leakage. The simulators shall be vibrated in accordance with the
equipment and procedures specified in MIL-STD-810, Method 514.1,

radiographic standards showing the following conditions:
a. One (1) acceptable item (flash tube appears centered in
o u t e r t u b e , i . e . center lines of flash tube and outer tube in line)
snowing disc completely seated within the flash tube and no evidence

c. One (1) unacceptable item showing disc completely out of
phase with flash tube and evidence of powder in outer tube;
d. One (1) unacceptable item showing disc not completely
seated within flash tube and evidence of powder in outer tube.
The above standards and the radiographic technique used shall be
submitted to ARRADCOM, DRDAR-QAT-M, Dover, NJ 07801 for approval
