35、 and UL standard for exible cords and cables. It is the sixth edition of NMX-J-436-ANCE, the fteenth edition of CAN/CSA-C22.2 No. 49, and the twentieth edition of UL 62. This edition of CAN/CSA C22.2 No. 49 supersedes the previous edition(s) published in 2014, 2010, 2006, 1998, 1992, 1989, 1988, 198
36、1, 1973, 1962, 1960, 1956, 1941, and 1937. This edition of UL 62 supersedes the previous edition published in 2014. 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 T
37、echnical Harmonization Subcommittee, Flex Cords, THSC 20, 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 within the stated scope of the stand
38、ard. 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 wire and cables manufacturers and users. This standard was reviewed by the CSA Integrated Committee
39、on Flexible Cords/Equipment and Appliance 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 has been d
40、eveloped in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Applicatio
41、n 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 application of this standard is stated in its scope, it is important to note that it remains the responsibility of the user
42、s 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 to be considered equivalent to, an IEC standard. This standard is published as an equivalent standard for ANCE, CSA Group, and UL. An equiv
43、alent standard is a standard that is substantially the same in technical content, except as follows: Technical national 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 climat
44、ic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriate. Presentation is word for word except for editorial changes. JULY 6, 2018 NMX-J-436-ANCE-2018 CAN/CSA C22.2 NO. 49-18 UL 62 4UL COPYRIGHTED MATERIAL NO
45、T AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Reasons for Differences From IEC This standard provides requirements for insulated cords and cables in accordance with the codes of Canada, Mexico, and the United States. At present there is no IEC standard for cords an
46、d cables for use in accordance with these codes. Therefore, this standard does not employ any IEC standard for base requirements. Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine compliance w
47、ith the standard in accordance with the procedural rulesofthestandardsdevelopmentorganization.Ifmorethanoneinterpretationoftheliteraltexthasbeen identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent.
