UL shall not incur any obligationor liability for damages, including consequential damages, arising out of or in connection with the use, interpretation,or reliance upon a UL Standard.UL 1684 is adopted, with permission, from Underwriters Laboratories Inc. and is Copyrighted by UnderwritersLaboratories Inc.Revisions of UL Standards for Safety are issued from time to time. A UL Standard for Safety is current only if itincorporates the most recently adopted revisions.

(UL)333 Pfingsten RoadNorthbrook, IL 60062-2096UL Standard for Safety for Reinforced Thermosetting Resin Conduit (RTRC) and Fittings, UL 1684Third Edition, Dated March 17, 2000UL is in the process of converting its Standards for Safety to the Standard Generalized Markup Language(SGML), and implementing an SGML compliant document management and publishing system. SGML an international standard (ISO 8879-1986) - is a descriptive markup language that describes a document’sstructure and purpose, rather than its physical appearance on a page. Significant benefits that will resultfrom UL’s use of SGML and these new systems include increased productivity, reduced turnaround times,and data and information consistency, reusability, shareability, and portability. However, the fonts,pagination, and general formatting of UL’s new electronic publishing system differ from that of UL’sprevious publishing system. Consequently, when revision pages are issued for a Standard with the newpublishing system, these differences may result in the printing of pages on which no requirements havebeen changed - these additional pages result from relocation of text due to repagination and reformattingof the Standard with the new publishing system.Announcement Bulletin(s): This Standard contains the announcement bulletin(s) dated April 4, 1996. Theannouncement bulletin is located at the end of the Standard.The master for this Standard at UL’s Northbrook Office is the official document insofar as it relates to aUL service 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.UL’s Standards for Safety are copyrighted by UL. Neither a printed copy of a Standard, nor the distributiondiskette for a Standard-on-Diskette and the file for the Standard on the distribution diskette should bealtered in any way. All of UL’s Standards and all copyrights, ownerships, and rights regarding thoseStandards shall remain the sole and exclusive property of UL.All rights reserved. No part of this publication may be reproduced, stored in a retrieval system, ortransmitted in any form by any means, electronic, mechanical photocopying, recording, or otherwisewithout prior permission of UL.Revisions of UL Standards for Safety are issued from time to time. A UL Standard for Safety is currentonly if it incorporates the most recently adopted revisions.UL provides this Standard ″as is″ without warranty of any kind, either expressed or implied, including butnot limited to, the implied warranties of merchantability or fitness for any purpose.In no event will UL be liable for any special, incidental, consequential, indirect or similar damages,including loss of profits, lost savings, loss of data, or any other damages arising out of the use of or theinability to use this Standard, even if UL or an authorized UL representative has been advised of thepossibility of such damage. In no event shall UL’s liability for any damage ever exceed the price paid forthis Standard, regardless of the form of the claim.UL will attempt to answer support requests concerning electronic versions of its Standards. However, thissupport service is offered on a reasonable efforts basis only, and UL may not be able to resolve everysupport request. UL supports the electronic versions of its Standards only if they are used under theconditions and operating systems for which it is intended. UL’s support policies may change fromtime-to-time without notification.

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 eachsingle-user version of an electronic Standard. Only one copy of the Standard may be printed for eachauthorized user of a multiple-user version of an electronic Standard. Because of differences in thecomputer/software/printer setup used by UL and those of electronic Standards purchasers, the printedcopy 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 beingviewed 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 theaffected item. The prior text for requirements that have been revised and that have a future effective dateare located after the Standard, and are preceded by a ″SUPERSEDED REQUIREMENTS″ notice.New product submittals made prior to a specified future effective date will be judged under all of therequirements in this Standard including those requirements with a specified future effective date, unlessthe applicant specifically requests that the product be judged under the current requirements. However, ifthe applicant elects this option, it should be noted that compliance with all the requirements in thisStandard will be required as a condition of continued Listing, Recognition, and Follow-Up Services afterthe effective date, and understanding of this should be signified in writing.Copyright 2000 Underwriters Laboratories Inc.This Standard consists of pages dated as shown in the following checklist:PageDate1-38 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
