(UL)333 Pfingsten RoadNorthbrook, IL 60062-2096UL Standard for Safety for Systems of Insulating Materials General, UL 1446Sixth Edition, Dated February 8, 2007Revisions: This Standard contains revisions through and including January 30, 2008.SUMMARY OF TOPICSThese revisions to ANSI/UL 1446 include the following changes in requirements: Revision of 8.5.8 to reflect current practice.Revision to the Scope changing the 600 V limit to 1000 VCorrection of Order of the Environmental Conditionings for Insulation System AgingRevision of 5.2.4 - One Temperature Aging of a Magnet WireUL 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 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 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.The following table lists the future effective dates with the corresponding reference:UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM ULThis PDF Standard downloaded from www.bzfxw.comFuture Effective DatesReferencesJuly 28, 2012Paragraphs 5.2.4, 9.2, 10.3, and theReference Publication ANSI/NEMA MW1000 in Clause 2The requirements are substantially in accordance with ULs Proposal(s) on this subject dated July 27,2007 and November 2, 2007.The revisions dated January 30, 2008 include a reprinted title page (page1) for this Standard.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 Standard.The UL Foreword is no longer located within the UL Standard.

In no event shall ULs liability for any damage ever exceed the price paid for this Standard, regardless of the form of the claim.UL will attempt to answer support requests concerning electronic versions of its Standards. However, this support service is offered on a reasonable efforts basis only, and UL may not be able to resolve every support request. UL supports the electronic versions of its Standards only if they are used under the conditions and operating systems for which it is intended. ULs support policies may change from time-to-time without notification.UL reserves the right to change the format, presentation, file types and formats, delivery methods and formats, and the like of both its printed and electronic Standards without prior notice.Purchasers of the electronic versions of ULs Standards for Safety agree to defend, indemnify, and hold UL harmless from and against any loss, expense, liability, damage, claim, or judgement (including reasonable attorneys fees) resulting from any error or deviation introduced while purchaser is storing an electronic Standard on the purchasers computer system.If a single-user version electronic Standard was purchased, one copy of this Standard may be stored on the hard disk of a single personal computer, or on a single LAN file-server or the permanent storage device of a multiple-user computer in such a manner that this Standard may only be accessed by one user at a time and for which there is no possibility of multiple concurrent access.If a multiple-user version electronic Standard was purchased, one copy of the Standard may be stored on a single LAN file-server, or on the permanent storage device of a multiple-user computer, or on an Intranet server. The number of concurrent users shall not exceed the number of users authorized.Electronic Standards are intended for on-line use, such as for viewing the requirements of a Standard, conducting a word search, and the like. Only one copy of the Standard may be printed from each single-user version of an electronic Standard. Only one copy of the Standard may be printed for each authorized user of a multiple-user version of an electronic Standard. Because of differences in the computer/software/printer setup used by UL and those of electronic Standards purchasers, the printed copy obtained by a purchaser may not look exactly like the on-line screen view or the printed Standard.An employee of an organization purchasing a UL Standard can make a copy of the page or pages being viewed for their own fair and/or practical internal use.The requirements in this Standard are now in effect, except for those paragraphs, sections, tables, figures, and/or other elements of the Standard having future effective dates as indicated in the note following the affected item.
