手持便携式电动工具.振动辐射的评价用试验方法.第10部分:冲击钻,冲击锤和冲击压碎机

[中文适用范围]： ISO 28927 的本部分规定了一种实验室方法，用于测量带有和不带有旋转动作的手持电动冲击机器（便携式凿岩机、塞孔钻、旋转锤、破碎机（例如路面破碎机、混凝土破碎机或道路破碎机）、铆钉锤、凿锤、镐或类似设备）手柄处的手传振动发射。这是一种型式试验程序，用于确定装有插入式工具头的机器抓握区域的振动幅度。ISO 28927 的本部分适用于手持机器（见第 5 条），由气动或其他方式驱动，用于在岩石和混凝土等硬质材料上钻孔。它也适用于用于向下工作以破碎硬质材料（混凝土、岩石、路面、沥青等）的破碎机，以及用于在任何方向工作以进行铆接或凿凿工作的锤子。它不适用于带有直接机械冲击机构的冲击钻。 ISO 28927 的本部分不适用于手动引导的千斤顶腿式凿岩机和推料凿岩机（进给力不是用手施加的，而是由附加装置施加的）。结果旨在用于比较同一类型机器的不同型号。注：为避免与“电动工具”和“插入工具”混淆，下文将前者称为“机器”。 [外文原描述]： ISO 28927-10:2011 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power driven percussive machines with and without rotary action [portable rock drills, plug hole drills, rotary hammers, breakers (e.g. pavement breakers, concrete breakers or road breakers), riveting hammers, chipping hammers, pick hammers or similar]. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with an inserted tool bit. ISO 28927-10:2011 is applicable to hand-held machines, driven pneumatically or by other means, intended for making holes in hard materials, such as rock and concrete. It is also applicable to breakers intended to work downwards to break hard materials (concrete, rock, pavement, asphalt, etc.) and for hammers intended to work in any direction to perform riveting or chiselling work. It is not applicable to impact drills with direct mechanical impact mechanisms. ISO 28927-10:2011 is not applicable to jack leg type rock drills and push feed rock drills, which are hand guided (the feed force is not applied by hand, but by an additional device).
