2、 Edition, Dated September 30, 1997Revisions: This Standard contains revisions through and including August 19, 1998. UL is in the process ofconverting its Standards for Safety to the Standard Generalized Markup Language (SGML). SGML - aninternational standard (ISO 8879-1986) - is a descriptive marku
