without licen
