CAN/CSA-C22.2 No.745-1-95 (R1999)

1. Scope 1.1 This standard applies to portable electric motor-operated or magnetically-driven tools, intended for indoor or outdoor use, in non-hazardous locations, in accordance with the Canadian Electrical Code, Part I and the National Electrical Code (NFPA 70). It applies to tools rated not more than 440 V (not more than 250 V for tools employing a universal motor). Tools with an electric heating element incorporated are within the scope of this standard. Special requirements for battery-powered tools are defined in UL 745-3 and C22.2 No. 745-3. For tools intended to be used on board ships or aircraft, additional requirements may be necessary, and in hazardous locations, for example, where explosions are liable to occur, special constructions may be required. For tools intended to be used in tropical countries, special requirements may be necessary. This standard applies to accessories and mechanical attachments for use with portable electric tools. These requirements are outlined in Appendix F. This standard applies to attachments that contain electrical and electronic components. In this case, the attachment shall be evaluated with the tool and a determination must be made as to which clauses apply. This standard applies to, but the scope is not limited to: hand tools, such as drills, screwdrivers, nut runners, tappers, hammers, impact wrenches, saws, sanders, polishers, buffers, shears, nibblers, grinders, staplers, valve seat grinders and lappers, cylinder borers, and concrete vibrators; transportable tools, such as diamond core drills, drain cleaners, magnetic drill presses, pipe threaders, and pipe benders. This standard does not apply to fixed or stationary electric tools, gardening appliances, garage equipment, soldering irons or guns, painting equipment, floor-finishing machines, heat guns, or other equipment covered by individual requirements. Covered within this standard are Class I, II, and III tools. 1.2 This standard is concerned with safety and takes into account the influence on safety of components necessary to achieve a degree of radio and television interference suppression.
