28、ON FROM UL Preface This is the harmonized CSA and UL standard for hand-held motor-operated electric tools; drills and impact drills. It is the second edition of CAN/CSA-C22.2 No. 60745-2-1 and the second edition of UL 60745-2-1. This standard is based on IEC 60745-2-1, second edition. This harmonize

29、d standard has been jointly revised on October 6, 2010. For this purpose, CSA and UL are issuing revision pages dated October 6, 2010. This harmonized standard was prepared by the Canadian Standards Association (CSA) and Underwriters Laboratories Inc. (UL). This standard was reviewed by the CSA Subc

30、ommittee on Portable Electric Tools, under the jurisdiction of the CSA Technical Committee on Consumer 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 approve

31、d as a National Standard of Canada by the Standards Council of Canada. This standard has been approved 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

32、quantity. Note: Although the intended primary application of this standard is stated in its scope, 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 w

33、ith national differences. This standard is published as an equivalent standard for CSA and 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 tho

34、se recognized as being in accordance with NAFTA Article 905, for example because of fundamental 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 editori

35、al changes. All national differences from the IEC text are included in the CSA and UL versions of the standard. While the technical content is the same in each organizations version, the format and presentation may differ. Interpretations The interpretation by the standards development organization

36、of an identical or equivalent standard is based on the literal text to determine compliance with the standard in accordance with the procedural rules of the standards development organization. If more than one literal interpretation has been identied, a revision is to be proposed as soon as possible

37、 to each of the standards development organizations to more accurately reect the intent.

41、IONAL DIFFERENCES In the CSA and UL publications of this standard, National Differences from the text of International Electrotechnical Commission (IEC) Publication 60745-2-1, Safety Requirements for Hand-Held Motor-Operated Electric Tools Safety Part 2-1: Particular Requirements for Drills and Impa

42、ct Drills, copyright 2008, are indicated by notations (differences) and are presented in bold text. The national difference type is included 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

43、. The standard may not include all types of these National Differences. DR These are National Differences based on the national regulatory requirements. D1 These are National Differences which are based on basic safety principles and requirements, elimination of which would compromise safety for con

44、sumers and users of products. D2 These are national differences from IEC requirements based on existing safety practices. These requirements 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

45、 IEC standard. DC These are National Differences based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard. DE These are National Differences based on editorial comments or corrections. Each national difference contai

46、ns a description of what the national difference entails. Typically one of the following words is used to explain how the text of the national difference is to be applied to the base IEC text: Addition / Add - An addition entails adding a complete new numbered clause, subclause, table, gure, or anne

47、x. Addition is not meant to include adding select words to the base IEC text. Modication / Modify - A modication is an altering of the existing base IEC text such as the addition, replacement or deletion of certain words or the replacement of an entire clause, subclause, table, gure, or annex of the

48、 base IEC text. Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause, table, gure, or annex without any replacement text.
