29、r inspection. 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 otherwise specified in the contract or purchase order, the contractor may use his own o
30、r 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 in this specification where such inspections are deemed necessary to ensure supplie
31、s and services conform to prescribed requirements (see 6.2). 4.1.1 Responsibility for compliance. All 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
32、 of any inspection 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 requirements of the contract. Sampling inspection, as part of manufacturing operations, is
33、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 acceptance of defective material. 4.1.2 Quality assurance terms and definitions. Reference shall
34、be made to MIL-STD-109 to define the quality assurance terms used. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-T-5035bA W 999990b 2853709 475 MIL-T-50356A 4.1.3 Inspections.

35、 conditions. Unless otherwise specified (see 6.2), all inspectams !,ail be performed o under the following conditions: a. Temperature: room ambient (68 to 77F) b. Altitude: sea level c. Humidity: 50 percent relative, maximum d. Atmospheric pressure: 14.7 psi 4.3 Quality conformance inspection. 4.3.1
36、 Lot. 4.3.1.1 Submission of product. Unless otherwise specified by the contracting activity, formation and identification of lots shall be in accordance with MIL-STD-105. 4.3.1.2 Size of lot. For the purpose of identification and shipment, the shipping lots of metal parts assemblies shall consist of
37、 1200 assemblies, maximum, provided the homogeneity requirements of inspection lots have been retained. 4.3.2 Examination. On reprocessed and new parts, one hundred percent examination shall be performed for all critical defects. Examination for major and minor defects shall be performed on a defect
38、 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 0- rings shall be in accordance with MIL-STD-413. When compliance with the applicable requirement is
39、0 in doubt as a result of visual examination, the characteristic shall be measured or gaged to determine acceptability. All nonconforming material shall be rejected. I 4.3.2.1 Examination of reclaimed parts. Examination of reusable parts, which require no reprocessing, shall be limited to inspection
40、 of defects that require visual type inspection. One hundred percent examination shall be performed for all such defects. All nonconforming parts shall be reprocessed or rejected.
