16、erver, 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. Electronic Standards are intended for on-line use, such as for viewing the requirements of a Standard, conducting a word se
17、arch, 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 authorized user of a multiple-user version of an electronic Standard. Because of differences in the computer/software/printe
18、r 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 Standard. An employee of an organization purchasing a UL Standard can make a copy of the page or pages being viewed for their own
19、 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 Standard having future effective dates as indicated in the preface. The prior text for requirements that have been revised a
20、nd that have a future effective date are located after the Standard, and are preceded by a SUPERSEDED REQUIREMENTS notice.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 specifi ed future effective date will be judged under all of the requirements in this Standard including those requirements with a specifi
21、 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, it should be noted that compliance with all the requirements in this Standard will be required as a condition of continued L
22、isting, Recognition, and Follow-Up Services after the effective date, and understanding of this should be signifi ed in writing.
