The correct e
4、ffective date is August 16, 2005. As noted in the Commitment for Amendments statement located on the back side of the title page, UL and CSA are committed to updating this binational standard jointly. Since the revisions are limited to the Preface, title page, and transmittal pages, only UL is forma
5、lly revising its standard. UL Standards for Safety are developed and maintained in the Standard Generalized Markup Language (SGML). SGML - an international standard (ISO 8879-1986) - is a descriptive markup language that describes a documents structure and purpose, rather than its physical appearanc
6、e on a page. Due to formatting differences resulting from the use of ULs new electronic publishing system, please note that additional pages (on which no requirements have been changed) may be included in revision pages due to relocation of existing text and reformatting of the Standard. The followi
7、ng table lists the future effective dates with the corresponding item. Future Effective DateReferences August 16, 2005Entire Standard The revisions are substantially in accordance with ULs Bulletin(s) on this subject dated December 15, 2004.
