IEEE 775-1993

This guide identifies factors that should be considered in accelerated aging programs and is intended to be supportive of the aging requirements called for in IEEE Std 323-1983 and its subsidiary standards. This guide presents methodologies for conducting accelerated aging tests in which factors of synergistic interactions, radiation dose-rate effects, oxygen diffusion rates, etc., need to be considered. This guide does not define specific requirements for appropriate radiation exposure sources, selection of specific levels of thermal or radiation exposure, or specific properties to be monitored; nor does it make recommendations for sequencing or combining aging stresses for particular materials or circumstances. For such guidance, one should employ the general guidelines herein, supplemented by considerations of the specific equipment and environment, together with prior experience or the experience of others who have published data on the aging of materials closely related to those in question.
