36、ATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the common ANCE, CSA, and UL standard for particular requirements for refrigerating appliances, ice-cream appliances and ice makers. It is the third edition of NMX-J-521/2-24-ANCE, the rst edit

37、ion of CAN/CSA C22.2 No. 60335-2-24, and the rst edition of UL 60335-2-24. It was developed in part from the fourth edition of Household Refrigerators and Freezers, CSA C22.2 No. 63-93, the tenth edition of the Standard for Household Refrigerators and Freezers, UL 250, and the latest edition of Safe

38、ty of Household and Similar Electrical Appliances Part 2-24: Particular Requirements for Refrigerators, Freezers and Ice-makers, NMX-J-521/2-24-ANCE. This ANCE edition supersedes the edition published in 2001. This CSA edition supersedes CAN/CSA-E335-2-24-94, Safety of Household and Similar Electric

39、al Appliances Part 2: Particular Requirements for Refrigerators, Food-Freezers and Ice-makers. This Standard is based on the sixth edition of the Standard for Safety of Household and Similar Electrical Appliances, Part 2: Particular Requirements for Refrigerating Appliances, Ice-Cream Appliances and

40、 Ice Makers, IEC 60335-2-24. At the time of this publication, IEC 60335-2-24:2002 (Edition 6) is available from IEC in English only. CSA will publish the French version when it becomes available from IEC. This common Standard was prepared by the Association of Standardization and Certication (ANCE),

41、 the Canadian Standards Association (CSA), and Underwriters Laboratories Inc. (UL). The efforts and support of the appliance manufacturing industry are gratefully acknowledged. The present Mexican Standard was developed by the Mexican TC 61 “Safety of household and similar electrical appliances” bel

42、onging to CONANCE (ANCEs Standardization Committee) with the contribution of household appliances manufacturers and users. This Standard was reviewed by the CSA Subcommittee on Household Refrigerators and Freezers, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Prod

43、ucts and the CSA/Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This Standard was also reviewed and approved by ULs Standards Technical Panel for Household Refrigerators and Freezers, STP 250. This Standard has been

44、approved as a National Standard of Canada by the Standards Council of Canada (SCC) and approved by the American National Standards Institute (ANSI) for publication as an American National Standard. NOTE Although the intended primary application of this Standard is stated in its Scope, it is importan

45、t 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 adopts the IEC text with national differences. This standard is published as an equivalent standard for ANCE, CSA and UL. An equivalen

46、t standard is a standard that is substantially the same in technical content, except as follows: a) Technical national differences are allowed for national differences resulting from conicts in codes and governmental regulations as well as those recognized as being in accordance with NAFTA Article 9

47、05, for example, because of fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriate. b) Presentation is word for word except for editorial changes that do not alter the technical content of

48、 the standard. Examples of editorial changes include: AUGUST 21, 2006 NMX-J-521/2-24-ANCE-2006 CAN/CSA C22.2 NO. 60335-2-24-06 UL 60335-2-24 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 1) different font sizes, gure sizes, and table size
