3.5.1 Radiographic examination. Each cartridge assembly shall be radiographically examined for defects
(see 4.7.4).
3.5.2 Air tightness. Each assembled cartridge shall exhibit no air leakage greater than 1 x 10-4 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 1-3.2.5 without evidence of any disintegration of the
Ignition Device, propellant, or igniter, or derangement of any component (see 4.7.6 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 59
inch-ounces in a sectioned cartridge void of igniter and propellant charge (see 4.7.7.1).
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 closed bomb (Drawing 5184857), shall produce the
pressures and ignition delay at temperatures specified in table I (see 4.7.7.2, 6.6.1, and 6.6.2).
