12、ge i 2016 National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by The American National Standards Institute, Inc. (ANSI) that the requirements for due process, consensus, and other criteria for approval have been met

13、 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 by directly, and materially affe

14、cted 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 an American National Standard does not in any res

15、pect preclude anyone, whether s/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, and the general public. The American National

16、Standards Institute, Inc., does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standard

17、s Institute, Inc. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on this title page. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute, Inc., require

18、that action be taken periodically to reaffirm, revise, or withdraw this standard.

42、nations Metal halide designations are assigned in accordance with ANSI C78.380. Note that the number (two or three digits) following the first upper case letter in the designation, indicates a unique set of electrical characteristics. Following the lamp number is a slash followed by a luminaire char

43、acteristic letter. Operating position limitations are indicated on the lamp marking. 5.1.2 Bulb Designation Bulb designations are defined in ANSI C78.79.
