I 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for

26、inspection. Unless otherwise specified in the contract or purchase order, the con- tractor is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities su

27、itable for the performance of the inspection requirements specified herein, unless disapproved by the Govern- ment. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform t

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

29、 in the specification shall not relieve the con- tractor of the responsibility of assuring that all products or supplies submitted to the Government for ac- ceptance comply with all requirements of the contract. Sampling in quality conformance does not authorize submission of known defective materia

30、l, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.2 Classification of inspections. The inspection requirements specified herein are classified as follows: a. First article inspection (see 4.4) b. Quality conformance inspection (see 4.5). 4.3 Insp

31、ection conditions. Unless otherwise specified (see 6.2), all inspections shall be performed as specified in the applicable test method of 4.6. 4.4 First article inspection. First article inspection shall be performed after award of contract and prior to production by a facility designated in the con

32、tract or order (see 6.2). A first article sample acceptable for environmental and function testing shall be considered as a sample that has met the requirements of 3.2 through 3.7.3 and 3.10 of this specification. First article inspection shall be performed on sample units which have been produced u

33、sing the same materials, equipment, processes and procedures as will be used in regular production. All parts and materials, including packaging and packing shall be the same as used for regular production and shall be from the intended sources of supply. .I I Licensed by Information Handling Servic
