Electro-Explosive Device Pulse Reflection Checkout Technique

Abstract

The pulse reflection test method permits a more comprehensive electrical check of an EBW ordnance device than can be obtained by the ac and dc continuity check methods currently in use throughout the industry. Pulse reflection testing is a specialized application of time domain reflectometry. Laboratory tests performed on a triple-scale EBW Test Model showed that waveforms produced by imposing various test conditions are definite and repeatable, and that these waveforms can be interpreted so as to determine whether an EBW device is electrically operable or defective.
