This standard was processed and ap
15、proved by Accredited Standards Committee on Electric Lamps, C78, and its Work Group, C78WG02. Work Group approval of the standard does not necessarily imply that all Work Group members voted for its approval. The revised edition supersedes ANSI_IEC C78.901-2005. This revision includes the removal of
16、 “IEC” from the standard number designation. The acronym “IEC” was removed because it is copyright-protected in accordance with the latest edition of IEC Guide 21. Please see this entire standard for revisions and additions. DEDICATION: Edward Eugene Hammer 1931 2012 Who helped lay the foundation fo

21、Information and Requirements 1. Scope This standard sets forth the physical and electrical characteristics required to assure the interchangeability and to assist in the proper application of single-based fluorescent lamps. Single-based compact fluorescent lamps, both self-supporting and those requi
22、ring auxiliary support, including circular, square and U-shaped lamps are specified. Specifications for both the lamp itself and the interactive features of the lamp with the ballast are given. Information for luminaire design is given for certain lamp types. The lamps covered in this standard are i
23、ntended for use with external ballasts as described. These lamps are designed for 60Hz and/or high frequency operation. Many of the lamp types covered in this standard are closely comparable to those specified in IEC 60901. 1.1 Important Patent Disclaimer At the time of publication, it is possible t
24、hat 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 applications, patents pending, or existing patents. NEMA shall not be held responsible f
25、or 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 principles o
26、f 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 all of the lamp data sheets for the lamp classes covered in this standard. C78.901-2014 Page 2 2014 Natio

Definitions For related definitions see ANSI C82.13 and the electrical dictionary ANSI/
34、IEEE 100. 5. Lamp Abbreviations Lamp abbreviations for fluorescent lamps are not officially assigned through any administered designation system. Those used on the data sheets in Part IV are assigned in accordance with the guideline of Annex B. There is no requirement for the use of these abbreviati
35、ons for lamp marking. For some lamp types the referenced data sheet has been adopted from IEC publication 60901. These sheets do not contain a lamp abbreviation per Annex B. They are marked with an IEC designation code (ILCOS), but that code is not used in the USA. 6. Methods of Measurement Electric
36、al measurements necessary to determine the performance of lamps defined in this 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
37、 the reference ballast standard, ANSI C82.3. It should be noted that the reference ballast standard requires a power factor of 0.075 +/- 0.005 for all 60 Hz fluorescent reference ballasts, unless otherwise specified on a lamp data sheet. A rapid-start reference ballast when called for in this standa
38、rd includes 3.6 volts cathode heating, unless otherwise specified on the relevant lamp data sheets. 8. Product Drawings The drawings included in Part 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
39、families of lamps. The particular values vary with a family in accordance with the values on the relevant lamp data sheet. For self-supporting compact lamps, the general shape and size of a lamps maximum outline is specified in relation to the same drawings and the “Max. Lamp Outline“ dimensions on
40、a lamp data sheet. For the types of lamps covered in this standard, it has been industry practice to overlook minor bulb shape and construction differences in a maximum outline and to merely apply expanded values to the finished lamp dimension to specify the outline. C78.901-2014 Page 4 2014 Nationa
41、l Electrical Manufacturers Association 9. Applications of Lamps on More than One Type of Circuit Lamp data sheets in Part IV specify the intended circuit application. In some cases, a lamp may be used on more than one type of circuit. In such cases, the lamp data sheet will show the information for
42、all of the appropriate circuits. If a particular lamp class has been authorized by the lamp manufacturers for operation at high frequency conditions, the appropriate information will be supplied on the relevant lamp data sheet. 10 Lamp Physical and Dimensional Requirements 10.1 Bulb Specifications E
43、ach lamp data sheet in Part IV specifies the necessary bulb shape, tube diameter, and final lamp shape. Bulb shapes are defined in the bulb nomenclature standard, ANSI C78.79-2014. Due to the long established practice of referring to the diameter of fluorescent lamp bulbs in eighths-of-an-inch units
44、, this standard maintains that practice. For example, a “ diameter bulb is called a T4 bulb. Metric diameters, in millimeters, are shown in parentheses immediately following the customary designation. The basic bulb shape of some single-based fluorescent lamps may be additionally formed in the lamp
45、assembly process to acquire a final “lamp shape“. For example, some final shapes of lamps in this standard are referred to as twin or quad designs. There are not any requirements on finished lamp shape other than the specified lamp dimensions. 10.2 Base Specifications The required standardized base
46、type is specified on each lamp data sheet. Bases on finished lamps shall comply with the base standard, ANSI C81.61. Gauges for checking bases are included in ANSI C81.63. 10.3 Marking The following information shall be distinctly and durably marked on a lamp: - Mark of origin. This may take the for
47、m of a trademark, the manufacturers mark, or the name of the responsible vendor. - Nominal wattage, identified by a suffix “W.“ C78.901-2014 Page 5 2014 National Electrical Manufacturers Association 10.4 Lamp Dimensions Finished lamps shall comply with the “Finished Lamp“ dimensions specified on the
48、 relevant data sheet. Graphical definitions of the dimensional letter codes used on the data sheets are given in Part II. Where maximum lamp outline dimensions are specified, such outlines are the maximum limits of the space that may be occupied by any part of the bulb of a lamp. They are referenced
49、 to the base in a fixed position. Base-to-bulb misalignment is taken into consideration. 10.4.1 Base Alignment of U-Shaped Lamps with 2G13 Bases. All four pins (excluding flanges) of an assembled lamp shall pass simultaneously, without binding, through a single slot 0.120 inch (3.05mm) in width. 10.4.2 Base Rotation of Circular Lamps with G10q Bases. The base on a finished lamp shall be capable of being rotated, without difficulty, over at least an arc of 5 about the normal angle to the plane through the
