Abstract: The TFR(Tampered Failure Rate) model was proposed by Bhattacharyya and Soejoeti(1989) for step-stress accelerated life tests. On step-stress completely accelerated test occasions, the paper gives a method of estimating parameters under a normal stress.

Key words: exponential disteribution, TFR model, CE model, step-stress completely accelerated test, normal stress
