28、 OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the harmonized CSA Group and UL Standard for Motor-Operated Hand-Held Tools, Transportable Tools And Lawn And Garden Machinery Safety Part 3-9: Particular Requirements For Transportable Mitre Saws. It is the First edition of CAN/CSA-C22.2 N
29、o. 62841-3-9 and the First edition of UL 62841-3-9. This harmonized Standard has been jointly revised on April 28, 2017. For this purpose, CSA Group and UL are issuing revision pages dated April 28, 2017. This harmonized standard is based on IEC Publication 62841-3-9: edition 1, Motor-Operated Hand-
30、Held Tools, Transportable Tools And Lawn And Garden Machinery Safety Part 3-9: Particular Requirements For Transportable Mitre Saws issued 8-2014. IEC publication 62841-3-9 is copyrighted by the IEC. This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The effo

While the technical content is the same in each organizations version, the format and presentation may differ. Rea
43、sons 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 standards development organization of an identical or equivalent standard is based on the liter
44、al 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 revision is to be proposed as soon as possible to each of the standards development organizati
45、ons to more accurately reect the intent.
