3、EN ISO 28927-2:2009适用范围：

This part of ISO 28927 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.

This part of ISO 28927 is applicable to hand-held machines (see Clause 5), 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 1/2 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.

ISO 28927的这一部分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、螺母扳手和螺丝刀手柄处的手传振动发射。这是一种型式试验程序，用于确定机器在指定负载下运行时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的这一部分适用于气动或其他方式驱动的手持式机器（见第5条），具有冲击或脉冲作用，关闭式、棘轮式或失速式，以及所有设计——直柄、手枪式握把、角柄或弓柄。它涵盖了具有6.3毫米至40毫米（1/4英寸至1 1/2英寸）公或母驱动输出轴的机器，以及其他几何形状。它不适用于仅用于扭矩反作用臂的螺母扳手。
