3、 Northbrook, IL 60062-2096 UL Standard for Safety for Fabricated Scaffold Planks and Stages, UL 1322 Fifth Edition, Dated June 24, 1998 Revisions: This Standard contains revisions through and including December 15, 2004. Summary of Topics These revisions are being issued to indicate the deletion of
4、1.3 from the Scope and correction to the maximum length and width dimensions for two-person fabricated platforms in Table 4.1. UL Standards for Safety are developed and maintained in the Standard Generalized Markup Language (SGML). SGML - an international standard (ISO 8879-1986) - is a descriptive
5、markup language that describes a documents structure and purpose, rather than its physical appearance on a page. Due to formatting differences resulting from the use of ULs new electronic publishing system, please note that additional pages (on which no requirements have been changed) may be include
6、d in revision pages due to relocation of existing text and reformatting of the Standard. 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
7、the date of publication or the date on which the changed requirement becomes effective. The following table lists the future effective dates with the corresponding item.
