3、oval of an American National Standard requires verification by ANSI that the requirements 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 provis

4、ions. 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 simple majority, but not necessarily unanimity. Consensus requires that all v

5、iews 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 or not, from manufacturing, marketing, purchasing, or using products, process

6、es, 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 does not develop standards and will in no circumstances give an interpretation of any American National Standard. More

7、over, 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. Requests for interpretations should be addressed to the Committee Secretariat referred to on the title page. CAUTION NOTICE: This Am

8、erican National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all sta

22、ational Electrical Manufactuers Association Page 7 of 201 PART I General Information and Requirements 1 Scope This standard sets forth the physical and electrical characteristics of the principal types of fluorescent lamps intended for application on conventional line frequency circuits, and electro

23、nic high frequency circuits. Some data sheets may specify more than one circuit application. Specifications for both the lamp itself and the interactive features of the lamp and ballast are given. Only double-based lamps of the regular linear shape are included. Single-based lamps including compact,

24、 circular, square shaped and U-shaped are found in ANSI C78.901. Lamps for conventional systems relying on auxiliary support from external ballasts are described. These lamps are those designed for 60-Hz and/or high frequency operation. Lamp color is not specified herein. Certain lamp types covered

25、in this standard may be similar to those in IEC 60081. However, additional types are included that are used only in North America and are not specified in the IEC standard. 1.1 Important patent disclaimer At the time of publication, it is possible that some of the elements of this document may be th

26、e subject of patent rights. When this Standard was approved for publication, the American National Standards Lighting Group (ANSLG) and the National Electrical Manufacturers Association (NEMA) did not know of any patent applications, patents pending, or existing patents. ANSLG shall not be held resp

27、onsible for identifying any or all such patent rights. 2 General There are four parts to this standard: Part I Contains requirements and general information. Detailed descriptions, references, and explanations of the terms used in the lamp data sheets are given in this part. It also defines the prin

28、ciples of dimensioning lamps, both as finished lamps and for maximum outline purposes. Part II Contains dimensioning principles and lamp outline drawings. Part III Contains the annexes. Part IV Contains the lamp data sheets for the lamp classes covered in this standard. Sheets adopted from IEC are n

29、ot included but a source reference is listed.Part I ANSI C78.812013 Revision of ANSI C78.81-2010 2014 National Electrical Manufactuers Association Page 8 of 201 3 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this Amer

35、not officially assigned through any administered designation system. Those used on the data sheets are assigned in accordance with the Guidelines of Annex A. There is no requirement for the use of these abbreviations for lamp marking. For some lamp types the referenced data sheet has been adopted fr

36、om IEC publication 60081. These sheets do not contain a lamp abbreviation per Annex A. They are marked with an IEC designation code (ILCOS), but that code is not used in the USA. 6 Methods of measurement Electrical measurements necessary to determine the performance of lamps that are defined in this

37、 standard shall be made in accordance with the lamp measurements standard (ANSI C78.375). 7 Reference ballasts Reference ballasts used for measurements of fluorescent lamps shall meet the general requirements set forth in the reference ballast standard (ANSI C82.3). It should be noted that the refer

38、ence ballast standard requires a power factor of 0.0750.005 for all fluorescent reference ballasts, unless otherwise specified on a lamp data sheet. Also, note that rapid-start reference ballasts called for in this standard include 3.6 V cathode heating. 8 Product drawings The drawings included in P

39、art II are product drawings that show the applications of the various coded dimensions that appear on the data sheets. Drawings are only needed to depict families of lamps; the particular values vary within a family in accordance with the values on the relevant lamp data sheet. No attempt has been m

40、ade to provide maximum outline drawings to show the space occupied by the lamps. They are not provided because the need for such has not been established. 9 Application of lamps on more than one type of circuit Lamp manufacturers may form an industry consensus approving the use of a particular lamp

41、type on more than one type of circuit. In such cases, the lamp data sheet will show the information for all of the appropriate circuits. ANSI C78.812013 Revision of ANSI C78.81-2010 2014 National Electrical Manufactuers Association Page 10 of 201 10 Lamp physical and dimensional requirements 10.1 Bu

42、lb specifications Each lamp data sheet in Part IV specifies the necessary bulb shape and tube diameter. Bulb shapes are defined in the bulb nomenclature standard (ANSI C79.1). Due to the long established practice of referring to the diameter of fluorescent lamp bulbs in eighth-of-an-inch units, this

43、 standard maintains that practice. For example, a 1-inch diameter bulb is called a T8 bulb. Metric diameters in millimeters are shown in parentheses immediately following the customary designation. 10.2 Base specifications Bases on finished lamps shall comply with the standard sheets included in ANS

44、I C81.61. Standard sheets for the gauges for checking bases are included in ANSI C81.63 and its supplements. For instant-start lamps with medium or mogul bipin bases, the pins are internally shorted. Some rapid-start lamps are used with high frequency instant-start ballasts. The pins of these lamps

45、are not internally shorted. 10.3 Lamp dimensions 10.3.1 Base alignment of finished lamps Finished lamps shall comply with the dimensions specified on the relevant data sheet in Part IV. Graphical definitions of the dimensional code letters used on the data sheets are given in Part II. 10.3.2 Base al

46、ignment of lamps with G5 miniature bipin bases Both pins (excluding flanges) of the two bases of an assembled lamp shall pass simultaneously without binding through parallel slots, each 0.113 in (2.87mm) in width, suitably spaced longitudinally to receive the lamp. The offset of the bulb with respec

47、t to the base axis shall comply with Table 1. 10.3.3 Base alignment of lamps with G13 medium bipin bases Both pins (excluding flanges) of the two bases of an assembled lamp shall pass simultaneously without binding through parallel slots, each 0.120 inch (3.05 mm) in width, suitably spaced longitudi

48、nally to receive the lamp. The offset of the bulb with respect to the base axis shall comply with Table 1. 10.3.4 Base alignment of lamps with R17d recessed double-contact bases Both base bosses of an assembled lamp shall pass simultaneously without binding through parallel slots each 0.25 inch (6.3

49、5mm) deep and 0.363 inch (9.22mm) in width, suitably spaced longitudinally to receive the lamp with the bottoms of the slots against the boss ends. The offset of the bulb with respect to the base axis shall comply with Table 1. 10.3.5 Base alignment of lamps with Fa8 single pin bases The offset of the bulb with respect to the base axis is represented by dimension T described in Figure 1.
