标准摘要
[中文适用范围]: ISO 28927 的本部分规定了一种测量直磨机手柄处手动传递振动发射的实验室方法。它是一种型式试验程序,用于确定装有指定测试轮并在空载条件下运行的机器抓握区域的振动幅度。ISO 28927 的本部分适用于手持式机器(见第 5 条),由气动或其他方式驱动,用于磨削和表面精加工,使用 1 型直磨轮、4 型锥形轮和圆柱塞,例如 16 型(圆柱塞,锥形锥体)、18 型(圆柱塞,平端)、18R 型(圆柱塞,圆端)和 19 型(圆柱塞,锥形辊形),用于各种材料。它不适用于使用钢丝刷的磨床,也不适用于插入工具安装在夹头中的模具磨床。注 1:图 1 至图 3 显示了 ISO 28927 本部分涵盖的典型机器。结果旨在用于比较同一类型机器的不同型号。注 2:为避免与术语“电动工具”和“插入式工具”混淆,下文将前者称为“机器”。 [外文原描述]: ISO 28927-4:2010 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of straight grinders. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with a specified test wheel and run under no-load conditions. ISO 28927-4:2010 is applicable to hand-held machines, driven pneumatically or by other means, intended for grinding and surface finishing using straight grinding wheels type 1, tapered wheels type 4 and cylindrical plugs, e.g. of type 16 (cylindrical plug, tapered cone), 18 (cylindrical plug, flat end), 18R (cylindrical plug, rounded end) and 19 (cylindrical plug, taper-roll shaped), for use on all kinds of materials. It is not applicable to grinders used with wire brushes, nor is it applicable to die grinders where the inserted tool is mounted in a collet.
