33、 60335-2-24:17 UL 60335-2-24 5PREFACEThis is the harmonized CSA Group and UL standard for particular requirements for refrigeratingappliances, ice-cream appliances and ice makers. It is the second edition of CAN/CSA-C22.2 No.60335-2-24, and the second edition of UL 60335-2-24. This edition of CAN/CS

34、A-C22.2 No. 60335-2-24supersedes the previous edition published on August 21, 2006 and replaces CSA C22.2 No. 63-93,Household Refrigerators and Freezers. This edition of UL 60335-2-24 supersedes the previous editionpublished on August 21, 2006.This harmonized standard is based on IEC Publication 603

35、35-2-24: Edition 7.1, Household and SimilarElectrical Appliances Safety Part 2-24: Particular Requirements for Refrigerating Appliances,Ice-Cream Appliances and Ice-Makers, issued May 2012. IEC 60335-2-24 is copyrighted by the IEC.This harmonized Standard was prepared by CSA Group and Underwriters L

36、aboratories Inc. (UL). Theefforts and support of the appliance manufacturing industry are gratefully acknowledged.This standard is considered suitable for use for conformity assessment within the stated scope of thestandard.This Standard was reviewed by the CSA Subcommittee on Household Appliances f

37、or Refrigeration underthe jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSAStrategic Steering Committee on Requirements for Electrical Safety, and has been formally approved bythe CSA Technical Committee. This Standard was also reviewed and approved by ULs S

38、tandardsTechnical Panel for Household Refrigerators and Freezers, STP 250.This Standard has been 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 AmericanNational Standard.Applicat

39、ion of StandardWhere 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 us

40、ers of the standard to judge its suitability for their particular purpose.CAN/CSA-C22.2 No. 60335-2-24 is to be used in conjunction with the first edition of CAN/CSA-C22.2 No.60335-1:11.

41、andard and CAN/CSA-C22.2 No. 60335-1:11. Requirements of this Part 2Standard, where stated, amend the requirements of CAN/CSA-C22.2 No. 60335-1:11. Where a particularsubclause of CAN/CSA-C22.2 No. 60335-1:11 is not mentioned in CAN/CSA-C22.2 No. 60335-2-24, theCAN/CSA-C22.2 No. 60335-1:11 subclause

42、applies.UL 60335-2-24 is to be used in conjunction with the fifth edition of UL 60335-1. The requirements forrefrigerating appliances, ice-cream appliances and ice makers are contained in this Part 2 Standard andUL 60335-1. Requirements of this Part 2 Standard, where stated, amend the requirements o

43、f UL 60335-1.Where a particular subclause of UL 60335-1 is not mentioned in UL 60335-2-24, the UL 60335-1subclause applies.APRIL 28, 2017CAN/CSA-C22.2 NO. 60335-2-24:17 UL 60335-2-246Level of HarmonizationThis standard adopts the IEC text with national differences. This standard is published as an e

44、quivalentstandard for CSA and UL.An equivalent 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 conflicts incodes and governmental regulations as well as those recognize

45、d as being in accordance withNAFTA Article 905, for example, because of fundamental climatic, geographical, technological,or infrastructural factors, scientific justification, or the level of protection that the countryconsiders appropriate.b) Presentation is word for word except for editorial chang

46、es that do not alter the technicalcontent of the standard. Examples of editorial changes include:1) different font sizes, figure sizes, and table sizes;2) minor variations in format, such as indentation and pagination;3) font appearance (including the use of italic or bold text or uppercase or lower

47、caseletters);4) the use of a symbol (e.g., A or %) rather than the word (Ampere or percent), or theword rather than the symbol;5) inclusion of inch-pound units for informational purposes;6) corrections of misprints or typographical errors;7) bilingual column headings or figure captions on a common t

48、able or figure in abilingual edition;8) change from first-angle to third-angle drawing;9) addition of a statement: “This is a first-angle drawing”; and10) substitution of a point (.) for a comma (,) as the decimal marker.All national differences from the IEC text are included in the CSA Group and UL

49、 versions of the standard.While the technical content is the same in each organizations version, the format and presentation maydiffer.Reasons for Differences From IECDifferences from the IEC are being added in order to address safety and regulatory situations present inthe US and Canada.APRIL 28, 2017 CAN/CSA-C22.2 NO. 60335-2-24:17 UL 603
