Vibration, Shock and Intense Noise Testing for Reliability

Avionic units (particularly those used aboard high-performance aircraft and missiles) should be tested with vibration, shock, and intense noise. The goal of such laboratory testing is to identify weaknesses so that corrective steps toward high reliability can be taken. Test equipments and their applications to simulating pontentially damaging environments are considered. These subjects are noteworthy because of the 1977 revision of MIL-STD-781C.
