(ANSI) that the requirement
13、s for due process, consensus, and other criteria 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 Revi
14、ew, substantial agreement has been reached by 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 res
15、olution. The existence of an American National Standard does not in any respect 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.

32、 (R2016) Page 1 2016 National Electrical Manufacturers Association Organization of this Standard This standard has been arranged in four parts: Part I covers general requirements and information. It provides normative references and offers brief explanations of the meaning or the application of some
33、 of the numerical data given on the individual lamp data sheets in Part IV of this standard. It also provides requirements that are common to all high-pressure sodium (HPS) lamp types. Part II contains three appendices which provide a) a method for determining trapezoidal diagrams, b) a method for d
34、etermining dropout voltages, and c) a cross-reference list of the old ANSI C78.1350-series of standards. Part III contains the maximum outline drawings of each lamp size. Part IV contains individual lamp data sheets, which provide the specific lamp, ballast, and luminaire requirements of each HPS la
35、mp type. ANSI C78.42-2009 (R2016) Page 2 2016 National Electrical Manufacturers Association I. General Requirements and Information 1. Scope This standard sets forth the physical and electrical requirements for HPS lamps, to ensure performance and interchangeability. The data given also provide the
36、basis for the electrical requirements for ballasts and ignitors, as well as the lamp-related requirements for luminaires. This standard covers only single-ended HPS lamps. Lamps with internal starting devices are not covered. This standard does include “improved color“ HPS lamps (those lamps that ha
37、ve a color rendering index 60 and that operate on the same ballasts as the conventional lamps that they are intended to replace). However, color is not a standardized parameter. Luminous flux is not a standardized parameter either. This standard covers only 60 Hz operation of HPS lamps, on ballasts
38、designed for HPS lamps. 1.1 Important patent disclaimer It is possible that some of the elements of this document may be the subject of patent rights. When this document was approved for publication, ANSLG did not know of any patent applications, patents pending, or existing patents. ANSLG shall not
39、 be held responsible for identifying any or all such patent rights. 2. Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All s
40、tandards are subject to revision, and parties to agreements based on this American National Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

Methods of measurement Measurement of the electrical characteristics and the bulb and base temperatures of HPS lamps shall be made in accordance with ANSI C78.389. Measurement of the electrical character
46、istics of high-intensity discharge lamp ballasts shall be made in accordance with ANSI C82.6. 5. Lamp specifications 5.1 Lamp designations and descriptions 5.1.1 Lamp designations High-pressure sodium lamp designations used within this standard are assigned in accordance with ANSI C78.380. Note that
47、 the number (two or three digits) following the first letter in the designation (S for high pressure sodium), indicates a unique set of electrical characteristics. After the number is a slash followed by a luminaire characteristic letter. Single-ended high-pressure sodium lamps are typically permitt
48、ed for use in open luminaires and have a luminaire characteristic code of “O”. Markings on high-pressure sodium lamps only need to include the first two parts of the code, e.g. S68. Alternatively, some manufacturers may choose to include the luminaire characteristic, e.g. S68/O. Consult ANSI C78.380
49、 for additional details and information on other optional characteristic codes. ANSI C78.42-2009 (R2016) Page 4 2016 National Electrical Manufacturers Association 5.1.2 Bulb designations Bulb designations are defined in ANSI C79.1. Due to the long- term use of the conventional method of designation, its use will continue in this standard with the metric designation in parenthesis. In Part IV of this standard, an “E“ bulb designation includes E-, ED-, a
