12、ational 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 met by the sta

13、ndards 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 affected interes

14、ts. 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 respect preclude

15、 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 Standards Ins

16、titute, 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 Standards Institute,

17、Inc. Requests for interpretations should be addressed to the Committee Secretariat referred to on the 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 CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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 that action be taken p

18、eriodically to reaffirm, revise, or withdraw this standard.

21、tion Foreword (This foreword is not part of American National Standard ANSI C81.61) In 1990 and 1991 the American National Standards (ANS) for lamp bases, lampholders and gauges were split into three separate standards to correspond with the IEC format. ANSI C81.61, ANS for Electric Lamp Bases, para

22、lleled IEC 60061-1; ANSI C81.62, ANS for Lampholders for Electric Lamps, paralleled IEC 60061-2; and ANSI C81.63, Gauges for Electric Lamp Bases and Lampholders, paralleled IEC 60061-3. Also a fourth standard, ANSI C81.64, Guidelines for Electrical Lamp Bases, Lampholders and Gauges, was published t

23、o parallel IEC 60061-4 in 1993. In 1996 the first IEC data sheets were adopted “as is” as Nationally Acknowledged International Standards and published as Supplement g to the existing C81.61, 62 and 63 standards. Now many more (if not most) ANSI base standard sheets are IEC sheets adopted as ANSI st

24、andards. In 2003 a revision and consolidation of ANSI C81.61 was issued to include, first, a reference to all IEC base (cap) standard sheets adopted as ANSI standards. Second, standard sheets for a small number of bases used mainly in North America or not harmonized with IEC are found in Part II. Pa

25、rt III contained any United States deviations to the IEC standard sheets, which had been adopted as Nationally Acknowledged International Standards as published in IEC 60061-1. Part IV contained an informative annex on first versus third angle projection and related standards. ANSI C81.61-2016 Page

29、ts. 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 for identifying any or all such patent rights. 2 Normative References The fo

33、rd sheets are identified in this standard, and both are listed in Table 1, ANSI and IEC Lamp Base Standard Sheets. All base types are listed in color to indicate their typical applications: blue for automotive and miniature; green for general lighting service, including common Edison screw base; red

34、 for fluorescent; and black for miscellaneous, including specialty, photo, projection, and studio stage applications. For some bases, either no international standard exists or the international standard is not acceptable at this time. For such bases an ANSI standard sheet is included. These standar

35、d sheets are identified in Table 1, “ANSI and IEC Lamp Base Standard Sheets” under the column heading “ANSI C81.61-2016.” These standard sheets are found in Part I. Certain standard sheets from International Electrotechnical Commission (IEC) standard 60061-1, Lamp caps and holders together with gaug

36、es for the control of the interchangeability and safety Part 1: Lamp caps, and its supplements, have been adopted as Nationally Acknowledged International Standards and constitute part of the American National Standard for Lamp Bases (Caps). The standard sheets for these bases are not included but a

37、re identified in Table I, “ANSI and IEC Lamp Base Standard Sheets,” under the column heading “IEC 60061-1.” If there are any U.S. deviations from these standard sheets, the sheet number is marked with a footnote and the deviations are found in Part III.

The drawings on the internationally standardized (IEC) sheets are in first angle projection rather than the third angle commonly used in the North American (ANSI)approved standard sheets. Part IV, Annex A explains the difference between the two systems. In addition, the common

40、American term “Base” is internationally known as “Cap.” Internationally, the decimal point (.) is not used in dimensions, rather a comma (,) separates a decimal number, e.g., 4,5 rather than 4.5. However, in the designation of a fit, the decimal point is used, e.g., GY6.35. This standard is used in

41、conjunction with ANSI C81.62-2009 (R2014), Lampholders for Electric Lamps; ANSI C81.63-2009 (R2014), Gauges for Bases and Lampholders for Electric Lamps; and IEC 60061, Lamp caps and holders together with gauges for the control of interchangeability and safety, Part 2: Lampholders, and Part 3: Gauge
