3.5.2 Leak test. Each assembled cartridge shall exhibit no air leakage greater than 1 x 10 standard
cubic centimeters per second (see 4.7.5) at a 14.7 psia pressure differential.
3.5.3 Vibration. The assembled cartridge shall withstand vibration as prescribed in MIL-STD-810,
Method 514.3, Test Procedure I, Test Condition I 3.2.5 without evidence of any disintegration of the
ignition device, propellant, or igniter, or derangement of any component (see 4.7.7 and 6.2).
3.6 Functional requirements.
3.6.1 Ignition device sensitivity. The ignition device shall fire when drop tested at an energy level of 26
inch-ounces in a sectioned cartridge void of igniter and propellant charge (see 4.7.8.1).
3.6.2 Cartridge performance.
3.6.2.1 Misfires. The cartridge shall not fail to fire.
3.6.2.2 Ballistics. The cartridge, when tested in a M120 initiator shall produce the pressures, delay times
(see 6.6.1), and times to Pmax (see 6.6.2) at temperatures specified in table I (see 4.7.8.2). Pressure values
shall be produced in a one cubic inch pressure station at the end of 15 feet of hose in accordance with
MS-28741-4.
