The Association Française de Normalisation (AFNOR) is preparing a standard on the exposure assessment of vibration from percussive tools. Therefore, a test code was developed for the measurement of vibration from percussive tools under laboratory conditions. The handle vibration from six different breakers, among which three tools were of "antivibration design," was measured with the following energy absorption methods: hydraulic base, steel shot, actual breaking of concrete, AFNOR concrete block, pointed chisel embedded in concrete. The last four methods were applied with breakers held by three successive operators. In addition, the first two were used with tools mounted in a rig which held them vertically and loaded them with a vertical downforce. The results indicated that the steel shot method was preferable although it gave 20% lower vibration results than those recorded for the actual breaking of concrete. It has the advantages of yielding consistent results with low scatter and being simple and cheap. Since difficulties have been experienced during the use of a pneumatic rig with breakers of antivibration design conception, the shot method should be applied with human operators.
法国标准化协会（AFNOR）正在制定一项关于冲击工具振动暴露评估的标准。因此，开发了一种测试规范，用于在实验室条件下测量冲击工具的振动。使用以下能量吸收方法测量了六种不同破碎机的手柄振动，其中三种工具为“抗振设计”：液压底座、钢丸、实际破碎混凝土、AFNOR混凝土块、嵌入混凝土中的尖凿。后四种方法由三名连续操作人员手持破碎机进行应用。此外，前两种方法是将工具安装在一个装置中，该装置将工具垂直固定并施加垂直向下的力。结果表明，钢丸法更可取，尽管其振动结果比实际破碎混凝土时记录的结果低20%。它具有结果一致性好、离散度低、简单且成本低的优点。由于在使用气动装置与抗振设计理念的破碎机时遇到了困难，钢丸法应与人工操作员一起应用。
