It is the fifthedition of NMX-J-436-ANCE, the four

25、teenth edition of CSA-C22.2 No. 49, and the nineteenth edition ofUL 62. This edition of CSA C22.2 No. 49 supersedes the previous edition(s) published in 2010, 2006,1998, 1992, 1989, 1988, 1981, 1973, 1962, 1960, 1956, 1941, and 1937. This edition of UL 62supersedes the previous edition published in

26、2010.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 Subcommittee, Flex Cords, THSC 20, of the Council on the Harmonization ofElectrotechnica

27、l 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 thestandard.The present Mexican standard was developed by the CT 20 Conductores from the Comite deNormalizacion de la Asoc

28、iacion de Normalizacion y Certificacion, A.C., CONANCE, with the collaborationof the wire and cables manufacturers and users.This standard was reviewed by the CSA Integrated Committee on Flexible Cords/Equipment andAppliance Wires and Cables, under the jurisdiction of the CSA Technical Committee on

29、Wiring Productsand the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formallyapproved by the CSA Technical Committee.This standard has been approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Application of StandardWhere

30、 reference is made to a specific number of samples 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 is important to note thatit remains the responsibility of the users of the standard

31、to judge its suitability for their particular purpose.Level of HarmonizationThis standard uses the IEC format but is not based on, nor is it to be considered equivalent to, an IECstandard. This standard is published as an equivalent standard for ANCE, CSA Group, and UL.An equivalent standard is a st

32、andard that is substantially the same in technical 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, technol

33、ogical, or infrastructural factors, scientific justification, or the level of protection thatthe country considers appropriate. Presentation is word for word except for editorial changes.MARCH 14, 2014NMX-J-436-ANCE-2014 CSA C22.2 NO. 4914 UL 624Reasons for Differences From IECThis standard provides

34、 requirements for insulated cords and cables in accordance with the codes ofCanada, Mexico, and the United States. At present there is no IEC standard for cords and cables for usein accordance with these codes. Therefore, this standard does not employ any IEC standard for baserequirements.Interpreta

35、tionsThe 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. If more than one interpretation of the lite

36、ral 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.ANCE Effective DateThe effective date for ANCE will be announced through the Diario Oficial de Ia Federacin (OfficialGazette) and is i

37、ndicated on the cover page.CSA Group Effective DateThe effective date for CSA Group will be announced through CSA Informs or CSA Group CertificationNotice.UL Effective DateAs of March 14, 2016, all products Listed or Recognized by UL must comply with the requirements in thisstandard.Between March 14

38、, 2014, and March 14, 2016, new product submittals to UL may be evaluated under allrequirements in this standard or, if requested in writing, evaluated under presently effective requirementsonly.A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSIappro

39、ved standard.MARCH 14, 2014 NMX-J-436-ANCE-2014 CSA C22.2 NO. 4914 UL 62 51 Scope1.1 GeneralThis standard specifies the requirements for flexible cords, elevator cables, electric vehicle cables, electricvehicle cables, and hoistway cables rated 600 V maximum and intended for use in accordance with C
