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 unle ss specific approval in writing covering a
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 Hydrostatic pressure. The initiator chamber and cap shall withstand a hydrostatic pressure of
5500 to 6500 pounds per square inch (psi) for 15 seconds, minimum, without deformation or mechanical
failure (see 6.3.1).
3.3 Firing pin release. The firing pin of the assembled initiator, less safety pin, 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pounds has withdrawn the initiator pin 3/4 inch, maximum (see 4.4.4.2).
3.4 Initiator pin security. The initiator pin of the assembled initiator, less cartridge retainer 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 4.4.4.3).
3.5 Protective finish. Protective finish shall be in accordance with the applicable specifications and
drawings and shall apply to all surfaces of the component, regardless of configuration. Remanufactured
exterior components shall have the existing protective finish stripped and the specified protective finish
reapplied (see 6.3.2).
3.6 Residual magnetism. The metal parts assembly shall not deflect the indicator of the compass
more than five degrees in either direction (see 4.5.5).
3.7 Metal parts assembly. Parts shall be combined to produce an assembly which conforms to the
requirements of the metal parts assembly drawing. All threaded joints shall be assembled handtight.
3.7.1 Integrated plant products. When remanufacturing and loading of assembly is performed in
an integrated plant, the metal parts assembly requirement may be waived and the residual magnetism
requirement performed on the loaded assembly only.
3.7.2 Threaded component parts. Class 2A or 2B thread gage shall be used on remanufactured
component parts inspection versus Class 3A or 3B thread gage required on new hardware for initiators.
3.8 Workmanship. Initiators shall be free of cracks, splits, or other defects which might prevent
proper mating with connecting parts or proper functioning of the device.
