17、 9275795 Ob93697 444 W 4 SUBJECT 139 JULY 18,1997 FOREWORD A. This Outline of Investigation contains basic requirements for products covered by Underwriters Laboratories Inc. (UL) under its Follow-Up Service for this category within the limitations given below and in the Scope section of this Outlin
18、e of Investigation. They are subject to revision as further experience and investigation may show is necessary or desirable. B. The observance of these requirements by a manufacturer is one of the conditions of the continued coverage of the manufacturers product. C. A product which complies with the
19、 text of this Outline of Investigation will not necessarily be judged to comply with the Outline of Investigation if, when examined and tested, it is found to have other features which impair the level of safety contemplated by these requirements. D. A product employing materials or having forms of
20、construction differing from those detailed in the requirements of this Outline of Investigation may be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be judged to comply with the Outline of Investigation. E. UL, in performing its fun
21、ctions in accordance with its objectives, does not assume or undertake to discharge any responsibility of the manufacturer or 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 stat
22、e of the art at the time the Outline of Investigation is processed. UL shall not be responsible to anyone for the use of or reliance upon this Outline of Investigation by anyone. UL shall not incur any obligation or liability for damages, including consequential damages, arising out of or in connect
23、ion with the use, interpretation of, or reliance upon this Outline of Investigation. F. Many tests required by the Outline of Investigations of UL are inherently hazardous and adequate safeguards for personnel and property shall be employed in conducting such tests.
