This part of ISO 11148 specifies safety requirements for hand-held non-electric power tools (hereinafter “assembly power tools for non-threaded mechanical fasteners”) intended for installation, tightening or removal of both breakstem and non-breakstem rivets, bolts, plugs and fasteners from one side of a workpiece into metals, plastics and other materials. The assembly power tools for non-threaded mechanical fasteners can be powered by compressed air, hydraulic fluid or internal combustion engines 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. NOTE 1 At the time of publication, no assembly power tools for non-threaded mechanical fasteners driven by internal combustion engines are known. Once these are identified, it is intended to amend this part of ISO 11148 to include such power tools. This part of ISO 11148 is applicable to: - breakstem fastener, rivet or plug tools; - breakstem lockbolt tools; - mandrel loaded riveting tools; - rivet nut setters. NOTE 2 For examples of assembly power tools for non-threaded mechanical fasteners, see Annex B. 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 assembly power tools for non-threaded mechanical 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 3 EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.
