37、ERMISSION FROM UL 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 equivalent standard is a standard that is substantially the same in technical content, except as follows: Tech

38、nical 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 infrastructural factors, scientic justication, or the level of protec

39、tion 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 is the same in each organizations version, the format and pre

40、sentation 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 standards development organization of an identical or equivalent stand

41、ard 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 revision is to be proposed as soon as possible to each of the standar
