ISO 11148-6:2012适用于用于拧紧或安装螺纹紧固件的手持式非电动工具（以下简称“螺纹紧固件装配电动工具”）。螺纹紧固件的装配电动工具可由压缩空气、液压油或内燃机驱动，供一名操作员使用，并由操作员的手支撑，带或不带悬架，例如平衡器。 ISO 11148-6:2012涵盖了气动液压脉冲扳手、冲击扳手、紧固件安装工具、螺母扳手、开口扳手（带开口套筒或管螺母扳手的乌鸦脚）、棘轮扳手和螺丝刀。 ISO 11148-6:2012未涵盖螺纹紧固件装配电动工具的特殊要求和修改，以便将其安装在夹具中。 ISO 11148-6:2012规定了按照预期使用工具时，以及在制造商合理预见的误用情况下，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螺纹紧固件装配电动工具除外。

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.
