It is the fourth edition of CSA-C22.2No. 104 and the fifth edition of UL 998. This harmonized standard has been jointly revised on
41、April 4,2016. For this purpose, CSA Group and UL are issuing revision pages dated April 4, 2016.This harmonized Standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). Theefforts and support of the Air Conditioning and Refrigeration Institute (ARI) and the Heating, Refrigeratinga
42、nd Air Conditioning Institute of Canada (HRAI) are gratefully acknowledged.This Standard is considered suitable for use for conformity assessment within the stated scope of theStandard.This Standard was reviewed by the CSA Subcommittee on Humidifiers, under the jurisdiction of the CSATechnical Commi
43、ttee on Consumer and Commercial Products and the Strategic Steering Committee onRequirements for Electrical Safety, and has been formally approved by the CSA Technical Committee.This standard has been approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Applic
44、ation of StandardWhere reference is made to a specific number of samples to be tested, the specified number isconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated in its scope, it is important tonote that it remains the responsibility of the users
45、of the standard to judge its suitability for their particularpurpose.Level of HarmonizationThis standard uses the IEC format but is not based on, nor is it considered equivalent to, an IEC standard.This standard is published as an identical standard for CSA Group and UL.An identical standard is a st
46、andard 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
47、 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 than one interpretation of the literal text has beenidentified, a revision is to be proposed as soon as possible to eac
48、h of the standards developmentorganizations to more accurately reflect the intent.APRIL 4, 2016CSA C22.2 NO. 104-11 UL 9986HUMIDIFIERSINTRODUCTION1 Scope1.1 These requirements cover humidifiers rated 600 V or less, and intended to be used in accordancewith the National Electrical Code (NEC), ANSI/NF
49、PA 70, and the Rules of the Canadian Electrical Code(CEC), Part I, C22.1.1.2 These requirements cover humidifiers intended for residential and commercial use. This includeshumidifiers of the centrifugal atomizing type, evaporative-media type, water-injection type, steam type,and the like. The humidifiers may be for installation in a room, mounted on a wall or a ceiling, or for ductor plenum mounting.1.3 These requirements apply to equipment that includes an electric heating element to heat air or water,or
