ÖNORM EN 792-7

This European Standard applies to hand-held non-electric power tools driven by rotary or linear motors, powered by compressed air or hydraulic fluid and intended to be used by one operator and supported by: - the operators hand or hands; - a harness; - a suspension, e. g. a balancer. This European Standard applies to hand-held non-electric power tools intended for grinding and cutting-off, with bonded, coated and super abrasive products for use on all kinds of materials. This European Standard lists the significant hazards caused by such power tools and specifies safety requirements valid for different aspects of safety during their foreseeable lifetime. This part of the standard covers power tools 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 300 mm; - wire brushes. This Part of the standard does not apply to: - die grinders with collets which are treated in EN 792-9; - polishers and sanders which are treated in EN 792-8; - cutting-off machines used for construction, rescue purposes which are driven by an internal combustion engine which are treated in EN 1454. There are no grinders covered by this Part of this European Standard driven by internal combustion engines. Typical abrasive products used together with hand-held grinders are listed in annex C. Special requirements and modifications on a hand-held power tool for the purpose of mounting it in a fixture are not covered by this part. NOTE At the date of publication no grinders driven by internal combustion engines are known.
