12、age 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 me

13、t 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 aff

14、ected 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 re

15、spect 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 Standar

17、ds 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 CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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.

29、s and information. It provides normative references and offers brief explanations of the meaning or the application of some of the numerical data given on the individual lamp data sheets in Part II of this standard. It also provides requirements that are common to all mercury lamp types. Part II con

30、tains an individual data sheet for each size of mercury lamp. Part III contains the maximum outline drawings for each size of lamp. ANSI C78.40-2016 Page 1 2016 National Electrical Manufacturers Association Part I General Information 1 Scope This standard sets forth the physical and electrical requi

31、rements for single-ended metal halide lamps operated on 60 Hz ballasts to ensure interchangeability and safety. The data given also provides the basis for the electrical requirements for ballasts as well as the lamp-related requirements for luminaires. Luminous flux and lamp color are not part of th

32、is standard. 1.1 Important patent disclaimer At the time of publication, it is possible that some of the elements of this document may be the subject of patent rights. When this Standard was approved for publication, the National Electrical Manufacturers Association (NEMA) did not know of any patent

33、 applications, patents pending, or existing patents. NEMA shall not 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.

41、SI C82.9. 4 Methods of Measurement Measurement of the electrical characteristics and the bulb and base temperatures of mercury lamps shall be made in accordance with ANSI C78.389. 5 Lamp Specifications Lamps must meet the requirements contained within ANSI C78.62035 as well as the specifications con

42、tained in this standard. 6 Lamp Designations Mercury-lamp 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 may

43、 be a slash followed by a luminaire characteristic letter. Operating position limitations are as indicated on the lamp marking. 7 Bulb Designations Bulb designations are defined in ANSI C79.1. Due to the long term use of customary designations, they will continue to be used herein. Metric designatio

44、ns for bulbs are not given in this standard. 8 Base Specifications Screw-shell-type bases are specified in ANSI C81.61. 9 Maximum Outline Drawings The maximum outline drawings in Part III of this standard show for each bulb-base-MOL category the maximum limits of the space that may be occupied by an

45、y part of the bulb, assuming a fixed base position. They do not define the actual bulb shape. The limits shown take into account the maximum bulb dimensions and the possible eccentricity of the bulb with respect to the base. The dashed lines indicate typical bulb shapes. A lamp with its base in a fi

46、xed position shall remain within the limits of the outline in the relevant maximum outline drawing. Maximum outline drawings are produced in accordance with ANSI C78.30. 10 Electrical Characteristics 10.1 Lamp operating characteristics The lamp operating characteristics in part II of this standard a

47、pply to bare lamps operating on a reference ballast at an ambient temperature of 25C 5C (77F 9F). The values of lamp voltage, current, and ANSI C78.40-2016 Page 3 2016 National Electrical Manufacturers Association wattage shown on the individual lamp data sheets in Part II are those that apply after

48、 the lamps have been aged for 100 hours. The operating voltage of lamps tends to follow a normal distribution pattern. For all lamp types except the 700 W H35 and 1,000 W H36 types, at least 95% of all lamps produced can be expected to have an operating voltage within +10 V of nominal. For the 700 W

49、 H35 and 1,000 W H36 types, the operating voltage range for 95% of the lamps is +16 V from nominal. The voltage rise to end-of-life may approximate 1% for each 5,000 hours of operation. 10.2 Warm-up time Bare lamps operating in still air shall reach 95% of the minimum lamp operating voltage within the time limit and at the ambient temperature and current specified on the applicable lamp data sheet. Lamps shall meet this requirement in the burnin
