12、AN 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 by the standards developer. An American National Standard imp
13、lies 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 affected interests. Substantial agreement means much more than a s
14、imple 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 respect preclude anyone, whether s/he has approved the standard o
15、r 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 Standards Institute, Inc., does not develop standards and will
16、 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 Standards Institute, Inc. Requests for interpretations should be addre
17、ssed 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 CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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 that action be taken periodically to reaffirm, revise, or with

26、rect replacements for existing ANSI standardized non-LED lamps. Lamps covered in this standard contain LED-based light sources. OLED lamps are not included at this time. 2 Purpose The purpose of the designation system covered by this standard is to provide an identification code for use in ANSI stan
27、dards. Some lamp marking requirements are also identified. Guidance is given as to which characteristics are essential to assure interchangeability for safe operation and which characteristics affect performance. The lamp characteristic data given by a manufacturer on an LED (Light-Emitting Diode) D

They have not been approved by the American National Standards Institute (ANSI) and do not constitute an American National Standard. Similarly, any consolidated listing of assigned designation
29、s with associated characteristics does not constitute an American National Standard. 3 References The following standards contain provisions that, through reference in this text, constitute provisions of this American National Standard.
