With this in mind a question occurs whether these samples may be loaded again. This paper includes tests on steel S355J2+C for finite fatigue life, as well as for infinite fatigue life. The samples that did not break in the staircase method were repeatedly tested at higher load. The results obtained were compared with the results obtained on samples that had not been previously loaded. An impact of the previous tests was identified. With the use of statistic calculations, it is possible for adjust for the obtained values of cycle numbers, so that they correspond to the values of samples not previously loaded. The results obtained may be accepted as satisfactory.
