适用范围:1.1 This standard specifies the conditions for carrying out torsional stress fatigue tests on test pieces having a nominal diameter between 5 and 12.5 mm without deliberately introduced stress concentrations. The tests are carried out at room temperature in air, by applying to the test piece a pure couple about its longitudinal axis.1.2 The form, preparation and testing of test pieces of circular cross-section are specified but component testing and other specialized form of tests are not included. Similarly, high strain torsional fatigue tests, which lead to failure in a few thousand cycles, are also excluded.
