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. Inspections shall be in accordance with MIL-A-2550. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-R-82879 999990b 1970373 720 MIL-R-82879 4.2 Classification of 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
