This part of ISO 11148 specifies safety requirements for hand-held non-electric power tools (hereinafter “rotary percussive drills”) intended for making holes in hard materials, such as rock and concrete. The rotary percussive drills can be powered by compressed air, hydraulic fluid or internal combustion engines (ICEs) 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. This part of ISO 11148 is applicable to: - plug hole drills; - rock drills; - rotary hammers. NOTE 1 For examples of rotary percussive drills, see Annex B. This part of ISO 11148 is not applicable to special requirements and modifications of rotary percussive drills 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 rotary percussive drills 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 rotary percussive drills in potentially explosive atmospheres. NOTE 2 EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.
