Nondestructive and impulsive testing of electroexplosive devices.

Discussion of NDT techniques and instrumentation developed to demonstrate the quality and normal behavior of 1-W/1-A no-fire electroexplosive devices (EEDs) without firing or degrading the units. Application of these techniques is limited to the bridgewire/explosive/header interface which is considered to be the most critical link in the electroexplosive chain. A certain amount of destructive testing required to determine the sensitivity and output of the EEDs can be accomplished by additional instrumentation that initiates and delivers energy in an impulsive manner with control of pulse width and amplitude.
