The accelerated life test theories based on Arrhenius , Norris-Landzberg and Peck models were briefly introduced .Targeting the reliability features and the difficulties of accelerated life tests , an accelerated stress test method for space-electronic equipments was proposed based on a perform-ance degradation model .In the end , application examples were given to verify the proposed method . This provides a brand new idea for the reduction of uncertainties in the test design stage .
