35、-2 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Level of Harmonization This standard adopts the IEC text with national differences. This standard is published as an identical standard for CSA Group and UL. An identical standard is a stan

36、dard that is exactly the same in technical content except for national differences resulting from conicts in codes and governmental regulations and basic safety principles and requirements. Presentation is word for word except for editorial changes. All national differences from the IEC text are inc

37、luded in the CSA Group and UL versions of the standard. While the technical content 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 situatio

38、ns present in the US and Canada. Interpretations 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 organizatio

39、n. 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 organizations to more accurately reect the intent.

44、In the CSA Group and UL publications of this standard, National Differences from the text of International Electrotechnical Commission (IEC) Publication 61058-1-2, Switches for Appliances Part 1-2: Requirements for Electronic Switches, copyright 2016, are indicated by notations (differences) and are

45、 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. The standard may not include all types of these National Differences. DR

46、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 consumers and users of products. D2 These are National Differences from IEC re

47、quirements 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 IEC standard. DC These are National Differences based on the component sta

48、ndards 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 contains a description of what the national difference entails. Typically one of

49、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 annex. 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
