It is the Second ed
41、ition of NMX-J-677-ANCE, the Second edition of CSA C22.2 No. 280, and the Second edition of UL 2594. This edition of NMX-J-677-ANCE supersedes the previous edition published on February 22, 2013. This edition of CSA-C22.2 No. 280 supersedes the previous edition published on February 22, 2013. This e
42、dition of UL 2594 supersedes the previous edition published on February 22, 2013. This harmonized standard was prepared by the Association of Standardization and Certication (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Working Gro
43、up for Electric Vehicle Supply Equipment 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 reviewed and approved by the Comit de Normalizacin de la Asociacin de Normalizacin y
44、Certicacin, A.C., CONANCE. This standard was reviewed by the CSA Subcommittee on Electric Vehicle Supply Equipment, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally appro
45、ved by the CSA Technical Committee. This standard has been approved by 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 qua
46、ntity. 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 suitability for their particular purpose. Level of harmonization This standard uses the IEC format but
47、is not based on, nor is 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 substantially the same in technical content, except as follows: Technical national differences are allowed
48、 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 infrastructural factors, scientic justication, or the level of protection that the country considers approp
49、riate. Presentation is word for word except for editorial changes.
