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 t
40、echnical 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 infrastructural factors, sci
41、entic 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 is the same in each
42、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 The interpretation by the standards development organization of
43、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 revision is to be proposed as soon as
44、 possible to each of the standards development organizations to more accurately reect the intent.
