Abstract��According to GB/T 4337��2015 and GB/T 24176��2009�� there are three typical fatigue results used in uncertainty evaluation were provided. These are�� i�� fatigue life at a pre-determined stress�� ii�� fatigue strength at a pre-determined life and iii�� the[S-N]curve. The evaluation methods employed are for type A ��those which are evaluated by the statistical method�� and type B. The application of evaluation methods were displayed by the example with testing data according to fatigue life at a pre-determined stress�� fatigue strength at a pre-determined life and[S-N]curve. At the same time schematic figure for the expanded uncertainty for predicted life value was offered.
