This part of ISO 11148 specifies safety requirements for hand-held non-electric power tools (hereinafter fastener driving tools ) intended for installation of a fastener, forming a mechanical connection or attachment with the workpiece which are for example wood and wood-based materials, plastic materials, fibre materials loose or compacted, cementitious materials, metals and combinations of these materials. The fastener driving tools for fasteners can be powered by compressed air or combustible gases (which may be ignited by a battery or accumulator) and the energy is transmitted to an impacted element by an intermediary component that does not leave the device. These tools 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. This part of ISO 11148 is applicable to fastener driving tools in which energy is applied to a loaded fastener for the purpose of driving this into a workpiece. This part of ISO 11148 is not applicable to fastener driving tools in which the energy for driving fasteners is drawn from powder-actuated cartridges, hydraulics or from any type of electrical supply. This part of ISO 11148 is not applicable to special requirements and modifications of hand-held power tools for the purpose of mounting them in a fixture. This part of ISO 11148 deals with all significant hazards, hazardous situations or hazardous events relevant to fastener driving tools for fasteners when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, with the exception of the use of power tools in potentially explosive atmospheres. NOTE EN 13463-1 gives requirements for non- electrical equipment for potentially explosive atmospheres.
