ISO 20643:2005为手持式和手持式动力驱动机械的振动测试规范的起草提供了依据。它规定了在型式试验期间，根据频率加权均方根（r.m.s.）加速度测定手传振动发射。对于不存在振动测试代码的机器，它也可用于确定排放值，并包含设计适当测试的充分指南。适用于手持式电动工具（如削片锤、砂光机）、手动导向动力机器（如割草机、单轴割草机）- 车轴拖拉机、振动压路机）和其他类型的动力机器，配有手柄、导梁或类似的控制装置，所有动力源（电动、液压、气动、内燃机等）。它不适用于振动通过工件传递到用户手上的固定机械，也不适用于操作员位置在机器上的移动机械的方向盘或操纵杆传递的振动。

ISO 20643:2005 provides the basis for the drafting of vibration test codes for hand-held and hand-guided power-driven machinery. It specifies the determination of hand-transmitted vibration emission in terms of frequency-weighted root-mean-square (r.m.s.) acceleration during type testing. For machines where vibration test codes do not exist, it can also be used for determination of emission values and contains sufficient guidance for designing an appropriate test. It is applicable to hand-held power tools (e.g. chipping hammers, sanders), hand-guided powered machines (e.g. lawn mowers, single-axle tractors, vibratory rollers), and other types of powered machines fitted with handles, guiding beams or similar means of control, of all power sources (electrical, hydraulic, pneumatic, internal combustion engine, etc.). It is not applicable to fixed machinery in which the vibration is transmitted to the hands of the user through the workpiece, nor to vibration transmitted from steering wheels or control levers of mobile machinery where the operator's position is on the machine.
