scope:

This part of ISO 11148 applies to hand-held non-electric power tools (hereafter referred to as "grinders") intended for grinding and cutting-off with abrasive products, for use on all kinds of materials. The grinders may be powered by compressed air or hydraulic fluid and 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 date of publication no grinders driven by internal combustion engines are known (other than cutting-off machines within the scope of ISO 19432). When these are identified the standard will be amended to include such power tools. This document covers grinders used with: . abrasive products with a peripheral operating speed less than or equal to 80 m/s; . cutting-off wheels with a peripheral operating speed less than or equal to100 m/s; . abrasive products with outside nominal diameter less than or equal to 230 mm; . cutting-off wheels with outside nominal diameter less than or equal to 250 mm; . wire brushes; . diamond and reinforced [segmented] wheels with outside nominal diameter less than or equal to 450 mm; . flap discs and flap wheels. NOTE 2 For examples of grinders, see annex B. NOTE 3 Typical abrasive products used together with hand-held grinders are listed in annex D. This document does not cover: . special requirements and modifications of grinders for the purpose of mounting them in fixtures. This document does not apply to: . die grinders with collets which are treated in ISO 11148-9; . polishers and sanders [i.e. tools used with coated abrasives except flap discs and flap wheels] which are treated in ISO 11148-8; . cutting-off machines which are driven by internal combustion engines and are used for cutting construction materials, which are treated in ISO 19432; . shaft mounted wire brushes which are treated in ISO 11148-9. This document deals with all significant hazards, hazardous situations or hazardous events with the exception of the use of grinders in potentially explosive atmospheres, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. NOTE 4 EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.
