19、STD*UL b03-ENGL 1778 9275795 077Lb50 781 tr2 March 2,1999 - UL 603 UL reserves the right to change the format, presentation, 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
20、 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 a Standard-on-Diskette on the purchasers computer system. If a single-
21、user version Standards-on-Diskette was purchased, one copy of this Standard may be stored on the hard disk of a single 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
22、 a time and for which there is no possibility of multiple concurrent access. The original distribution diskette should 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 st
23、orage device of a multiple-user computer. The number of concurrent users shall not exceed the number of users authorized 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
24、 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 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
25、. An employee of an organization purchasing a Standard-on-Diskette can make a copy of the page or pages being viewed for their own fair and/or practical internal use. Because of differences in the computer/sohare/printer setup used by UL and those of Standards-on-Diskette purchasers, the printed cop
26、y obtained by a purchaser may not look exactly like the on-line screen view or the printed Standard. The requirements 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 no
27、te following the affected item. The prior text for requirements that have been revised and that have a future effective 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 u
28、nder all of the requirements in this Standard including those requirements with a specified future effective date, unless the applicant specifically requests that the product be judged under the current requirements. However, if the applicant elects this option, it should be noted that compliance wi
29、th 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 signified in writing.
