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

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
