The Machinery Directive 89/392/EEC contains the obligation to inform the user about the hand-arm vibration emission of hand-held and hand-guided tools and of steering wheals etc. at mobile equipment of the weighted acceleration value exceeds 2.6 m/s2. The measurements should be made under standardized working conditions (type testing) to obtain comparable results and to allow the user the selection of tools with the lowest vibration emission. The European Standardization Organization CEN is obliged to elaborate all necessary standards for type testing, which only unity realistic working conditions and exclude evaluation of health risks arising from the use of these tools. This approach is quite new and requires a great effort from the experts of the involved manufactures and the responsible occupational safety authorities. The presentation informs about the present stage of this work in the CEN Technical Committee 231 "Mechanical Vibration and Shock" which is responsible for the elaboration of the general measurement standards as a basis for the specific test codes from the machine groups oriented Technical Committees.
《欧盟机器指令89/392/EEC》规定，当手持式和手扶式工具以及移动设备上的方向盘等的加权加速度值超过2.6米每二次方秒时，有义务向用户告知其手臂振动排放情况。测量应在标准化工作条件下（型式试验）进行，以获得可比结果，并便于用户选择振动排放最低的工具。欧洲标准化组织CEN有义务制定所有必要的型式试验标准，这些标准仅统一实际工作条件，不包括对使用这些工具所产生健康风险的评估。这种方法相当新颖，需要相关制造商的专家和负责的职业安全当局付出巨大努力。本报告介绍了CEN技术委员会231“机械振动与冲击”中这项工作的现阶段情况，该委员会负责制定通用测量标准，作为面向机器组的技术委员会特定测试规范的基础。
