29、6A-486B 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the harmonized ANCE, CSA Group, and UL standard for Wire Connectors. It is the third edition of NMX-J-543-ANCE, the fth edition of CSA C22.2 No. 65, and the second edit
30、ion of UL 486A-486B. This edition of NMX-J-543-ANCE cancels the previous edition published in 2008. This edition of CSA C22.2 No. 65 supersedes the previous edition published in 2003. This edition of UL 486A-486B supersedes the previous edition published in 2003. This harmonized standard was prepare
31、d by the Association of Standardization and Certication (ANCE), the CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Connectors, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (C
32、ANENA), are gratefully acknowledged. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This standard was reviewed by the CSA Subcommittee on Wiring Devices for Household and General Use, under the jurisdiction of the CSA Technical Committ
33、ee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Where reference i
34、s made to a specic number of samples to be tested, the specied number is to be considered a minimum quantity. Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its
35、suitability for their particular purpose. Level of harmonization This standard uses the IEC format but is not based on, nor is it considered equivalent to, an IEC standard. This standard is published as an equivalent standard for ANCE, CSA Group, and UL. An equivalent standard is a standard that is
36、substantially the same in technical content, except as follows: Technical national differences are allowed for codes and governmental regulations as well as those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic, geographical, technological, or i
37、nfrastructural factors, scientic justication, or the level of protection that the country considers appropriate. Presentation is word for word except for editorial changes. Reasons for differences from IEC The Technical Harmonization Committee identied several IEC standards that address electrical w
38、ire connectors included in the scope of this standard. The IEC standards for electrical wire connectors are recognized as being generally system specic, containing the requirements for the relevant wire connectors and cables in many discrete IEC standards.

39、O. 65-13 UL 486A-486B 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL The THC determined the safe use of electrical wire connectors is dependent on the design and performance of the wire connectors in relation to the North American Electric
40、al Codes with which they are intended to be installed. The THC agreed such future investigation will be facilitated by the harmonization of the North American Electrical Codes for wire connectors with IEC installation practices. Interpretations The interpretation by the standards development organiz
41、ation of an identical or equivalent standard is based on the literal text to determine compliance with the standard in accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identied, a revision is to be proposed a
42、s soon as possible to each of the standards development organizations to more accurately reect the intent. ANCE effective date The effective date for ANCE will be announced through the Diario Ocial de la Federacin (Official Gazette) and is indicated on the cover page. CSA Group effective date The ef
43、fective date for CSA Group will be announced through CSA Informs or a CSA Group certication notice. UL effective date As of February 28, 2014, all products Listed or Recognized by UL must comply with the requirements in this standard. A UL effective date is one established by Underwriters Laboratori
44、es Inc. and is not part of the ANSI approved standard.
