标准范围

ISO 1352:2011规定了在不故意引入应力集中的情况下，对金属试样进行扭转、恒定振幅、名义弹性应力疲劳试验的条件。试验在空气中的环境温度（理想情况下为10°C至35°C）下进行，方法是围绕试样纵轴向试样施加纯电偶。虽然ISO 1352:2011中描述了圆形截面和管状截面试样的形式、制备和测试，但不包括部件和其他特殊类型的测试。同样，在恒定振幅角位移控制下进行的低周扭转疲劳试验也被排除在外，该试验会导致几千次循环失效。

ISO 1352:2011 specifies the conditions for performing torsional, constant-amplitude, nominally elastic stress fatigue tests on metallic specimens without deliberately introducing stress concentrations. The tests are carried out at ambient temperature (ideally at between 10 °C and 35 °C) in air by applying a pure couple to the specimen about its longitudinal axis.While the form, preparation and testing of specimens of circular cross-section and tubular cross-section are described in ISO 1352:2011, component and other specialized types of testing are not included. Similarly, low-cycle torsional fatigue tests carried out under constant-amplitude angular displacement control, which lead to failure in a few thousand cycles, are also excluded.
