An equivalent 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
41、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 protection that the country considers appropriate. Presentation is word for word except for editorial
42、 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 presentation may differ. Reasons for Differences From IEC Differences from the IEC are being added
43、 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 literal text to determine compliance with the standard in accordance with the proced
44、ural 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 organizations to more accurately reect the intent.
