4、 revisions through and including December 21, 2006.Summary of TopicsThese revisions add bullet resisting requirements to resist .50 Caliber and 7.62 mm ArmorPiercing Rounds.UL Standards for Safety are developed and maintained in the Standard Generalized Markup Language(SGML). SGML - an international
5、 standard (ISO 8879-1986) - is a descriptive markup language thatdescribes a documents structure and purpose, rather than its physical appearance on a page. Due toformatting differences resulting from the use of ULs new electronic publishing system, please note thatadditional pages (on which no requ
6、irements have been changed) may be included in revision pages dueto relocation of existing text and reformatting of the Standard.The revisions dated December 21, 2006 include a reprinted title page (page1) for this Standard.As indicated on the title page (page 1), this UL Standard for Safety is an A
