ISO 28927-2:2009规定了一种实验室方法，用于测量用于拧紧和松开螺纹紧固件的手持式电动扳手、Nutronner和螺丝刀手柄处的手传振动发射。这是一种型式试验程序，用于确定在规定负载下运行时机器夹紧区域的振动幅度。该方法仅针对紧固任务进行了测试。其目的是将结果用于比较同一类型机器的不同型号。 ISO 28927-2:2009适用于手持式机器，通过气动或其他方式驱动，具有冲击或脉冲作用- 关闭，棘轮或失速型，所有设计-直，手枪握把，角度或弓形手柄。它包括带有6.3毫米至40毫米（1/4英寸至1英寸）外螺纹或内螺纹驱动输出轴的机器，以及其他几何形状。它不适用于仅用于扭矩反作用臂的Nutrunner。

ISO 28927-2:2009 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power-driven wrenches, nutrunners and screwdrivers used for tightening and loosening threaded fasteners. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine when operating at a specified load. The method has been tested for fastening tasks only. It is intended that the results be used to compare different models of the same type of machine. ISO 28927-2:2009 is applicable to hand-held machines, driven pneumatically or by other means, with impact or impulse action, of shut-off, ratchet or stall type, and of all designs — straight, pistol？grip, angle or bow handle. It covers machines with 6,3 mm to 40 mm (1/4 in to 1？ in) male or female drive output shafts, as well as other geometries. It is not applicable to nutrunners designed to be used only in torque reaction arms.
