38、R REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the harmonized CSA Group and UL standard for general requirements for safety of household and similar appliances. It is the second edition of CAN/CSA C22.2 No. 60335-1, and the sixth edition of UL 60335-1. This edition of CAN/

39、CSA-C22.2 No. 60335-1 coexists with the previous edition(s) published on October 31, 2011. This edition of UL 60335-1 supersedes the previous edition(s) published on October, 31, 2011. This harmonized standard is based on IEC Publication 60335-1: edition 5.1 Standard for Safety of Household and Simi

40、lar Appliances, Part 1: General Requirements issued April, 2014, including corrigendum 1 (2010), corrigendum 2 (2011) and its amendment 1 (2013). IEC publication 60335-1 is copyrighted by the IEC. This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts

41、 and support of Industry Associations Cmara Nacional de Manufacturas Elctricas (CANAME), the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), and the Association of Home Appliance Manufacturers (AHAM), and of t

42、he Technical Harmonization Sub-Committee (THSC 61D WG1) of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standa

43、rd. This standard was reviewed by the CSA Subcommittee on Safety of Household Electrical Appliances, 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 approve

44、d 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 Institute (ANSI) as an American National Standard. Application of Standard Where reference i

45、s 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 remains the responsibility of the users of the standard to judge its

46、suitability for their particular purpose. This is the CAN/CSA-C22.2 No. 60335-1 Standard for Safety of Household and Similar Appliances, Part 1: General Requirements. This CSA Group Part 1 is to be used in conjunction with the appropriate CSA Group Part 2 Standard, which contains clauses to suppleme

47、nt or modify the corresponding clauses in the Part 1, to provide relevant requirements for each type of product. This is the UL Standard forSafety of Household and Similar Appliances, Part 1: General Requirements. This UL Part 1 is to be used in conjunction with the appropriate UL Part 2 Standard, w

48、hich contains clauses to supplement or modify the corresponding clauses in the Part 1, to provide relevant requirements for each type of product.
