(UL) 333 Pfi ngsten Road Northbrook, IL 60062-2096 UL Standard for Safety for Drinking-Water Coolers, UL 399 Sixth Edition, Dated June 25, 1993 Revisions: This Standard contains revisions through and
3、 including March 3, 2006. Summary of Topics These editorial revisions to ANSI/UL 399 replace all references to UL 1020, the Standard for Thermal Cutoffs for Use in Electrical Appliances and Components, with reference to UL 60691, the Standard for Thermal-Links Requirements and Application Guide. UL
4、1020 was withdrawn and superseded by UL 60691. 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 and purpose, rather than it
5、s 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 S
6、tandard. 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 eff
7、ective. The following table lists the future effective dates with the corresponding item.

The revisions dated March 3, 2006 editorially replace all references to UL 1020 with the reference to UL 60691. As indicated on the title page (page 1), this UL Standard for S
9、afety 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. For information concerning the use a
10、nd 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 and the compliance of a product with
11、respect to the requirements for that product and service, or if there are questions regarding the accuracy of this Standard.

No part of this publication may be reproduced, stored in a retrieval system, or transmitted in any form by any means, electronic, mechanical photocopying, recording, or otherwise without prior permission of UL. Revisions of UL Standards for Safety
14、are issued from time to time. A UL Standard for Safety is current only if it incorporates the most recently adopted revisions. UL provides this Standard as is without warranty of any kind, either expressed or implied, including but not limited to, the implied warranties of merchantability or fi tnes
15、s for any purpose. 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 repre
16、sentative has been 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 su
17、pport 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 t
18、ime-to-time without 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
19、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 singl
20、e-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 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 a
21、t 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 fi le-server, or on the permanent storage device of a multiple-user computer, or on an Intranet server. T
22、he 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
23、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 pu
24、rchaser 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.
