31、 is the harmonized CSA Group and UL standard for particular requirements for motor-compressors. It is the second edition of CAN/CSA-C22.2 No. 60335-2-34, and the sixth edition of UL 60335-2-34. This edition of CAN/CSA-C22.2 No. 60335-2-34 supersedes the previous edition published on March 22, 2013.

32、This edition of UL 60335-2-34 supersedes the previous edition published on March 22, 2013. This harmonized standard is based on IEC Publication 60335-2-34: Edition 5.2, Household and Similar Electrical Appliances Safety Part 2-34: Particular Requirements for Motor-Compressors, issued November 2016.

33、IEC 60335-2-34 is copyrighted by the IEC. This harmonized Standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the motor-compressor manufacturing industry are gratefully acknowledged. This standard is considered suitable for use for conformity assess

34、ment within the stated scope of the standard. 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 Strategic Steering Committee on Requirements for Electrica

35、l Safety, and has been formally approved by the CSA Technical Committee. This Standard was also reviewed and approved by ULs Standards Technical Panel for Heating and Cooling Equipment Particular Requirements for Motor-Compressors, STP 60335-2-34. This Standard has been approved as a National Standa

36、rd 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. Application of Standard Where reference is made to a specic number of samples to be tested, the specied number is to be considered

37、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 users of the standard to judge its suitability for their particular purpose. CAN/CSA-C22.2 No. 60335-2-34 is to be used in co

38、njunction with the second edition of CAN/CSA-C22.2 No. 60335-1:16. The requirements for motor-compressors 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 partic

39、ular subclause of CAN/CSA-C22.2 No. 60335-1:16 is not mentioned in CAN/CSA-C22.2 No. 60335-2-34, the CAN/CSA-C22.2 No. 60335-1:16 subclause applies. UL 60335-2-34 is to be used in conjunction with the sixth edition of UL 60335-1. The requirements for motor-compressors are contained in this Part 2 St

40、andard and UL 60335-1. Requirements of this Part 2 Standard, where stated, amend the requirements of UL 60335-1. Where a particular subclause of UL 60335-1 is not mentioned in UL 60335-2-34, the UL 60335-1 subclause applies. NOVEMBER 3, 2017 CAN/CSA-C22.2 NO. 60335-2-34:17 UL 60335-2-34 6UL COPYRIGH

41、TED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Level of Harmonization This standard adopts the IEC text with national differences. This standard is published as an equivalent standard for CSA and UL. An equivalent standard is a standard that is substa

42、ntially 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 905, for example, because of fundamental

43、 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 the standard. Examples of editorial ch

44、anges 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); 4) the use of a symbol (e.g., A or %) rather than the word (Ampere

45、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 gure in a bilingual edition; 8) change from rst-angle to third-angle d

46、rawing; 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 of the standard. While the technical content is the same in each orga

47、nizations 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.
