15、NAL ELECTROTECHNICAL COMMISSION_HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2-88: Particular requirements for humidifiers intended for usewith heating, ventilation, or air-conditioning systemsFOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for s

16、tandardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publ

17、ishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this

18、preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternatio

19、nal consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical r

20、eports or guides and they are accepted by the NationalCommittees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence

21、between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) Attenti

22、on is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.This part of International Standard IEC 60335 has been prepared by subcommittee 61D:Applianc

23、es for air-conditioning for household and similar purposes, of IEC technicalcommittee 61: Safety of household and similar electrical appliances.This second edition cancels and replaces the first edition published in 1997. It constitutes atechnical revision.The text of this part of IEC 60335 is based

24、 on the following documents:FDIS Report on voting61D/117/FDIS 61D/122/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and itsamendments

25、. It was established on the basis of the fourth edition (2001) of that standard.NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as toconvert that publication into the IEC standard: Safety re

26、quirements for electric humidifiersintended for use with heating, ventilation, or air-conditioning systems.60335-2-88 IEC:2002(E) 5 When a particular subclause of Part 1 is not mentioned in this part 2, that subclause appliesas far as is reasonable. When this standard states “addition“, “modificatio

27、n“ or “replacement“,the relevant text in Part 1 is to be adapted accordingly.NOTE 2 The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or involve notes in Part 1, they are n

28、umbered starting from 101, includingthose in a replaced clause or subclause; additional annexes are lettered AA, BB, etc.NOTE 3 The following print types are used: requirements: in roman type; test specifications: in italic type; notes: in small roman type.Words in bold in the text are defined in Cl

29、ause 3. When a definition concerns an adjective, the adjective andassociated noun are also in bold.The committee has decided that the contents of this publication will remain unchanged until2004. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.

30、The following differences exist in the countries indicated below. 6.1: class 01 appliances are allowed (Japan). 6.1: class 0 and 01 appliances are allowed (South Africa, Poland).A bilingual version of this publication may be issued at a later date. 6 60335-2-88 IEC:2002(E)INTRODUCTIONIt has been ass

31、umed in the drafting of this International Standard that the execution of itsprovisions is entrusted to appropriately qualified and experienced persons.This standard recognizes the internationally accepted level of protection against hazards suchas electrical, mechanical, thermal, fire and radiation

32、 of appliances when operated as innormal use taking into account the manufacturers instructions. It also covers abnormalsituations that can be expected in practice.This standard takes into account the requirements of IEC 60364 as far as possible so thatthere is compatibility with the wiring rules wh

33、en the appliance is connected to the supplymains. However, national wiring rules may differ.If an appliance within the scope of this standard also incorporates functions that are coveredby another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, asfar as is reasonable

34、. If applicable, the influence of one function on the other is taken intoaccount.This standard is a product family standard dealing with the safety of appliances and takesprecedence over horizontal and generic standards covering the same subject.An appliance that complies with the text of this stand

35、ard will not necessarily be considered tocomply with the safety principles of the standard if, when examined and tested, it is found tohave other features that impair the level of safety covered by these requirements.An appliance employing materials or having forms of construction differing from tho

36、se detailedin the requirements of this standard may be examined and tested according to the intent ofthe requirements and, if found to be substantially equivalent, may be considered to complywith the standard.60335-2-88 IEC:2002(E) 7 HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFTEY Part 2-88: Part

37、icular requirements for humidifiers intended for usewith heating, ventilation, or air-conditioning systems1 ScopeThis clause of Part 1 is replaced by the following.This International Standard deals with the safety of electric humidifiers intended for use withheating, ventilation, or air-conditioning

38、 systems in household, commercial, and light industrialapplications (and may include large stand-alone commercial equipment) which operateaccording to the evaporative or atomization system, water-injection, steam and the like, theirmaximum rated voltage being not more than 250 V for single-phase app

39、liances and 600 V forall other appliances.NOTE 101 Air-conditioning equipment to be used in conjunction with the humidifiers covered by this standardare covered in IEC 60335-2-40.As far as is practicable, this standard deals with the common hazards presented byappliances that are encountered by all

40、persons in and around the home. However, in general,it does not take into account the use of appliances by young children or infirm persons without supervision; playing with the appliance by young children.NOTE 102 Attention is drawn to the fact that for appliances intended to be used in vehicles or

41、 on board ships or aircraft, additional requirements may benecessary; in many countries, additional requirements are specified by national health authorities, national authoritiesresponsible for the protection of labour and similar authorities.NOTE 103 This standard does not apply to humidifiers wit

42、hout room heating, ventilation or air-conditioning equipment intended exclusively for householduse (IEC 60335-2-98); appliances designed exclusively for industrial processing; appliances intended to be used in locations where special conditions prevail, such as the presence of acorrosive or explosiv
