31、57 UL 498C4PREFACEThis is the harmonized CSA Group and UL standard for Appliance and Flatiron Plugs. It is the First editionof CAN/CSA-C22.2 No. 57, and the First edition of UL 498C.This harmonized standard was prepared by the CSA Group and Underwriters Laboratories Inc. (UL). Theefforts and support
32、 of the Technical Harmonization Subcommittee for Switch and Outlet Boxes, THSC23B-1, on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), aregratefully acknowledged.This standard is considered suitable for use for conformity assessment within the stated scope o
33、f thestandard.This standard was reviewed by the CSA Inegrated Commitee on Wiring Devices, under the jurisdiction of the CSA Technical Committee on Wiring Devices and the CSA Strategic Steering Committee on requirements for Electrical Safety, and has been formally approved by the CSA Technical Commit
34、tee.This standard has been approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Application 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
35、primary application of this 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 uses the IEC format but is not based on, nor is it considered
36、equivalent to, an IEC standard.This standard is published as an equivalent standard for CSA Group and UL.An equivalent standard is a standard that is substantially the same in technical content, except as follows:Technical national differences are allowed for codes and governmental regulations as we
37、ll as thoserecognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic,geographical, technological, or infrastructural factors, scientific justification, or the level of protection thatthe country considers appropriate. Presentation is word for word except
38、for editorial changes.InterpretationsThe interpretation by the standards development organization of an identical or equivalent standard isbased on the literal text to determine compliance with the standard in accordance with the proceduralrules of the standards development organization. If more tha
39、n one interpretation of the literal text has beenidentified, a revision is to be proposed as soon as possible to each of the standards developmentorganizations to more accurately reflect the intent.APRIL 28, 2017 CSA C22.2 NO. 57 UL 498C 5Flatiron and Appliance PlugsINTRODUCTION1 Scope1.1 These requ
