Two comparable sets of constant-force small punch tests and relevant conventional creep tests on P91 steel were performed at temperatures from 823 to 873 K. The experimental results were analyzed using various parametric approaches (Larsson-Miller, Fisher-Dorn, etc.) very well-known from conventional creep testing. It is shown that the methods based on time-temperature parameter can be used also for a description of small punch test data. The best description can be achieved with the Sud-Aviation parameter.
