14、uests concerning electronic versions of its Standards. However, this support 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 s
15、ystems for which it is intended. ULs support policies may change from time-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. P

17、ng an electronic Standard on the purchasers computer system. If a single-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
18、 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. 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
19、storage device of a multiple-user computer, or on an Intranet server. 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 on
20、e copy of the Standard may be printed from each single-user version of 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 thos
21、e of electronic Standards purchasers, the printed copy obtained by a purchaser may not look exactly like the on-line screen view or the printed Standard.
