4、Road Northbrook, IL 60062-2096 UL Standard for Safety for Insulating Bushings, UL 635 Second Edition, Dated October 31, 2001 Revisions: This Standard contains revisions through and including August 14, 2007. Summary of Topics These revisions are being issued to transfer requirements for instructions

5、 for installing bushings from Paragraph 15.3 to a new Paragraph 15.3.1. 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 markup language that describes a documents structure an

6、d 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

7、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 change

8、d requirement becomes effective. The revised requirements are substantially in accordance with ULs Proposal(s) on this subject dated June 1, 2007. The revisions dated August 14, 2007 include a reprinted title page (page1) for this Standard. The UL Foreword is no longer located within the UL Standard

9、. For information concerning the use and application of the requirements contained in this Standard, the current version of the UL Foreword is located on ULStandardsInfoNet at: http:/ The master for this Standard at ULs Northbrook Office is the official document insofar as it relates to a UL service

10、 and the compliance of a product with respect to the requirements for that product and service, or if there are questions regarding the accuracy of this Standard. ULs Standards for Safety are copyrighted by UL. Neither a printed copy of a Standard, nor the distribution diskette for a Standard-on-Dis

11、kette and the fi le for the Standard on the distribution diskette should be altered in any way.

13、 most recently adopted revisions.

15、In no event will UL be liable for any special, incidental, consequential, indirect or similar damages, including loss of profi ts, lost savings, loss of data, or any other damages arising out of the use of or the inability to use this Standard, even if UL or an authorized UL representative has been

16、advised of the possibility of such damage. 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 of

17、fered 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

18、 notifi cation. UL reserves the right to change the format, presentation, fi le 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, indemnif

19、y, 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 elec

20、tronic 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 fi le-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 wh

21、ich 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 fi le-server, or on the permanent storage device of a multiple-user computer, or on an Intranet server. The number of concur

22、rent 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 Stand

23、ard. 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 loo

24、k 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

25、, sections, tables, fi gures, and/or other elements of the Standard having future effective dates as indicated in the note following the affected item. The prior text for requirements that have been revised and that have a future effective date are located after the Standard, and are preceded by a S

26、UPERSEDED REQUIREMENTS notice.
