12、ciation 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 standards developer. An American Nationa

13、l 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 interests. Substantial agreement means much

14、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 anyone, whether s/he has approved t

15、he 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 Institute, Inc., does not develop stand

16、ards 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, Inc. Requests for interpretations sh

The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdra

21、rt of American National Standard C81.62.) In 1990 and 1991 the American National Standards (ANS) for lamp bases, lampholders and gauges were split into three separate standards to line up with the IEC format. ANSI C81.61, ANS for Electric Lamp Bases paralleled IEC 60061-1; ANSI C81.62, ANS for Lamph

22、olders 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 to parallel IEC 60061-4 in 1993. In 1996, the first

23、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 standards. In 2003, a revision and consolidation of

24、ANSI C81.62 was issued to include, first, a reference to all IEC lampholder standard sheets adopted as ANSI standards. Second, standard sheets for a small number of lampholders used mainly in North America or not harmonized with IEC were included in Part II. Part III contained any United States devi

25、ations to the IEC standard sheets, which had been adopted as Nationally Acknowledged International Standards as published in IEC 60061-2. Part IV contained an informative annex on first versus third angle projection and related standards. ANSI C81.62-2017 Page iii 2017 National Electrical Manufactur

33、 Two types of lampholder standard sheets are identified in this standard, and both are listed in Table 1, ANSI and IEC Lampholder Standard Sheets. All lampholder types are listed in color to indicate their applications: Blue for automotive and miniature; green for general lighting service including

34、common Edison screw lampholders; red for fluorescent; and black for miscellaneous. For some lampholders either no international standard exists or the international standard is not acceptable at this time. For such lampholders an ANSI standard sheet is included. These standard sheets are identified

35、in Table 1ANSI and IEC Lampholder Standard Sheets under the column heading “ANSI C81.62“. These Standard Sheets are found in Part II. ANSI C81.62-2017 Page 2 2017 National Electrical Manufacturers Association Certain standard sheets from IEC standard 60061-1 Lamp caps and holders together with gauge

36、s for the control of the interchangeability and safety, Part 2: Lampholders, and its supplements, have been adopted as Nationally Acknowledged International Standards and constitute part of the American National Standard for Lampholders. The standard sheets for these lampholders are not included, bu

37、t are identified in Table IANSI and IEC Lampholder Standard Sheets under the column heading “IEC 60061-2“. If there are any United States deviations from these IEC standard sheets; the sheet number is marked with a footnote and the deviations are found in Part III. These IEC standards are available

39、 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. Annex A explains the difference between the two systems. In addition, the common American term “Base“ is inter

40、nationally 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 C81.61, Bases

41、 (Caps) for Electric Lamps; ANSI C81.63, 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 1: Caps, and Part 3: Gauges. In addition the safety requirements for Edison screw lampholders

42、are found in UL 496, Edison-Base Lampholders and the safety requirements for fluorescent lamp bases and starter holders are found in UL 542, Lampholders, Starters, and Starter Holders for Fluorescent Lamps.
