29、rmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the International Harmonization Committee (IHC) for the adoption of the IEC series of standards for Hand-Held, Motor-Operated, and Transportable Tools and Lawn and Garden Machinery UL 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 C

31、onsumer 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 (SCC). This standard has

32、been approved by the American National Standards Institute (ANSI) as an American National Standard. Application of Standard Where reference is made to a specic number of samples to be tested, the specied number is to be considered a minimum quantity. Note: Although the intended primary application o

33、f 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. This CAN/CSA-C22.2 No. 62841-3-1, Standard for Electric Motor-Operated Hand-Held Tools, Transportable Tools And Lawn

34、And Garden Machinery Safety Part 3-1: Particular Requirements For Transportable Table Saws is to be used in conjunction with the First edition of CAN/CSA-C22.2 No. 62841-1. The requirements for transportable table saws are contained in this Part 3 Standard and CAN/CSA-C22.2 No. 62841-1. Requirements

This standard is published as an equivalent standard for CSA Group and UL. An equivalent standard is a standard that is substa

39、ntially 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 fundamental climatic, geographical, technological, or infrast

40、ructural 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 UL versions of the standard. While the technical content

41、 is the same in each organizations version, the format and presentation may differ. Reasons for Differences From IEC National Differences from the IEC are being added in order to address safety and regulatory situations present in the US and Canada. Interpretations The interpretation by the standard

42、s development organization 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 interpretation of the literal text has been identied, a revisio

43、n is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent.
