35、monized ANCE, CSA Group, and UL standard for Thermoset-Insulated Wires and Cables. It is the Fifth edition of NMX-J-451-ANCE, the Tenth edition of CSA C22.2 No. 38, and the Eighteenth edition of UL 44. This edition of NMX-J-451-ANCE supersedes the previous edition published in 2010. This edition of

36、CSA C22.2 No. 38 supersedes the previous edition published in 2010. This edition of UL 44 supersedes the previous edition published in 2010. This harmonized standard was prepared by the Association of Standardization and Certication, (ANCE), CSA Group and Underwriters Laboratories Inc. (UL). The eff

37、orts and support of the Technical Harmonization Committee for Electrical Wires and Cables, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This Standard is considered suitable for use for conformity assessment wi

38、thin the stated scope of the Standard. The present Mexican Standard was developed by the CT 20 Conductores from the Comite de Normalizacion de la Asociacion de Normalizacion y Certicacion, A.C., CONANCE, with the collaboration of the SC 20B Conductores para Baja Tensin. This standard was reviewed by

39、 the CSA Integrated Committee on Fixed Installation Wires and Cables, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard

40、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 samples to be tested, the specied number is to be considered a minimum quantity. Note: Although the intended primary applicati

41、on 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 is not based on, nor is it considered equivalent to,

42、 an IEC standard. This standard provides requirements for insulated wires and cables for use in accordance with the electrical installation codes of Canada, Mexico, and the United States. At present there is no IEC standard for wires and cables for use in accordance with these codes. Therefore, this

43、 standard does not employ any IEC standard for base requirements. 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

44、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 appropr

45、iate. Presentation is word for word except for editorial changes.

46、rganization 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 interpretation of the literal text has been identied, a revision is to be prop

47、osed as soon as possible to each of the standards development organizations to more accurately reect the intent. ANCE Effective Date The effective date for ANCE will be announced through the Diario Ocial de la Federacin (Official Gazette) and is indicated on the cover page. CSA Group Effective Date

48、The effective date for CSA Group will be announced through a CSA Informs or CSA Group Certication Notice. UL Effective Date As of March 28, 2014 all products Listed or Recognized by UL must comply with the requirements in this standard. A UL effective date is one established by Underwriters Laborato
