ISO 11148-7:2012规定了用于研磨和切割用于各种材料的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。研磨机可以由压缩空气或液压流体驱动，并且由一个操作者使用并由操作者的手或手支撑，具有或不具有悬架，例如，平衡器 ISO 11148-7:2012适用于与 外围工作速度小于或等于80m/s的研磨产品; 切割轮具有小于或等于100m/s的外围操作速度; 外径公称直径小于或等于230毫米的磨料产品; 外径公称直径小于或等于250mm的切断轮; 丝刷 金刚石和增强[分段]车轮，公称直径小于或等于450毫米; 襟翼盘和襟翼轮。 ISO 11148-7:2012不适用于将其安装在夹具中的磨床的特殊要求和修改。 它不适用于 用ISO 11148-9处理的夹头的研磨机; 抛光机和砂光机用于ISO 11148-8中处理过的涂层磨料的工具，除了挡板和挡板轮] 切割 -

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.
