When product reliability at use conditions is high, accelerated life tests (ALT) are necessary to reduce test time. By testing parts under more severe conditions, the failure time is much lower, so testing can be completed in a reasonable time. Then, the accelerated failure data can be used to predict product reliability at low stress.
