Unless otherwise specified in the contract or purchase order, the contractor is responsible for the perf
22、ormance 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 or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapprove
23、d 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 supplies and services conform to prescribed requirements. * 4.1.1 Responsibility for compliance. All items shall meet all req
24、uirements 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 of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that a
25、ll products 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 defectiv
26、e material, either indicated or actual, nor does it commit the Government to accept defective material. 4.1.2 Certificates of compliance. When certificates of compliance are submitted, the Government reserves the right to inspect such items to determine the validity of the certification. * 4.2 Class
27、ification of inspections. The inspection requirements specified herein are classified as follows: a. b. First article inspection (see 4.3). Quality conformance inspection (see 4.4). * 4.3 First article inspection. When a first article is required (see 3.1 and 6.2), it shall be examined for the defec
28、ts specified in 4.4.2 and shall be tested for the characteristics specified in 4.4.3. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,- MIL-T-43709B 3 9999906 0463794 5 W 4.4 Quality conformance inspection.
