4、gsten Road Northbrook, IL 60062-2096 UL Standard for Safety for Solvent Distillation Units, UL 2208 Second Edition, Dated February 11, 2005 Revisions: This Standard contains revisions through and including December 19, 2006 Summary of Topics The standard is being revised to update references in para
5、graphs 1.6 and 4.3.4. 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 markup language that describes a documents structure and purpose, rather than its physical appearance on
6、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 included in revision pages due to relocation of existing text and reformatting of the Standard. Text that has be
7、en 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. The following tab
8、le lists the future effective dates with the corresponding item. Future Effective DateReferences December 19, 2008Paragraph 4.3.4 The revisions dated December 19, 2006 include a reprinted title page (page1) for this Standard. The revised requirements are substantially in accordance with ULs Proposal
9、(s) on this subject dated October 20, 2006. As indicated on the title page (page 1), this UL Standard for Safety is an American National Standard. Attention is directed to the note on the title page of this Standard outlining the procedures to be followed to retain the approved text of this ANSI/UL
10、Standard. The UL Foreword is no longer located within the UL Standard.
