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. SGML -
an international standard (ISO 8879-1986) - is a descriptive markup language that describes a document’s
structure and purpose, rather than its physical appearance on a page. Significant benefits that will result
from UL’s use of SGML and these new systems include increased productivity, reduced turnaround times,
and data and information consistency, reusability, shareability, and portability. However, the fonts,
pagination, and general formatting of UL’s new electronic publishing system differ from that of UL’s
previous publishing system. Consequently, when revision pages are issued for 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 changed 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
