7、 Standard Approval 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 sc

15、C78.81-2010) Suggestions for improvement of this standard will be welcome. They should be sent to the Secretariat, C78 Committee, American National Standard Lighting Group, 1300 North 17thStreet, Suite 1752, Rosslyn, VA 22209. This standard was processed and approved for submittal to ANSI by Accredi

16、ted Standards Committee on Electric lamps, C78, and its Work Group, C78WG02. Approval of the standard does not necessarily imply that all work group members voted for its approval. This revision supersedes ANSI_IEC C78.81-2005. This revision also includes removal of “.IEC.” from the standard number

17、designation. The acronym “IEC” was removed because it is copyright-protected in accordance with the latest edition of IEC Guide 21. This standard features the following revisions: 1. 25-Watt, 48-Inch T8, HF Fluorescent Lamp 7881-ANSI-1028-1 2. 28-Watt, 48-Inch T8, HF Fluorescent Lamp 7881-ANSI-1029-

18、1 3. 30-Watt, 48-Inch T8, HF Fluorescent Lamp 7881-ANSI-1030-1 You will note that for your ease of reference, in part IV, clause 3, there is a summary table of all lamp data sheets. The lamp data sheets for this table follow the convention set forth in part IV, clause 2. This organization groups lam

19、ps by circuit family, then orders them according to bulb diameter, nominal wattage, and nominal length. The datasheets found in part IV are arranged in datasheet number sequence. Information concerning approval of this standard is based on the documents listed in the table below. Amendment / Change

25、ents 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 electronic high frequency circuits. Some data sheets may specify more than one circuit application. Spec

26、ifications 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, circular, square shaped and U-shaped are found in ANSI C78.901. Lamps for conventional systems r

27、elying 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 in this standard may be similar to those in IEC 60081. However, additional types are included tha

28、t are used only in North America and are not specified in the IEC standard. 1.1 Important patent disclaimer The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard.

All standards 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. 2 General There are four parts to this standard: Part I Contains r

30、equirements 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 principles of dimensioning lamps, both as finished lamps and for maximum outline purposes. Part II Contains dimensioning prin

31、ciples and lamp outline drawings. Part III Contains the annexes. Part IV Contains the lamp data sheets for the lamp classes covered in this standard.

Those used on th

38、e 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 from IEC publication 60081. These sheets do not contain a lamp abbreviation per Annex A

39、. 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 standard shall be made in accordance with the lamp measurements standard (ANSI C78.3

40、75). 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 reference ballast standard requires a power factor of 0.0750.005 for all fluorescent refer

41、ence 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 Part II are product drawings that show the applications of the various coded dimension

42、s 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 made to provide maximum outline drawings to show the space occupied by the lamps. They

43、 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 type on more than one type of circuit. In such cases, the lamp data sheet will show t

44、he information for all of the appropriate circuits.

45、ary 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 standard maintains that practice. For example, a 1-inch diameter bulb

46、 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 ANSI C81.61. Standard sheets for the gauges for checking bases are includ

47、ed 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 are not internally shorted. 10.3 Lamp dimensions 10.3.1 Base alignment

48、 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 alignment of lamps with G5 miniature bipin bases Both pins (excluding fl

49、anges) 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 respect 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 longitudinally to receive the
