The test apparatus shall be situated in an armored cubicle equipped with a six volt electrical lins controlled by .an external firing switch. B
22、efore firing each detonator measure the diameter of the Bolder (Si( 12316.5) in at least two places and Pecord the largest value. Insert each detonator in a measured holder and mount it in the test apparatus described on LD 185941. Fire the detonator using a Primer Mk 112 Mod O (LD 166550). After fi
23、ring repeat the diameter measurements of the holder. Again measure in at least two places and record the largest measurement. The difference in the holder diameter as measured before and after firing is the expansion of the holder ano is the value “X“ in inches used on NAVORD Form i844C (New 6/51),
24、In this test no holder shall be reused. 5.
