4、, products, equipment, constructions, methods, and systems affecting such hazards. UL Standards for Safety are developed under a procedure which provides for participation and comment from the affected public as well as industry. The procedure takes into consideration a survey of known existing stan
5、dards and the needs and opinions of a wide variety of interests concerned with the subject matter of the standard. Thus manufacturers, consumers, individuals associated with consumer-oriented organizations, academicians, government officials, industrial and commercial users, inspection authorities,

8、quipment and Liquid Concentrates, UL 162 Seventh Edition, Dated March 30, 1994 Revisions: This Standard contains revisions through and including September 8, 19 199. UL is in the process of converting its Standards for Safety to the Standard Generalized Markup Language (SGML), and implementing an SG
9、ML compliant document management and publishing system. SGML - an international standard (IS0 8879-1986) - is a descriptive markup language that describes a documents structure and purpose, rather than its physical appearance on a page. Significant benefits that will result from ULs use of SGML and
10、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 ULs new electronic publishing system differ from that of ULs previous publishing sys
11、tem. Consequently, when revision pages are issued for a Standard with the new publishing system, these differences may result in the printing of pages on which no requirements have been changed - these additional pages result from relocation of text due to repagination and reformatting of the Standa
12、rd with the new publishing system. 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 chang
13、ed requirement becomes effective. The revisions dated September 8, 1999 include a reprinted title page (pagel) for this Standard. The revisions dated September 8, 1999 were issued for editorial corrections. These corrections include any combination of the following: Updated Foreword (item D); Update
14、d Scope; title changes to UL 489 and/or UL 1950; Withdrawn standards, UL 519 and UL 547, being replaced by UL 21 11 ; Removal of the “94 flammability classification. these revisions may also include other miscellaneous editorial corrections.

20、al, 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 the inability to use this Standard, even if UL or an authorized UL representative has been advised of the possibility of such damage. In no event s

UL will attempt to answer support requests concerning Wordperfect, Envoy, and Standards-on-Diskette. However, this support service is offered on a reasonable efforts basis only, and U
22、L may not be able to resolve every support request. UL supports a Standards-on-Diskette only if it is used under the conditions and operating systems for which it is intended. ULs support policies may change from time-to-time without notification. UL reserves the right to change the format, presenta
23、tion, file types and formats, delivery methods and formats, and the like of both its printed and electronic Standards without prior notice. Standards-on-Diskette purchasers agree to defend, indemnify, and hold UL harmless from and against any loss, expense, liability, damage, claim, or judgement (in
24、cluding reasonable attorneys fees) resulting from any error or deviation introduced while purchaser is storing a Standard-on-Diskette on the purchasers computer system. If a single-user version Standards-on-Diskette was purchased, one copy of this Standard may be stored on the hard disk of a single
25、personal computer, or on a single LAN file-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. The original distribution diskette should
26、be stored in a safe place. If a multiple-user version Standards-on-Diskette was purchased, one copy of the Standard may be stored on a single LAN file-server, or on the permanent storage device of a multiple-user computer. The number of concurrent users shall not exceed the number of users authorize
27、d for the Standards-on-Diskette version. The original distribution diskette should be stored in a safe place. Standards-on-Diskette 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 f
28、rom each single-user version of a Standards-on-Diskette. Only one copy of the Standard may be printed for each authorized user of a multiple-user version of a Standards-on-Diskette. An employee of an organization purchasing a Standard-on-Diskette can make a copy of the page or pages being viewed for
29、 their own fair and/or practical internal use. Because of differences in the computer/software/printer setup used by UL and those of Standards-on-Diskette purchasers, the printed copy obtained by a purchaser may not look exactly like the on-line screen view or the printed Standard. The requirements
30、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 the affected item. The prior text for requirements that have been revised and that have a future effectiv
31、e date are 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 the requirements in this Standard including those requirements with a specified future effective date, unle
