37、 (EV) Supply Circuits: Particular Requirements for Protection Devices for Use in Charging Systems. It is the Second edition of NMX-J-6682-ANCE, the First edition of CAN/CSA-C22.2 No. 281.2, and the Second edition of UL 22312. This harmonized standard has been jointly revised on August 26, 2016. For
38、this purpose, CSA Group and UL are issuing revision pages dated August 26, 2016, and ANCE is issuing a new edition dated August 26, 2016. This harmonized standard was prepared by the Association of Standardization and Certication (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The effort
39、s and support of the Technical Harmonization Working Group for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits are gratefully acknowledged. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. The present Mexican Stand
40、ard was reviewed and approved by the Comit de Normalizacin de la Asociacin de Normalizacin y Certicacin, A.C., CONANCE. This standard was reviewed by the CSA Subcommittee on Electric Vehicle Personal Protection Systems for Supply Circuits, under the jurisdiction of the CSA Technical Committee on Ind
41、ustrial 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 as a National Standard of Canada by the Standards Council of Canada (SCC). This standard has been approved b
42、y the American National Standards Institute (ANSI) as an American National Standard. Application of Standard Where reference is made to a specic number of specimens to be tested, the specied number is to be considered a minimum quantity. Note: Although the intended primary application of this standa
43、rd is stated in its scope, 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 considered equivalent to, an IEC standard. Th
44、is standard is published 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 a
45、s being in accordance with 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. AU

47、 vehicle supply circuits for use in accordance with the electrical installation codes of Canada, Mexico, and the United States. At present there is no IEC standard for these products for use in accordance with these codes. Therefore, this standard does not employ any IEC standard for base requiremen
48、ts. 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. If more than one interpret
49、ation 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.
