2.4 Order of precedence. In the event of a conflict between the text of this document and the
references cited herein (except for related specification sheets), 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.
3.2 Conformance to documents. The M104 Initiator covered by this specification shall be
manufactured in accordance with DL10551446.
3.3 Components.
3.3.1 Primary components. For the purpose of this specification, propellant, II-A Bi-convex pellets
(MIL-P-46994) is defined as a primary component. Only primary components from a single lot shall be
used in a production lot of initiators; however, one primary component production lot may be used in more
than one initiator production lot.
3.3.2 Component parts. All component parts shall meet the applicable requirements of MIL-DTL-
50375 prior to assembly.
3.4 Breakaway torque. The female body and male body of each assembled initiator shall withstand
a breakaway torque application of 400 inch-pounds without loosening or deformation (see 4.3.1).
3.5 Residual magnetism. The initiator shall not deflect the indicator of the compass more than five
degrees in either direction (see 4.3.2).
3.6 Radiographic examination. Each initiator assembly shall be radiographically examined for
defects (see 4.3.3).
3.7 Leak test. Each assembled initiator shall exhibit no air leakage greater than 1 x 10-4 standard
cubic centimeters per second (see 4.3.4) at a 14.7 psia pressure differential.
3.8 Functional.
3.8.1 Ballistics. Initiators loaded with accepted pyrotechnic components (II-A pellets) and
temperature conditioned shall produce pressure values specified in table I. Pressure values shall be
recorded in a 6.5-cubic-inch closed bomb, Drawing 838AS163.
