2、g April 13, 2000. UL is in the process ofconverting its Standards for Safety to the Standard Generalized Markup Language (SGML), andimplementing an SGML compliant document management and publishing system. SGML - aninternational standard (ISO 8879-1986) - is a descriptive markup language that descri

3、bes a documentsstructure and purpose, rather than its physical appearance on a page. Significant benefits that will resultfrom ULs use of SGML and these new systems include increased productivity, reduced turnaround times,and data and information consistency, reusability, shareability, and portabili

4、ty. However, the fonts,pagination, and general formatting of ULs new electronic publishing system differ from that of ULsprevious publishing system. Consequently, when revision pages are issued for a Standard with the newpublishing system, these differences may result in the printing of pages on whi

5、ch no requirements havebeen changed - these additional pages result from relocation of text due to repagination and reformattingof the Standard with the new publishing system.Announcement Bulletin(s): This Standard contains the announcement bulletin(s) dated October 30, 1997.The announcement bulleti
