30、60745-1-07 UL 60745-1 v Preface This is the common CSA and UL standard for Hand-Held Motor-Operated Electric Tools Safety Part 1: General Requirements. It is the third edition of CAN/CSA-C22.2 No. 60745-1 and the fourth edition of UL 60745-1. This standard is based on IEC 60745-1, fourth edition. Th
31、is standard (CAN/CSA-C22.2 No. 60745-1, third edition, and UL 60745-1, fourth edition) supersedes CAN/CSA-C22.2 No. 60745-1, second edition, and UL 60745-1, third edition, published in 2004. This common standard was prepared by the Canadian Standards Association (CSA) and Underwriters Laboratories I
32、nc. (UL). 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 Consumer and Com
33、mercial 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 (SCC). This standard has been approved b
34、y the American National Standards Institute (ANSI) as an American National Standard. Where reference is made to a specific number of samples to be tested, the specified number shall be considered a minimum quantity. Note: Although the intended primary application of this standard is stated in its sc
35、ope, 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 and UL.
36、 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 fundament
37、al climatic, geographical, technological, or infrastructural factors, scientific justification, 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 and UL ver
38、sions 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 of an identical or equivalent standard is based on the literal text to determine complian
39、ce with the standard in accordance with the procedural rules of the standards development organization. If more than one literal interpretation has been identified, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reflect the inte
40、nt. CSA effective date The effective date for CSA International will be announced through CSA Informs or a CSA certification notice. UL effective date UL 60745-1 and all revisions to the standard are effective upon publication. vi CAN/CSA-C22.2 No. 60745-1-07 UL 60745-1 JANUARY 13, 2010 A UL effecti
41、ve date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard. General There are five types of National Differences as noted below. The difference type is noted on the first line of the National Difference in the standard. The standard may not include all
42、 types of these National Differences. National Differences from the text of the International Electrotechnical Commission (IEC) publication 60745-1, Hand-Held Motor-Operated Electric Tools Safety Part 1: General Requirements, copyright 2006, are indicated by the following notations: DR These are Nat
43、ional 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 consumers and users of products. D2 These are National Differences from IEC requirements ba
44、sed on existing safety practices. These requirements reflect 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
45、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 contains a description of what the national difference entails. Typically one of the followi
46、ng 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, figure, or annex. Addition is not meant to include adding select words to the base IEC text. Modificati
47、on/Modify A modification 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, figure, or annex of the base IEC text. Deletion/Delete A deletion entails complete deletion of an entire num
48、bered clause, subclause, table, figure, or annex without any replacement text. The text, figures, and tables of International Electrotechnical Commission publication 60745-1, Hand-Held Motor-Operated Electric Tools Safety Part 1: General Requirements, copyright 2006, are used in this standard with t
49、he consent of the International Electrotechnical Commission. The IEC Foreword and Introduction are not a part of the requirements of this standard but are included for information purposes only.
