however, supersedes applicable laws and regulations unless a specific exemption has been obtained.
3. REQUIREMENTS
3.1 Materials. All materials used in the manufacture of the initiators shall conform to the specifications referred to on the respective drawings unless specific approval in writing coveringa departure therefrom has been obtained from the cognizant Navy design activity prior to manufacture. When alternate materials or methods of manufacture are specified on the drawings, the bidder's selections shall be clearly stated in the proposal.
3.2 Components.
3.2.1 Primary components. For the purpose of this specification, the M93 delay cartridge (Drawing8593312)isdefinedasaprimarycomponent. Onlyprimarycomponentsfromasinglelot shallbeusedinaproductionlotofinitiators;however,oneprimarycomponentproductionlotmay be used in more than one initiator production lot.
3.2.2 Component parts. AllcomponentpartsshallmeettheapplicablerequirementsofMIL-I-
14083 or MIL-I-60515 prior to assembly.
3.3 Breakaway torque. The chamber and cap of each assembled initiator shall withstand a breakaway torque application of 400 inch-pounds without loosening or deformation (see 4.3.1).
3.4 Residual magnetism. The initiator shall not deflect the indicator of the compass more than five degrees in either direction (see 4.3.2).
3.5 Firing pin release. The firing pin of the assembled initiator, less safety pin, cartridge, cartridge retainer, and chamber shall release from the cocked position when the application of an axial load of 20 to 35 pounds has withdrawn the initiator pin 3/4 inch, maximum (see 4.2.3.3).
3.6 Initiator pin security. The initiator pin of the assembled initiator, less cartridge, cartridgeretainer, and chamber shall not withdraw beyond the safety pin when subjected to an axial load of 200 to 220 pounds. Application of the load shall cause no deformation of the safety pin (see 4.2.3.4).
3.7 Radiographic examination. Each initiator assembly shall be radiographically examined for defects (see 4.3.5).
3.8 Functional.
3.8.1 Ballistics. Initiators loaded with cartridges from one accepted lot and temperature conditioned shall perform within the pressure values and delay times (see 6.4.1) specified in
