27、GHTED 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 edition of UL 486A-486
28、B. This harmonized standard has been jointly revised on January 20, 2016. This harmonized standard was prepared 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 C
29、onnectors, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. The present Mexican standard was develope
30、d by the SC 20D - Conectadores part of the CT 20 - Conductores from the Comite de Normalizacion de la Asociacion de Normalizacion y Certicacion, A.C., CONANCE, with the collaboration of the connectors manufacturers and users. This standard was reviewed by the CSA Subcommittee on Wiring Devices for H
31、ousehold and General Use, under the jurisdiction of the CSA Technical Committee 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 S
32、tandards Institute (ANSI) as an American National Standard. Application of Standard Where reference is 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,
33、it is important to note that it remains the responsibility of the users of the standard to judge its 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
34、 as an equivalent standard for ANCE, CSA Group, and UL. An equivalent standard is a standard that is 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 wi
35、th NAFTA Article 905, for example, because of fundamental climatic, geographical, technological, or infrastructural 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 fr
36、om IEC The Technical Harmonization Committee identied several IEC standards that address electrical wire 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 w
37、ire connectors and cables in many discrete IEC standards. JANUARY 20, 2016 NMX-J-543-ANCE CSA-C22.2 NO. 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 depe
38、ndent on the design and performance of the wire connectors in relation to the North American Electrical 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 wit
39、h IEC installation practices. Interpretations The interpretation by the standards development organization 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.
40、If more than one interpretation of the literal text has been identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent.
