The process section of test rate of the metal material tensile test at room temperature was introduced. The relationship between the stress rate and strain rate, the relationship between strain rate over the parallel length and strain rate, the relationship between stress rate and strain rate over the parallel length , and the relationship between crosshead separation rate and strain rate over the parallel length were discussed. And some suggestions of the setting for tensile test rate were put forward. According to the existing rate control methods of the testing machine and the measuring requirement of the material performance index, the suitable rate control mode was selected. According to the selected rate control mode and the yield point of the material, the test rate conversion point was correctly determined.
