3.8.1 Ballistics. Initiators loaded with accepted pyrotechnic components (II-A pellets and PVU-
1/A ignition device) 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.
3.8.1.1 Initiation. The initiator shall be fired by a source delivering an output pressure of 700 +25, -
0 pounds per square inch gage (psig) at 70 ± 5°F.
3.8.2 Misfires. There shall be no misfires.
3.8.3 Mechanical failures. The initiator shall function without mechanical failure (see 6.5.2).
