MIL-DTL-50699B
3. REQUIREMENTS
3.1 First article. When specified (see 6.2), a sample shall be subjected to first article inspection
(see 6.4) in accordance with 4.4.
3.2 Conformance to documents. The JAU-2/A25 initiator covered by this specification shall be
manufactured in accordance with DL11731494.
3.3 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.
3.4 Components.
3.4.1 Primary components. For the purpose of this specification, the PVU-1/A Ignition Device
(Drawing 851AS110) 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.
3.4.2 Ignition device. The ignition device shall conform to the applicable drawing and reference
specification. Prior to assembly into an initiator, the ignition device shall be visually examined in
accordance with 4.5.2.5 and radiographically examined for defects as specified in 4.6.6.1. The ignition
device shall be manufactured within 2 years of assembly into the ignition device retainer (11738408) or
recertified within 12 months of assembly into the ignition device retainer.
3.4.3 Ignition device sensitivity. The PVU-1/A Ignition Device, when assembled and crimped
into an ignition device retainer (Drawing 11738408), shall fire when drop tested at an energy level of 25.48
inch ounces, maximum (see 4.5.3.6).
3.4.4 Leak test. Each retainer and ignition device assembly, Drawing 11738409, and the M104
propellant actuated initiator, P/N 10551446, shall withstand 14 psi internal-external pressure differential
with a maximum permissible leak rate of 1 x 10-4 cubic centimeters per second of air (see 4.5.3.5).
3.5 Breakaway torque. Each threaded joint of the assembled initiator shall withstand a breakaway
torque application of 400 inch-pounds without loosening or deformation (see 4.5.3.4).
3.6 Residual magnetism. The initiator shall not deflect the indicator of the compass more than five
degrees in either direction (see 4.5.3.3).
3.7 Radiographic examination. Each ignition device assembly, retainer and ignition device
assembly, and initiator assembly shall be radiographically examined for defects (see 4.6.6).
3.8 Functional.
