28、ort 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 gratefully acknowledged. This standard is considered suitable for use for conformity assessment within th
29、e 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 Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical S
30、afety, 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 by the American National Standards Institute (ANSI) as an American National Standard. Appli

Level of harmonization This standard adopts the IEC text with editorial national differences. This standard is published as an equivalent standard for CSA Group and UL. An equiv
38、alent 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 fundamental climat
39、ic, 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 UL versions o
40、f 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 safety and regulatory situations present in the US and Canada. Interpretations
41、The interpretation by the standards 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
42、 text has been identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent.
