32、SA Group and UL standard for particular requirements for Commercial Refrigerating Appliances with an Incorporated or Remote Refrigerant Unit or Compressor. It is the rst edition of CAN/CSA-C22.2 No. 60335-2-89, and the rst edition of UL 60335-2-89. This harmonized standard is based on IEC Publicatio

33、n 60335-2-89: Edition 2.1, Household and Similar Electrical Appliances Safety Part 2-89: Particular Requirements for Commercial Refrigerating Appliances with an Incorporated or Remote Refrigerant Unit or Compressor, issued July 2012. IEC 60335-2-89 is copyrighted by the IEC. This harmonized Standard

34、 was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the commercial refrigerating appliance manufacturing industry are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. Th

35、is 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 Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the

36、CSA Technical Committee. This Standard was also reviewed and approved by ULs Standards Technical Panel for Commercial Refrigerators and Freezers, STP 471. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada (SCC) and approved by the American National S

37、tandards Institute (ANSI) for publication 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 application of this standard is state

38、d 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.

39、rcial Refrigerating Appliances with an Incorporated or Remote Refrigerant Unit or Compressor are contained in this Part 2 Standard and CAN/CSA-C22.2 No. 60335-1:16. Requirements of this Part 2 Standard, where stated, amend the requirements of CAN/CSA-C22.2 No. 60335-1:16. Where a particular subclaus

40、e of CAN/CSA-C22.2 No. 60335-1:16 is not mentioned in CAN/CSA-C22.2 No. 60335-2-89, the CAN/CSA-C22.2 No. 60335-1:16 subclause applies. UL 60335-2-89 is to be used in conjunction with the sixth edition of UL 60335-1. The requirements for Commercial Refrigerating Appliances with an Incorporated or Re

41、mote Refrigerant Unit or Compressor are contained in this Part 2 Standard and UL 60335-1. Requirements of this Part 2 Standard, where stated, amend the requirements of UL 60335-1.

This standard is published as an equivalent standar

43、d 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 conicts in codes and governmental regulations as well as those recognized as being in a

44、ccordance 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 appropriate. b) Presentation is word for word except for editorial changes that do not

45、alter the technical content of the standard. Examples of editorial changes include: 1) different font sizes, gure 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 lowercase letters)

46、; 4) the use of a symbol (e.g., A or %) rather than the word (Ampere or percent), or the word 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 gure captions on a common table or g

47、ure in a bilingual edition; 8) change from rst-angle to third-angle drawing; 9) addition of a statement: “This is a rst-angle drawing”; and 10) 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 versions

48、of the standard. While the technical content is the same in each organizations version, the format and presentation may differ. Reasons for Differences From IEC Differences from the IEC are being added in order to address safety and regulatory situations present in the US and Canada. SEPTEMBER 29, 2
