6、ndards 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 di
7、fferences 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
8、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 revisions dated January 26, 2006 include
9、a reprinted title page (page1) for this Standard. The revisions dated January 26, 2006 editorially replace all references to UL 1020 with the reference to UL 60691.

10、tained 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 and the compliance of a product with respect to the requirements for that p

However, this support service is offered on a reasonable efforts basis only, and UL may not be able to resolve
18、 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.

19、i le types and formats, delivery methods and formats, and the like of both its printed and electronic Standards without prior notice.

20、ge, 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.

21、he 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 which there is no possibility of multiple concurrent access.
