About Trends in the Strategy of Development Accelerated Reliability and Durability Testing Technology
Accelerated Life Testing (ALT) is now the primary source for obtaining initial information for predicting a product's reliability, durability and maintainability. This paper shows that such testing fails to offer relevant information, because the product's degradation process in testing conditions differs substantially from the product's degradation process under field conditions. Consequently, the mean-time-to-failure is skewed, resulting in problems with recalls, reliability, and maintainability. Accelerated reliability and durability testing technology (ART/ADT) is an approach to the problem which can improve the situation with more accurate prediction of reliability and durability.
