28、ION WITHOUT PERMISSION FROM UL PREFACE This is the harmonized CSA Group and UL standard for Hand-Held Motor-Operated Electric Tools Safety Part 2-23: Particular Requirements for Die Grinders and Small Rotary Tools. It is the rst edition of CAN/CSA-C22.2 No. 60745-2-23 and the rst edition of UL 60745
29、-2-23. This standard is based on IEC 60745-2-23, rst edition published December 2012. This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Harmonization Working Group for the Adoption of the IEC 60745 Series of Tool Standards are
30、gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. This Standard was reviewed by the CSA Subcommittee on Safety of Hand-Held Motor-Operated Electric Tools under the jurisdiction of the CSA Technical Committee on Co
31、nsumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved as a National Standard of Canada by the Standards Council of Canada. This standard has been ap
32、proved by the American National Standards Institute (ANSI) as an American National Standard. Where reference is made to a specic number of samples to be tested, the specied number is considered a minimum quantity. Note: Although the intended primary application of this standard is stated in its scop
33、e, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of harmonization This standard adopts the IEC text with national differences. This standard is published as an equivalent standard for CSA Group and
34、 UL. An equivalent standard is a standard that is substantially the same in technical content, except as follows: Technical national differences are allowed for codes and governmental regulations as well as those recognized as being in accordance with NAFTA Article 905, for example, because of funda
35、mental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriate. Presentation is word for word except for editorial changes. All national differences from the IEC text are included in the CSA Group and
36、UL versions of the standard. While the technical content is the same in each organizations version, the format and presentation may differ. Reasons for Differences From IEC Differences from the IEC are being added in order to address basic safety requirements present in the USA and Canada. SEPTEMBER

The national difference type is inc
46、luded in the body. There are ve types of National Differences as noted below. The difference type is noted on the rst line of the National Difference in the standard. The standard may not include all types of these National Differences. DR These are National Differences based on the national regulat
47、ory requirements. D1 These are National Differences which are based on basic safety principles and requirements, elimination of which would compromise safety for consumers and users of products. D2 These are national differences from IEC requirements based on existing safety practices. These require
48、ments reect national safety practices, where empirical substantiation (for the IEC or national requirement) is not available or the text has not been included in the IEC standard. DC These are National Differences based on the component standards and will not be deleted until a particular component
49、standard is harmonized with the IEC component standard. DE These are National Differences based on editorial comments or corrections.
