Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations an
29、d 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 the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right
30、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 requirements. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-4.1.1 Responsibility f

The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all product
32、s 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 conformance to requirements, however, this does not authorize submission of known defective material
33、, either indicated or actual, nor does it commit the Government to accept defective material, The inspection set forth in this specification shall 4.1.2 Responsibility for dimensional requirements. Unless otherwise speci- fied in the contract or purchase order, the contractor is responsible for ensu
34、ring that all specified dimensions have been met. When dimensions cannot be examined on the end item, inspection shaIl be made at any point, or at all points in the manufacturing process necessary to assure compliance with all dimensional requirements. 4.2 Classification of inspections. The inspecti
35、on requirements specified herein are classified as follows: a. First article inspection (see 4.3). b. Quality conformance inspection (see 4.4). 4.3 First article inspection. When a first article is required (see 6.2), it shall be examined for the defects specified in 4.4.3 and 4.4.4 and tested as sp
36、ecified in 4.5.2 through 4.5.6, as applicable. 4.4 Quality conformance inspection. Unless otherwise specified, sampling for inspection shall be performed in accordance with MIL-STD-105. 4.4.1 Component and material inspection. In accordance with 4.1, components and materials shall be inspected in ac
37、cordance with all the requirements of referenced documents unless otherwise excluded, amended, modified, or qualified in this specification or applicable purchase document. 4.4,2 In-process inspection. 4.4.2.1 In-process examination. In-process examination shall be made to establish conformance to t
