32、 for Safety for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits: Particular Requirements for Protection Devices for Use in Charging Systems. It is the First edition of NMX-J-668/2-ANCE, the First edition of CSA C22.2 No. 281.2, and the Second edition of UL 22312. This edition

33、of UL 22312 supersedes the previous edition published in 2002. 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 Group for Personnel Pr

34、otection 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 Standard was reviewed and approved by the Comit de Normalizacin de la Asociacin

35、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 Industrial Products and the CSA Strategic Steering Committee on Requirements f

36、or 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 is made to a specic number of specimens to be tested, the specied number is to be

37、 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 suitability for their particular purpose. Level of harmonization This standard

38、 uses the IEC format but 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 nationa

39、l 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 infrastructural factors, scientic justication, or the level of protection that the

40、 country considers appropriate. Presentation is word for word except for editorial changes. Reasons for differences from IEC This standard provides particular requirements for personnel protection systems for electric vehicle supply circuits for use in accordance with the electrical installation cod

41、es 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 requirements. SEPTEMBER 7, 2012 NMX-J-668/2-ANCE CSA C22.2 NO. 281.212 UL 2231-2 5UL COPYRIGH
