38、n its Scope, it is important to notethat it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.OCTOBER 30, 2002 UL 60730-2-6 5Foreword (UL)A. This Standard contains basic requirements for products covered by Underwriters Laboratories Inc. (U

39、L)under its Follow-Up Service for this category within the limitations given 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, installatio

40、n, and usederived from consultation with and information obtained from manufacturers, 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 o

41、f this Standard by a manufacturer is one of the conditions of thecontinued 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

42、 impair the level ofsafety contemplated by these requirements.D. A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire or of electric shockor injury to persons sha

43、ll be evaluated using appropriate additional component and end-productrequirements to maintain the level of safety as originally anticipated by the intent of this standard. Aproduct whose features, characteristics, components, materials, or systems conflict with specificrequirements or provisions of

44、 this standard does not comply with this standard. Revision of requirementsshall be proposed and adopted in conformance with the methods employed for development, revision, andimplementation of this standard.E. UL, in performing its functions in accordance with its objectives, does not assume or und

45、ertake todischarge any responsibility of the manufacturer or any other party. The opinions and findings 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.
