4、33 Pfi ngsten Road Northbrook, IL 60062-2096 UL Standard for Safety for Particular Requirements for Battery-Operated Sanders, UL 745-4-4 Second Edition, Dated November 16, 2007 Summary of Topics This new Second edition was issued to clarify the UL effective date statement shown on the Preface page a
5、nd to make other administrative changes. The technical content of the First edition has been reproduced verbatim in this edition; the text of the standard has not been changed. As noted in the Commitment for Amendments statement located on the back side of the title page, UL and CSA are committed to
6、 updating this IEC-based binational standard jointly. However, this Second edition dated November 16, 2007 will not be issued by CSA since it addresses UL only administrative changes. The UL Foreword is no longer located within the UL Standard. For information concerning the use and application of t
7、he requirements contained in this Standard, the current version of the UL Foreword is located on ULStandardsInfoNet at: http:/ The master for this Standard at ULs Northbrook Office is the official document insofar as it relates to a UL service and the compliance of a product with respect to the requ
8、irements for that product and service, or if there are questions regarding the accuracy of this Standard. ULs Standards for Safety are copyrighted by UL.

14、om IHS -,-,- UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL UL will attempt to answer support requests concerning electronic versions of its Standards. However, this support service is offered on a reasonable efforts basis only, and UL may
15、not be able to resolve every support request. UL supports the electronic versions of its Standards only if they are used under the conditions and operating systems for which it is intended. ULs support policies may change from time-to-time without notifi cation. UL reserves the right to change the f
16、ormat, presentation, fi le types and formats, delivery methods and formats, and the like of both its printed and electronic Standards without prior notice. Purchasers of the electronic versions of ULs Standards for Safety agree to defend, indemnify, and hold UL harmless from and against any loss, ex
17、pense, 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 Stand
18、ard 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 concurrent ac
19、cess. 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 autho
20、rized. 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
21、 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 printed
22、 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 elements o
23、f the Standard having future effective dates as indicated in the preface. 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 specifi
24、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, if the applicant elects this op
25、tion, it should be noted that compliance with all the requirements in this Standard will be required as a condition of continued Listing, Recognized and Follow-Up Services after the effective date, and understanding of this should be signifi ed in writing.
