3、i ngsten Road Northbrook, IL 60062-2096 UL Standard for Safety for Power-Operated Dispensing Devices for Petroleum Products, UL 87 Eleventh Edition, Dated October 31, 2001 UL Standards for Safety are developed and maintained in the Standard Generalized Markup Language (SGML). SGML - an international
4、 standard (ISO 8879-1986) - is a descriptive markup language that describes a documents structure and purpose, rather than its physical appearance on a page. Due to formatting differences resulting from the use of ULs new electronic publishing system, please note that additional pages (on which no r
5、equirements have been changed) may be included in revision pages due to relocation of existing text and reformatting of the Standard. As indicated on the title page (page1), this UL Standard for Safety has been adopted by the Department of Defense. The master for this Standard at ULs Northbrook Offi
6、ce is the official document insofar as it relates to a UL service and the compliance of a product with respect to the requirements for that product and service, or if there are questions regarding the accuracy of this Standard.

11、f the possibility of such damage. In no event shall ULs liability for any damage ever exceed the price paid for this Standard, regardless of the form of the claim.

15、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 copy of th
16、is 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 multiple concu
17、rrent 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 number of use
18、rs 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 may be pri
19、nted 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 view or the
20、 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 other el
21、ements of the Standard having future effective dates as indicated in the note 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 su
22、bmittals 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. However
23、, 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, Recognition, and Follow-Up Services after the effective date, and understanding of this should be signifi ed in writing.
