ISO 11148-6:2012适用于用于紧固或安装螺纹紧固件的手持式非电动工具（以下简称“螺纹紧固件组装电动工具”）。用于螺纹紧固件的组合电动工具可以由压缩空气，液压流体或内燃机驱动，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 11148-6:2012涵盖气动冲击扳手，冲击扳手，紧固件安装工具，螺母，开口扳手（带开口插座或管螺母扳手的乌鸦），棘轮扳手和螺丝刀。 ISO 11148-6:2012不涵盖用于将其安装在固定装置中的螺纹紧固件组装电动工具的特殊要求和修改。 ISO 11148-6:2012涉及所有重大危险，危险情况或危险事件，当工具按预期使用和在制造商可合理预见的误用条件下使用时，除了使用螺纹紧固件的组装电动工具在潜在的爆炸性环境中

ISO 11148-6:2012 applies to hand-held non-electric power tools (hereinafter "assembly power tools for threaded fasteners") intended for tightening or installing of threaded fasteners. The assembly power tools for threaded fasteners can be powered by compressed air, hydraulic fluid or internal combustion engines and are intended for use by one operator and supported by the operator's hand or hands, with or without a suspension, e.g. a balancer. ISO 11148-6:2012 covers air-hydraulic impulse wrenches, impact wrenches, fastener installation tools, nutrunners, open-ended spanners (crow-foot with open-ended socket or tube nut wrench), ratchet wrenches and screwdrivers. ISO 11148-6:2012 does not cover special requirements and modifications of assembly power tools for threaded fasteners for the purpose of mounting them in fixtures. ISO 11148-6:2012 deals with all significant hazards, hazardous situations or hazardous events when the tools are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, with the exception of the use of assembly power tools for threaded fasteners in potentially explosive atmospheres.
