The most non-parametric homogeneity tests from censored data are powerful against scale alternatives. We propose several tests which are powerful for scale-shape alternatives. They do well also in situations when reliability functions cross or have common points. Power of the tests is investigated.

We give also non-parametric goodness-of-fit tests for the most used acceelerated life models used in survival regression and accelerated life testing. In particular, tests for accelerated failure time and proportional hazards models against various alternatives are given. Several plans of experiments are discussed.
