This paper demonstrates the results of the analysis of the current practical situation in product reliability and durability as well as accelerated stress testing development. High stress testing is now the basic source for obtaining initial information to provide a prediction of a product's reliability and durability. This paper shows that this testing cannot offer information for the accurate prediction of reliability and durability, because the product degradation process during the testing differs from the product degradation process during the actual field situation. As a result, the time to failures also differs.
