This Standard contains basic requirements for products covered by Underwriters Laboratories Inc. (UL) under its Follow-Up Service for this category withi

31、n the limitations given below and in the Scope section of this Standard. These requirements are based upon sound engineering principles, research, records of tests and field experience, and an appreciation of the problems of manufacture, installation, and use derived from consultation with and infor

32、mation obtained from manufacturers, users, inspection authorities, and others having specialized experience. They are subject to revision as further experience and investigation may show is necessary or desirable. B. The observance of the requirements of this Standard by a manufacturer is one of the

33、 conditions of the continued coverage of the manufacturers product. C. A product which complies with the text of this Standard will not necessarily be judged to comply with the Standard if, when examined and tested, it is found to have other features which impair the level of safety contemplated by

34、these requirements. D. A product employing materials or having forms of construction which conflict with specific requirements of the Standard cannot be judged to comply with the Standard. A product employing materials or having forms of construction not addressed by this Standard may be examined an

35、d tested according to the intent of the requirements and, if found to meet the intent of this Standard, may be judged to comply with the Standard. E. UL, in performing its functions in accordance with its objectives, does not assume or undertake to discharge any responsibility of the manufacturer or

36、 any other party. The 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 thi

37、s Standard by anyone. 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. F.

A product whose features, characteristics, components, materials, or systems conflict with

43、specific requirements or provisions of this standard cannot be judged to comply with this standard. Where considered appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard. 2 Units of

44、 Measurement 2.1 If a value for measurement is followed by a value in other units in parentheses, the second value may be only approximate. The first stated value is the requirement. 3 Component 3.1 Except as indicated in 3.2, a component of a product covered by this standard shall comply with the r

45、equirements for that component. 3.2 A component need not comply with a specific requirement that: a) Involves a feature or characteristic not needed in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 3.3 A component sha

46、ll be used in accordance with its recognized rating established for the intended conditions of use. 3.4 Specific components are recognized as being incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such

47、as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions for which they have been recognized.
