22、herwise 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 or any other facilities

23、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 the specification where such inspections are deemed necessary to ensure supplies and services conform t

24、o the prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The inspections set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requiremen

25、ts 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 parts of manufacturing operations, is an acceptable practice to as

26、certain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 0 4.1.2 Classification of inspections.

32、tion have been revised sufficiently to affect the character of the product. (3) When deemed necessary to determine that the product continues to meet all of the specification requirements. (4) A major change in the product has occurred (see 6.3.2). 4.2.4 Rejection. If any sample fails to comply with

33、 any of the applicable requirements, the first article quantity shall be rejected. The Government reserves the right to terminate its inspections upon any failure of a sample to comply with any of the stated requirements. 4.3 Quality conformance inspection. 4.3.1 Inspection lot formation. A lot shal
