This edition of UL 60335-234 supersedes the previous edition(s) published in March, 2004. This Standard is based on the Standard for Safety
32、 of Household and Similar Electrical Appliances, Part 2-34: Particular Requirements for Motor-Compressors, IEC Publication 60335-234, edition 4.2. In Canada, for general information on the Standards of the Canadian Electrical Code, Part II, see the preface of CAN/CSA-C22.2 No. 0. This harmonized sta
33、ndard was prepared by the Association of Standardization and Certication (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of Industry Associations Cmara Nacional de Manufacturas Elctricas (CANAME), the Heating, Refrigeration and Air Conditioning Institute of Canada
34、 (HRAI), the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), and the Association of Home Appliance Manufacturers (AHAM), and of the Technical Harmonization Sub-Committee (THSC 61D TC1) of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CA
35、NENA), 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 developed by the CT 61 from the Comite de Normalizacion de la Asociacion de Normalizacion y Certicacion, A.C., CONANCE
36、with the collaboration of the heating, refrigeration and air conditioning manufacturers and users. This standard was reviewed by the CSA Subcommittee on Household Appliances for Refrigeration, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strat
37、egic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved by the Standards Council of Canada (SCC) as a National Standard of Canada. This Standard has been approved by the American National Standards
38、Institute (ANSI) as an American National 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 r
39、emains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of harmonization This standard adopts the IEC text with national differences. This standard is published as an equivalent standard for ANCE, CSA Group, and UL. An equivalent standard i
40、s 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 MARCH 22, 2013 NMX-J-521/2-34-ANCE CAN/CSA-C22.2 NO. 6

While the technical content is the same in each organizations version, the format and presentation may d
43、iffer. It is the intent and objective of the US, Canadian, and Mexican SDOs and associated Industries to avoid the use of single country deviations to the greatest extent possible and practical. Single country deviations should only be used as a last resort when all other options have been explored.
44、 Further this includes a commitment to review and reconsider any and all single country revisions at each revision cycle with the intent of nding solutions to remove the single county deviation in the spirit of tri-national harmonization. A list of work item requests will be recorded between revisio
45、n cycles and by default removal of all single country deviations will be on the list for the next revision cycle. Reasons for differences from IEC National Differences from the IEC are being added in order to address regulatory and safety situations present in Canada, Mexico, and the US. Interpretat
46、ions The interpretation by the standards development organization 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 literal interpretation h
47、as been identied, a revision is to be proposed 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
48、 the cover page. CSA Group Effective Date The effective date for CSA Group will be announced through CSA Informs or a CSA Group certication notice. UL Effective Date As of March 22, 2013, all products Listed or Recognized by UL must comply with the requirements in this standard. A UL effective date
