This is the harmonized CSA Group and UL standard for Hand-Held Motor-Operated Electric Tools — Safety — Part 2-3: Particular Requirements for Grinders, Polishers and Disk-Type Sanders. It is the second edition of CAN/CSA-C22.2 No. 60745-2-3 and the second edition of UL 60745-2-3. This harmonized standard has been jointly revised on November 18, 2022.
