However, this support service is offered on a reasonable efforts basis o
15、nly, 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 time-to-time without notifi cation. UL reserves the right
16、 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 to defend, indemnify, and hold UL harmless from and agai
17、nst 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 single-user version electronic Standard was purchased, one co
18、py 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 at a time and for which there is no possibility of multip
19、le 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. The number of concurrent users shall not exceed the numbe
20、r 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 an electronic Standard. Only one copy of the Standard ma
21、y 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 purchaser may not look exactly like the on-line screen vie
22、w 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. The requirements in this Standard are now in effect, except for those paragraphs, sections, tables, fi gures, and/or
23、other elements of the Standard having future effective dates as indicated in the note following the affected item.

24、oduct submittals made prior to a specifi ed future effective date will be judged under all of the requirements in this Standard including those requirements with a specifi ed future effective date, unless the applicant specifi cally requests that the product be judged under the current requirements.
25、 However, if the applicant elects this option, it should be noted that compliance with all the requirements in this Standard will be required as a condition of continued Listing and Follow-Up Services after the effective date, and understanding of this should be signifi ed in writing.
