39、ic, 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 changes. All national differences from the IEC text are included in the CSA Group and UL versions o

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

41、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 organization. If more than one interpretation of the literal

42、 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.
