TOP-5-2-521, TEST OPERATIONS PROCEDURE: PYROTECHNIC SHOCK TEST PROCEDURES (20-NOV-2007)., This TOP provides guidance for the laboratory simulation of pyrotechnic shock tests via resonant fixtures. The pyrotechnic event is characterized by short transient excitations (less than 4 msec) of high amplitude (3000 g’s) and high frequencies (10 kHz). The transients are typically induced by the activation of missile ordnance components such as explosive bolts, cable cutters, pyrovalves, flexible linear shape charges, and primer cords. This document describes instrumentation, test fixture design, and data collection and processing procedures required to achieve a successful test program. The focus will be on metal to metal impact testing of resonant fixtures tuned to the appropriate test specification.
