2.4 Order of precedence. In the event of a conflict between the text of this document and the references
cited herein, the text of this document takes precedence. Nothing in this document, 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 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. The remanufactured metal parts assembly shall contain a new safety pin, initiator spring, O-rings,
and seal.
3.2 Hydrostatic pressure. The initiator cap, chamber, and plug, simulating the firing pin housing (without a
firing pin pin hole but with an O-ring), shall withstand an internal hydrostatic pressure of 5500 to 6500
pounds per square inch (psi) for 15 seconds minimum, without deformation or mechanical failure (see 6.4.1).
3.3 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
6.4.2).
3.4 Residual magnetism. The metal parts assembly shall not deflect the indicator of the compass more than
5 degrees in either direction (see 4.5.5).
3.5 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withdrawn the initiator pin 3/4 inches, maximum.
3.6 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.
3.6.1 Initiator pin. Check safety pin groove length for 0.118 ± 0.010 inch dimension (100 percent
inspection.)
3.7 Metal parts assembly. Parts shall be combined to produce an assembly that 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 the 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 component part inspection
versus class 3A or 3B thread gage required on remanufactured hardware for initiators.
