8、Roof Covering Materials, UL 997 for Fifth Edition, Dated May 31, 1995 Revisions: This Standard contains revisions through and including July 22, 1998. UL is in the process of converting its Standards for Safety to the Standard Generalized Markup Language (SGML). SGML - - an international standard (I
9、S0 8879-1986) - - is a descriptive markup language that describes a documents structure and purpose, rather than its physical appearance on the page. The more significant benefits that will result from ULs use of SGML are increased productivity and reduced turnaround times; and data and information
10、consistency, reusability, shareability, and portability. The changes contained in these revised pages are needed to modify the format and layout of this Standard to allow it to be converted to SGML. These are editorial changes now in effect. A change is indicated by a note following the affected ite
11、m. The note is preceded and followed by an asterisk. The revisions dated July 22, 1998 include a reprinted title page (page 1) for this Standard. As indicated on the title page (page I), this UL Standard for Safety has been adopted by the Department of Defense. The master for this Standard at ULs No
12、rthbrook Office 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.

However, this support service is offered on a reasonable efforts basis only, and UL ma
19、y not be able to resolve every support request. UL supports a Standards-on-Diskette only if it is used under the conditions and operating systems for which it is intended. ULs support policies may change from time-to-time without notification. UL reserves the right to change the format, presentation
20、, 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 defend, indemnify, and hold UL harmless from and against any loss, expense, liability, damage, claim, or judgement (includ
21、ing 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-user version Standards-on-Diskette was purchased, one copy of this Standard may be stored on the hard disk of a single pers
22、onal 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 a time and for which there is no possibility of multiple concurrent access. The original distribution diskette should be s
23、tored 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 storage device of a multiple-user computer. The number of concurrent users shall not exceed the number of users authorized fo
24、r 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 the requirements of a Standard, conducting a word search, and the like. Only one copy of the Standard may be printed from
25、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. An employee of an organization purchasing a Standard-on-Diskette can make a copy of the page or pages being viewed for the
26、ir own fair and/or practical internal use. Because of differences in the computer/software/printer setup used by UL and those of Standards-on-Diskette purchasers, the printed copy obtained by a purchaser may not look exactly like the on-line screen view or the printed Standard. The requirements in t
27、his 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 note following the affected item. The prior text for requirements that have been revised and that have a future effective da
28、te 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 under all of the requirements in this Standard including those requirements with a specified future effective date, unless
29、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 with all the requirements in this Standard will be required as a condition of continued Listing and Follow-Up Services after
30、 the effective date, and understanding of this should be signified in writing.

This Standard contains a description of the basic test method(s) for evaluating products covered by Underwrite
44、rs Laboratories Inc. (UL) under its Follow-Up Service for this category within the limitations given below and in the Scope section of this Standard. This test method(s) is based upon sound engineering principles, research, records of tests and field experience, and an appreciation of the problems o
45、f manufacture, installation, and use derived from consultation with and information obtained from manufacturers, users, inspection authorities, and others having specialized experience. It is subject to revision as further experience and investigation may show is necessary or desirable. B. The consi
46、stent and uniform production of the product so that it will perform in the manner indicated by the coverage is one of the conditions of the continued coverage of the manufacturers product. C. A product which performs in a specified manner will not necessarily be judged to be eligible for coverage if
47、, when examined and tested, it is found to have other features which impair the significance associated with such performance. D. UL, in performing its functions in accordance with its objectives, does not assume or undertake to discharge any responsibility of the manufacturer or any other party. Th
48、e opinions and findings of UL represent its professional judgment given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. UL shall not be responsible to anyone for the use of or reliance upon this Standard by anyone
49、. UL shall not incur any obligation or liability for damages, including consequential damages, arising out of or in connection with the use, interpretation of, or reliance upon this Standard. E. Many tests required by the Standards of UL are inherently hazardous and adequate safeguards for personnel and property shall be employed in conducting such tests.
