PrefaceThis is the harmonized CSA Group and UL Standard for Electric Motor-Operated Hand-Held Tools, Transportable Tools and Lawn and Garden Machinery - Safety - Part 2-3: Particular Requirements for Hand-Held Grinders, Disc-Type Polishers and Disc-Type Sanders. It is the First edition of CSA C22.2 No. 62841-2-3:21 and the First edition of UL 62841-2-3. This harmonized standard is based on IEC Publication 62841-2-3: First edition, Electric Motor-Operated Hand-Held Tools, Transportable Tools and Lawn and Garden Machinery - Safety - Part 2-3: Particular Requirements for Hand-Held Grinders, Disc-Type Polishers and Disc-Type Sanders, issued April 2020. IEC publication 62841-2-3 is copyrighted by the IEC. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.ScopeThis clause of Part 1 is applicable, except as follows: Addition: This part of IEC 62841 applies to hand-held GRINDERS, DISC-TYPE POLISHERS and DISC-TYPE SANDERS, including angle, straight and vertical tools, intended for use on various materials except magnesium, with a RATED CAPACITY not exceeding 230 mm. For GRINDERS, the RATED NO-LOAD SPEED does not exceed a peripheral speed of the ACCESSORY of 80 m/s at RATED CAPACITY. This standard does not apply to dedicated cut-off machines.NOTE 101 It is planned that a document on cut-off machines will be published. This standard does not apply to orbital polishers and orbital sanders.NOTE 102 It is planned that a document on orbital polishers and orbital sanders will be published. This standard does not apply to die grinders.NOTE 103 Die grinders are covered by IEC 62841-2-23.
