COMBINED-ENVIRONMENT TESTING OF SHIPBOARD ELECTRONIC EQUIPMENT.

Abstract

Lack of improvement in reliability of operational shipboard electronic equipment over some years has led to an investigation of present test methods. This report shows that the method presently used for subjecting electronic equipment to environments in sequence fails to simulate actual environmental conditions and to subject the equipment to the synergistic (interacting) effects of the environment. A combined-environment test consisting of 27 combinations of temperature, humidity, and vibration is applied to several specimens of an if/am amplifier module to verify the presence of synergistic effects, and these effects are shown to contribute to deterioration in performance. The development of a standard combined-environment test procedure is recommended. (Author)
