ISO 5393:2017规定了用于安装螺纹紧固件的电动装配工具（在整个文件中称为“工具”）的实验室性能测试方法。ISO 5393:2017提供了一种测量扭矩重复性（散射）的方法-在本文件规定的扭矩率范围内，-在制造商规定的扭矩调整范围内，以及-在制造商规定的多个运行周期内。ISO 5393:2017提供了一种测量内置扭矩测量系统精度的方法，该系统适用于包含此类特征的工具。见附件E。ISO 5393:2017给出了关于设备参数、测试内容以及如何评估和展示测试数据的说明。ISO 5393:2017适用于工具-任何电源，如气动、液压和电动，包括电池供电，-以通常连续的方式施加扭矩，以及-在0.5 Nm至2000 Nm的扭矩范围内。在该范围之外，如果试验报告中记录了修改，则可以修改试验方法。ISO 5393:2017不适用于-冲击或脉冲扳手，-棘轮扳手或带棘轮离合器的扳手，以及-以不连续增量推进紧固件，克服每次增量静摩擦的其他工具。ISO 5393:2017允许在任何试验扭矩水平下进行试验；然而，为了尽量减少各种试验扭矩水平所需的试验接头数量，附录a中提供了一份首选试验扭矩水平列表。

ISO 5393:2017 specifies a laboratory performance test method for power assembly tools (referred throughout the document as "tool") for installing threaded fasteners.ISO 5393:2017 provides a method for the measurement of torque repeatability (scatter)- over a range of torque rates as specified in this document,- over a range of torque adjustment as defined by the manufacturer, and- over a number of operating cycles as defined by the manufacturer.ISO 5393:2017 provides a method for the measurement of the precision of the built-in torque measurement system for tools incorporating such a feature. See Annex E.ISO 5393:2017 gives instructions on equipment parameters, what to test for and how to evaluate and present the test data.ISO 5393:2017 is applicable to tools- of any power source, e.g. pneumatic, hydraulic, and electric, including battery-powered,- which apply torque in a generally continuous manner, and- within the torque range 0,5 Nm to 2 000 Nm. Outside this range, it is acceptable to modify the test method providing that the modification is documented in the test report.ISO 5393:2017 is not applicable to- impact or impulse wrenches,- ratchet wrenches or wrenches with ratcheting clutches, and- other tools which advance fasteners in discontinuous increments, overcoming static friction at each increment.ISO 5393:2017 allows a test to be performed at any test torque level; however, in order to minimize the number of test joints necessary for a wide range of test torque levels, a list of preferred test torque levels is provided in Annex A.
