31、NCE CAN/CSA-C22.2 NO. 281.212 UL 2231-2 5PREFACEThis is the harmonized ANCE, CSA Group, and UL Standard for Safety for Personnel Protection Systemsfor Electric Vehicle (EV) Supply Circuits: Particular Requirements for Protection Devices for Use inCharging Systems. It is the Second edition of NMX-J-6

32、682-ANCE, the First edition of CAN/CSA-C22.2No. 281.2, and the Second edition of UL 22312. This harmonized standard has been jointly revised onAugust 26, 2016. For 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.

33、This harmonized standard was prepared by the Association of Standardization and Certification (ANCE),CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the TechnicalHarmonization Working Group for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuitsare g

34、ratefully acknowledged.This Standard is considered suitable for use for conformity assessment within the stated scope of theStandard.The present Mexican Standard was reviewed and approved by the Comit de Normalizacin de laAsociacin de Normalizacin y Certificacin, A.C., CONANCE.This standard was revi

35、ewed by the CSA Subcommittee on Electric Vehicle Personal Protection Systemsfor Supply Circuits, under the jurisdiction of the CSA Technical Committee on Industrial Products and theCSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formallyapproved by the CSA Techni

36、cal Committee.This standard has been approved as a National Standard of Canada by the Standards Council of Canada(SCC).This standard has been approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Application of StandardWhere reference is made to a specific numb

37、er of specimens to be tested, the specified number is to beconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated in its scope, it isimportant to note that it remains the responsibility of the users of the standard to judge itssuitability for their p

38、articular purpose.Level of harmonizationThis standard 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 tech

39、nical content, except as follows:Technical national differences are allowed for codes and governmental regulations as well as thoserecognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic,geographical, technological, or infrastructural factors, scientifi

Presentation is word for word except for editorial changes.AUGUST 26, 2016NMX-J-668-2-ANCE CAN/CSA-C22.2 NO. 281.212 UL 2231-26Reasons for differences from IECThis standard provides particular requirements for personn

41、el protection systems for electric vehicle supplycircuits for use in accordance with the electrical installation codes of Canada, Mexico, and the UnitedStates. At present there is no IEC standard for these products for use in accordance with these codes.Therefore, this standard does not employ any I

42、EC standard for base requirements.InterpretationsThe interpretation by the standards development organization of an identical or equivalent standard isbased on the literal text to determine compliance with the standard in accordance with the proceduralrules of the standards development organization.

43、 If more than one interpretation of the literal text has beenidentified, a revision is to be proposed as soon as possible to each of the standards developmentorganizations to more accurately reflect the intent.AUGUST 26, 2016 NMX-J-668-2-ANCE CAN/CSA-C22.2 NO. 281.212 UL 2231-2 6APersonnel Protectio

45、nless modified by this Standard.2 General2.1 This Part contains the construction and performance requirements that are applied to a device that isintended to become an integral part of an overall device or charging system.2.2 Annex A, Ref. No. 1 contains an outline of the features required to provid

46、e protection based onvoltage and grounding or isolation of the system or part of the system under consideration.3 Components3.1 Except as indicated in 3.2, a component of a product covered by this standard shall comply with therequirements for that component.3.2 A component is not required to comply

47、 with a specific requirement that:a) Involves a feature or characteristic not required in the application of the component in theproduct covered by this standard, orb) Is superseded by a requirement in this standard.3.3 A component shall be used in accordance with its rating established for the inte
