单点疲劳试验法适用于金属材料构件在室温、高温或腐蚀空气中旋转弯曲载荷条件下服役的情况。该种方法在试样数量受限制的情况下，可近似测定疲劳曲线并粗略估计疲劳极限。试验所需的疲劳试验机一般为弯曲疲劳试验机和拉压试验机。
The single point fatigue test method is suitable for the service of metal components under rotating bending load at room temperature, high temperature or corrosive air. This method can approximately measure the fatigue curve and roughly estimate the fatigue limit when the number of specimens is limited. The fatigue testing machine needed for testing is generally bending fatigue testing machine and tension-compression testing machine.
