2、Edition, Dated April 26, 1995Revisions: This Standard contains revisions through and including January 31, 2001.UL is in the process of converting its Standards for Safety to the Standard Generalized Markup Language (SGML), and implementing an SGML compliant document management and publishing system
3、. SGML - an international standard (ISO 8879-1986) - is a descriptive markup language that describes a documents structure and purpose, rather than its physical appearance on a page. Significant benefits that will result from ULs use of SGML and these new systems include increased productivity, redu
4、ced turnaround times, and data and information consistency, reusability, shareability, and portability. However, the fonts, pagination, and general formatting of ULs new electronic publishing system differ from that of ULs previous publishing system. Consequently, when revision pages are issued for
5、a Standard with the new publishing system, these differences may result in the printing of pages on which no requirements have been changed - these additional pages result from relocation of text due to repagination and reformatting of the Standard with the new publishing system.Text that has been c
6、hanged in any manner is marked with a vertical line in the margin. Changes in requirements are marked with a vertical line in the margin and are followed by an effective date note indicating the date of publication or the date on which the changed requirement becomes effective.The revised requiremen
7、ts are substantially in accordance with ULs Bulletin(s) on this subject dated July7, 2000. The bulletin(s) is now obsolete and may be discarded.The revisions dated January 31, 2001 include a reprinted title page (page1) for this Standard.As indicated on the title page (page 1), this UL Standard for
