Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other faci

27、lities 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 this specification where such inspections are deetned necessary to ensure supplies and services

28、conform to prescribed requirements. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-1-82877 13 9999906 0511577 7 MILI-82877 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The inspection sd forth

29、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 all products or supplies submitted to the Government for

30、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, either indicated or actual, nor does it comm

31、it the Goverriment to accept defective material. 4.2 Classification of hspa3ion.s. 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 Inspection conditions. Unless otherwise specified (see 6.

32、2), ail inspections shall be performed as specified in the applicable methods of inspection specified in 4.6, 4.4 First article inspection. The first article sample shall consist of 75 ignition elements which . have been produced using the same materiais, equipment, processes and procedures and the

33、same source of supply as will be used in regular production. First article inspection shail be performed at a facility designated in the contract or order (see 6.2). First article inspection shall be performed on 61 samples as specified in table i and 14 samples shall be retained for investigative p

34、urposes. Failure of any ignition element shall be cause for rejection of the first article sample. TABLE I. First article insDect ion.
