ISO 11148-7:20 12规定了用于研磨和切割研磨产品的手持式非电动工具（以下简称“研磨机”）的安全要求，用于所有类型的材料。研磨机可以由压缩空气或液压流体提供动力，并且旨在由一个操作者使用并由操作者的一只或多只手支撑，具有或不具有悬架，例如平衡器。 ISO 11148-7:20 12适用于与以下设备一起使用的研磨机: 周边运行速度小于或等于80m/s的磨料产品； 周边运行速度小于或等于100米/秒的切割轮； 外公称直径小于或等于230毫米的磨料产品； 外公称直径小于或等于250毫米的切割轮； 钢丝刷；外公称直径小于或等于450毫米的金刚石和强化[分段]砂轮； 瓣盘和瓣轮。 ISO 11148-7:20 12不涵盖为将磨床安装在夹具中而对磨床进行的特殊要求和修改。 它不适用于 带夹头的模具磨床，经ISO 11148-9处理； 经ISO 11148-8处理的抛光机和砂光机【即除瓣盘和瓣轮之外的涂附磨料使用的工具】； 由内燃机驱动并用于切割建筑材料的切割机，其在ISO 19432中被处理； 经ISO 11148-9处理的轴装钢丝刷。

ISO 11148-7:2012 specifies safety requirements for hand-held non-electric power tools (hereinafter "grinders") intended for grinding and cutting-off with abrasive products, for use on all kinds of materials. The grinders can be powered by compressed air or hydraulic fluid and are intended to be used by one operator and supported by the operator's hand or hands, with or without a suspension, e.g. a balancer. ISO 11148-7:2012 is applicable togrinders used with:

• abrasive products with a peripheral operating speed less than or equal to 80 m/s;
• cutting-off wheels with a peripheral operating speed less than or equal to100 m/s;
• abrasive products with an outside nominal diameter less than or equal to 230 mm;
• cutting-off wheels with an outside nominal diameter less than or equal to 250 mm;
• wire brushes;
• diamond and reinforced [segmented] wheels with an outside nominal diameter less than or equal to 450 mm;
• flap discs and flap wheels.

ISO 11148-7:2012 does not cover special requirements and modifications of grinders for the purpose of mounting them in fixtures. It is not applicable to

• die grinders with collets which are treated in ISO 11148-9;
• polishers and sanders [i.e. tools used with coated abrasives except flap discs and flap wheels] which are treated in ISO 11148-8;
• cutting-off machines which are driven by internal combustion engines and are used for cutting construction materials, which are treated in ISO 19432;
• shaft mounted wire brushes which are treated in ISO 11148-9.
