REQUIREMENTS 3,l Materials, All materiais used in the manufacture of the initiators shall conform to the specifications referred to on the respective drawings unless specific approval in writing covering a departure has been obtained from the cognizant Navy design activity prior to manufacture
13、. When alternate materials or methods of manufacture are specified on the drawings, the bidders selections shall be clearly stated in the proposal. 3.2 Components. 32.1 Primary components. For the purpose of this specification, the Ml55 delay cartridge (Drawing 10521632) is defrned as a primary comp
14、onent. Only primary components from a single lot shall be used in a production lot of initiators. One primary component production lot may be used in more than one initiator production lot. 3.2.2 Component parts. All component parts shall meet the applicable requirements of MIL-1-14857 or MIL- 14029

The inspection set forth in this specific
24、ation 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 acceptance compl
25、y with all requirements of the contract. Sampling inspection, as part Df 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 commit the Governmen
26、t to accept defective material. 4.1.2 Quaty assurance terms and definitions. Reference shall be made to MIL-STD-109 to define the quality assurance terms used. 4.1.3 Inspection. Inspection shall be in accordance with MIL-A-2550 and MIL-STD-453. 4.2 Inspection provisions. 4.2.1 Lot. 4.2.1.1 Submissio
27、n of product. Unless otherwise specified by the contracting activity, formation and identification of lots shall be in accordance with MIL-STD-105. 4.2.1.2 Size of lot. A lot shall consist of an identifiable group of assembled initiators containing metal parts assemblies produced by a homogeneous pr
28、ocess and loaded with one lot of accepted cartridges. 4.2.2 Examination. One-hundred percent examination shall be performed for all critical defects. Examination for major and minor defects shall be pehrmed in accordance with the classification of defects. Four power (4X) magnification may be used f
29、or inspection of such defects as burr and foreign matter. When compliance with the applicable requirement is in doubt as a result of visual examination, the characteristic shall be measured or gaged to determine acceptability. All nonconforming material shall be rejected. 4.2.2.1 Cartridge, Initiato
