37、he users of the Standard to judge its suitability for their particular purpose.JANUARY 16, 2004 UL 60730-2-18 5Foreword (UL)A. This Standard contains basic requirements for products covered by Underwriters Laboratories Inc. (UL)under its Follow-Up Service for this category within the limitations giv

38、en below and in the Scope sectionof this Standard. These requirements are based upon sound engineering principles, research, records oftests and field experience, and an appreciation of the problems of manufacture, installation, and usederived from consultation with and information obtained from man

39、ufacturers, users, inspection authorities,and others having specialized experience. They are subject to revision as further experience andinvestigation may show is necessary or desirable.B. The observance of the requirements of this Standard by a manufacturer is one of the conditions of thecontinued

40、 coverage of the manufacturers product.C. A product which complies with the text of this Standard will not necessarily be judged to comply withthe Standard if, when examined and tested, it is found to have other features which impair the level ofsafety contemplated by these requirements.D. A product

41、 employing materials or having forms of construction which conflict with specific requirementsof the Standard cannot be judged to comply with the Standard. A product employing materials or havingforms of construction not addressed by this Standard may be examined and tested according to the intentof

42、 the requirements and, if found to meet the intent of this Standard, may be judged to comply with theStandard.E. UL, in performing its functions in accordance with its objectives, does not assume or undertake todischarge any responsibility of the manufacturer or any other party. The opinions and fin

43、dings of ULrepresent its professional judgment given with due consideration to the necessary limitations of practicaloperation and state of the art at the time the Standard is processed. UL shall not be responsible to anyonefor the use of or reliance upon this Standard by anyone. UL shall not incur

44、any obligation or liability fordamages, including consequential damages, arising out of or in connection with the use, interpretation of,or reliance upon this Standard.F. Many tests required by the Standards of UL are inherently hazardous and adequate safeguards forpersonnel and property shall be em

The difference type is noted on the first lineof the National Diffe

47、rence in the standard. The standard may not include all types of these NationalDifferences.DR These are National Differences based on the National Electrical Code (NEC) and other U.S.Regulatory Requirements.D1 These are National Differences which are based on basic safety principles and requirements

48、,elimination of which would compromise safety for U.S. consumers and users of products.D2 These are National Differences based on safety practices. These are differences for IECrequirements that may be acceptable, but adopting the IEC requirements would require considerableretesting or redesign on t
