2、 dimensions and centering system Secretariat National Electrical Manufacturers Association Approved July 22,1997 American National Standards Institute, Inc. American Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other cr

3、iteria for approval have been met by the standards developer. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached

4、 by National standard directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The existence of

5、 an American National Standard does not in any respect preclude anyone, whether he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. It is intended as a guide to aid the manufacturer, the consumer

21、 holding system will be assured. These lamps provide a reference for mounting at the lamps reflector rim. Since lamp location is controlled at the reflector rim, the dimensions of the centering device of the holding system are also covered. Both the lamps rim and the centering device specified in th
