32、armonized CSA Group and UL Standard for Household Dishwashers. It is the sixth edition ofCAN/CSA-C22.2 No. 167, and the ninth edition of UL 749. This edition of CSA C22.2 No. 167 supersedesthe previous edition published in 2008.This harmonized Standard was prepared by CSA Group and Underwriters Labo
33、ratories Inc. (UL).The efforts and support of the Canadian Appliance Manufacturers Association (CAMA) and theAssociation of Home Appliance Manufactures (AHAM) are gratefully acknowledged.This Standard is considered suitable for use for conformity assessment within the stated scope of theStandard.Thi
34、s Standard was reviewed by the CSA Subcommittee on Household Dishwashers, under the jurisdictionof the Technical Committee on Consumer and Commercial Products and the CSA Strategic SteeringCommittee on Requirements for Electrical Safety, and has been formally approved by the CSA TechnicalCommittee.T
35、his standard has been approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Where reference is made to a specific number of samples to be tested, the specified number shall beconsidered a minimum quantity.Note: Although the intended primary application of this
36、standard is stated in its scope, it is important to note thatit remains the responsibility of the users of the standard to judge its suitability for their particular purpose.Level of harmonizationThis standard is published as an identical standard for CSA Group and UL.An identical standard is a stan
37、dard that is exactly the same in technical content except for nationaldifferences resulting from conflicts in codes and governmental regulations. Presentation is word for wordexcept for editorial changes.InterpretationsThe interpretation by the standards development organization of an identical or e
38、quivalent standard isbased on the literal text to determine compliance with the standard in accordance with the proceduralrules of the standards development organization. If more than one interpretation of the literal text has beenidentified, a revision is to be proposed as soon as possible to each
39、of the standards developmentorganizations to more accurately reflect the intent.CSA Group Effective DateThe effective date for CSA Group will be announced through CSA Informs or CSA Group CertificationNotice.MARCH 20, 2013CSA-C22.2 NO. 167-13 UL 7496UL Effective DateThe effective date for UL is bein
