In order to maintain the operational efficiency and reliability of the missile, designed a high accelerated life test method for missile storage and life-extension. On the basis of reliability theory, based on the principle and characteristics of high accelerated life tests, this paper expounds the high accelerated life test in the application of missile storage life extension test value, through analysis of HALT process, test section and test method, designed the HALT program and gave the failure mode under varied stress and methods for ascertaining product work limit. The experimental results show that this method provides the reference for improving the efficiency of accelerated test.
