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 tness for any purpose. In no event will UL be
18、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 representative has been advised of the possibil

23、 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 copy of this Standard ma
24、y 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 multiple concurrent access.
25、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 number of users authorized.
26、 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 may be printed for each
27、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 view or the printed Stand
28、ard. 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 other elements of the

New product submittals made prior to a specifi ed fut
30、ure 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. However, if the applicant elects this option,
31、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.
