BS EN ISO 28927-2:2009+A1:2017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的本部分适用于手持式机器（见第5条），该机器由气动或其他方式驱动，具有冲击或脉冲作用，可关闭- 关闭，棘轮或失速型，所有设计-直，手枪把手，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11/2英寸）外螺纹或内螺纹驱动输出轴的机器，以及其他几何形状的机器。它不适用于仅用于扭矩反作用臂的Nutrunner。交叉引用:ISO 5349:2001ISO 2787EN 12096:1997ISO 20643:2005 Ed 1ISO 691:2005（R09）Ed 4ISO 17066:2007 Ed 1（R11）ISO 5391:2003 Ed 2DIN 2093ISO 12100IEC 60745包含以下内容:修订，2017年12月

BS EN ISO 28927-2:2009+A1:2017 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 11/2 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.Cross References:ISO 5349:2001ISO 2787EN 12096:1997ISO 20643:2005 Ed 1ISO 691:2005 (R09) Ed 4ISO 17066:2007 Ed 1 (R11)ISO 5391:2003 Ed 2DIN 2093ISO 12100IEC 60745Incorporates the following:Amendment, December 2017
