The static ring components require a long period of time to do accelerated storage test. To overcome this difficulty, a step-down-stress Accelerated Life Test (ALT) method was introduced in this paper. The principle and flow of this method were presented. Combined with Arrhenius model, maximum likelihood estimation was applied to evaluate storage life reliability of the product. Finally, according to the results of accelerated storage test, the storage life of static ring components was determined in a shorter test time.
