12、ANSI C81.61-2009 (R2014) 2009 National Electrical Manufacturers Association i 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
13、 approval have been met 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 direct
14、ly and materially affected 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 Standa
15、rd does not in any respect 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.
16、The American National 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 Amer

21、nal Electrical Manufacturers Association Foreword for American National Standard ANSI_C81.61-2009 (This foreword is not part of American National Standard ANSI C81.61-2009.) In 1990 and 1991 the American National Standards (ANS) for lamp bases, lampholders and gauges were split into three separate s
22、tandards to line up with the IEC format. ANSI C81.61, ANS for Electric Lamp Bases paralleled 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 C8
23、1.64 Guidelines for Electrical Lamp Bases, Lampholders and Gauges was published to 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 m
24、any more (if not most) ANSI base standard sheets are IEC sheets adopted as ANSI standards. 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 base
25、s used mainly in North America or not harmonized with IEC are found in Part II. Part 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
26、 first versus third angle projection and related standards.

33、eneral information Two types of base standard 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 servi
34、ce including common Edison screw base; red 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 s
35、tandard sheet is included. These standard sheets are identified in Table 1- ANSI and IEC Lamp Base Standard Sheets under the column heading “ANSI C81.61“. These Standard Sheets are found in Part I. ANSI C81.61-2009 (R2014) 2 2009 National Electrical Manufacturers Association Certain standard sheets
36、from IEC standard 60061-1 Lamp caps and holders together with gauges 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
37、(Caps). The standard sheets for these bases are not included, but are identified in Table I-ANSI and IEC Lamp Base Standard Sheets under the column heading “IEC 60061-1“. If there are any United States deviations from these standard sheets, the sheet number is marked with a footnote and the deviatio
38、ns are found in Part III.

39、he 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 American term “Base“ i
40、s 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 conjunction with ANSI_ANSLG
