Accelerated Reliability/Durability testing (ART/ADT) is an extremely important and quite complicated problem of reliability theory and practice. It is known to be today the most efficient reliability estimation of equipment and systems. The main problems reliability engineer withstands with in connection with the accelerated tests are twofold: 1 How to be sure that we can successfully and appropriately apply the acceleration to the system under observation (SUO) 2 How to handle statistics obtained when the situation is not “clear-cut” This paper is dealing with each of the above questions trying to give a comprehensive organizational and statistical framework for an accelerated Reliability test planning, tracking and decision making. Accurate prediction and control of reliability and durability plays a very important role in the profitability of a product.
