Pyroshock Testing

Environment Associates Inc. (Environment Associates)

The purpose of Pyroshock (pyrotechnic shock) testing is to simulate the high-frequency, high-magnitude shock pulse experienced by an explosive event (such as an impact on a military tank or an explosive deployment charge). Pyroshock testing can expose failures in electronic components that are sensitive to high-frequency pyroshock energy. Common failures include: relay and crystal oscillator chatter, detachment of larger components from the circuit board, hard failures of small circuit components, and the dislodging of contaminants, which cause short circuits. Severe damage to crucial components used in space or in the military can produce critical results, such as loss of life, due to malfunction.
