This Standard contains basic requirements for products covered by Underwriters Laboratories Inc. (UL)under its Follow-Up Service for this category
26、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, installation, and usederived from consultation with and inf
27、ormation 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 of this Standard by a manufacturer is one of the
28、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 impair the level ofsafety contemplated by these
29、 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 shall be evaluated using appropriate additional com
30、ponent 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 this standard does not comply with this standar
31、d. 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 undertake todischarge any responsibility of the man
32、ufacturer or any other party.
