Arc-Fault Circuit-Interrupters(doc41)简介开始 Underwriters Laboratories Inc. (UL) 333 Pfingsten Road Northbrook, IL 60062-2096 UL Standard for Safety for Arc-Fault Circuit-Interrupters, UL 1699 First Edition, Dated February 26, 1999 Revisions: This Standard contains revisions through and including May 15, 2003. SUMMARY OF TOPICS: This revision of UL 1699 is being issued to add Test Method to requirements for Surge Testing, clarify requirements for Installation Instructions, include miscellaneous requirements, and revise requirements for Peak Inrush Current. 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 document’s structure and purpose, rather than its physical appearance on a page. Due to formatting differences resulting from the use of UL’s 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 item. Arc-Fault Circuit-Interrupters(doc41)简介结束,下载后阅读全部内容 |
