标准摘要
[中文适用范围]: ISO 11148 的本部分规定了使用磨料进行磨削和切割用于各种材料的手持式非电动工具(以下简称“磨床”)的安全要求。磨床可由压缩空气或液压油驱动,供一名操作员使用,由操作员的手支撑,可带或不带悬挂装置,例如平衡器。 注 1:截至出版时,尚无已知由内燃机驱动的磨床(ISO 19432 范围内的切割机除外)。一旦确定这些,则旨在修订 ISO 11148 的本部分以包括此类电动工具。 ISO 11148 的本部分适用于与以下设备一起使用的磨床: — 圆周运行速度小于或等于 80 m/s 的磨料产品; — 圆周运行速度小于或等于 100 m/s 的切割轮; — 外径公称直径小于或等于 230 mm 的磨料产品; — 外径小于或等于 250 mm 的切割轮; — 钢丝刷; — 外径小于或等于 450 mm 的金刚石轮和强化轮(分段轮); — 千叶轮和千叶轮。 注 2:磨床示例见附录 B。 注 3:附件 D 列出了与手持磨床一起使用的典型磨料产品。 ISO 11148 的本部分不涉及为将磨床安装在夹具中而对磨床提出的特殊要求和修改。 ISO 11148 的本部分不适用于: — 带夹头的模具磨床,在 ISO 11148-9 中处理; — 抛光机和砂光机(即,与千叶轮和千叶轮以外的涂附磨料一起使用的工具),在 ISO 11148-8 中处理; — 由内燃机驱动并用于切割建筑材料的切割机,在 ISO 19432 中处理; — 轴装钢丝刷,在 ISO 11148-9 中进行了处理。1 ISO 11148 的本部分涉及在按规定使用和制造商可合理预见的误用条件下与砂轮机相关的所有重大危险、危险情况或危险事件,但在潜在爆炸性环境中使用砂轮机的情况除外。注 4 EN 13463-1 给出了潜在爆炸性环境中非电气设备的要求。 [外文原描述]: 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.
