Abstract :
Progressive-stress accelerated life testing in which the stress on an unfailed item increases linearly with test time when the time transformation function is a version of the inverse power law is considered. The approach is nonparametric in that not many assumptions are made about life distribution. A testing pattern is introduced, and it is explained how to draw inferences from progressive stress tests. An estimator of life distribution at the usual stress level is proposed
