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
27、 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 in this specifi
28、cation where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements (see 6.2). 4.1.1 Responsibility for compliance. Ali items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the c
29、ontractors overall inspection system or quality program. The absence 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 con
30、tract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements; however, this does not 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-T-45499C 9999906 1854492 477 MIL-T-45499

Reference shall be made to MIL-STD-109 to define the quality assurance terms used. 4.1.3 Inspections.
32、Inspections shall be in accordance with MIL-A-2550 and MIL-STD-453. 4.2 Inspection provisions. 4.2.1 Lot. 4.2.1.1 Submission of product. Unless otherwise specified by the contracting activity, formation, and identification of lots shall be in accordance with MIL-STD-105. 4.2.1.2 Size of lot. The pro
33、duction lot size shall be as specified in the contract (see 6.2). 4.2.2 Examination. One hundred percent examination shall be performed for all critical defects. Examination for major and minor defects shall be performed in accordance with the classification of defects. Four power (4x) magnification
34、 may be used for inspection of such defects as burr and foreign matter. 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. 4.2.2.1 Cartr
