16、e IEC-CENELEC parallel vote and was approved by CENELEC as EN 60335-2-88 on 2002-12-01. This European Standard replaces EN 60335-2-88:1997. The following dates are applicable: - latest date by which the EN has to be implemented at national level by publication of an identical national standard or by

17、 endorsement (dop) 2003-09-01 - date on which national standards conflicting with the EN have to be withdrawn (dow) 2005-12-01 This part 2 has to be used in conjunction with EN 60335-1, Household and similar electrical appliances Safety Part 1: General requirements. It was established on the basis o

18、f the 2002 edition of that standard. Amendments and revisions of Part 1 have also to be taken into account and the dates when such changes become applicable will be stated in the relevant amendment or revision of Part 1. This part 2 supplements or modifies the corresponding clauses of EN 60335-1, so

19、 as to convert it into the European Standard: Safety requirements for electric humidifiers intended for use with heating, ventilation, or air-conditioning systems. When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. When this standar

20、d states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. NOTE 1 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

21、 or involve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; - additional annexes are lettered AA, BB, etc.; - subclauses, notes and annexes that are additional to those in the IEC standard are prefixed with the letter Z. NOTE 2 The following p

22、rint 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 Clause 3. When a definition concerns an adjective, the adjective and the associated noun are also in bold. There are no special national c

23、onditions causing a deviation from this European Standard, other than those listed in Annex ZA to EN 60335-1. There are no national deviations from this European Standard, other than those listed in Annex ZB to EN 60335-1. Annexes AA and BB are normative and form an integral part of this standard. p

24、 NOTE In this document, p is used in the margin to indicate instructions for preparing the printed version. _ Page2 EN60335288:2002Introduction p Add: An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this standard are fully covered by the Low Voltage Direc

25、tive, 73/23/EEC. For products having mechanical moving parts, a risk assessment in accordance with the Machinery Directive, 98/37/EC, has shown that the risks are mainly of electrical origin and consequently this directive is not applicable. However, the relevant essential safety requirements of the

26、 Machinery Directive are covered by this standard together with the principal objectives of the Low Voltage Directive. _ Endorsement notice The text of the International Standard IEC 60335-2-88:2002 was approved by CENELEC as a European Standard without any modification. _ ACZ xenn (ronitamv)e vitam

33、umed in the drafting of this International Standard that the execution of its provisions is entrusted to appropriately qualified and experienced persons. This standard recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiat

34、ion of appliances when operated as in normal use taking into account the manufacturers instructions. It also covers abnormal situations that can be expected in practice. This standard takes into account the requirements of IEC 60364 as far as possible so that there is compatibility with the wiring r

35、ules when the appliance is connected to the supply mains. However, national wiring rules may differ. If an appliance within the scope of this standard also incorporates functions that are covered by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as far as is

36、 reasonable. If applicable, the influence of one function on the other is taken into account. This standard is a product family standard dealing with the safety of appliances and takes precedence over horizontal and generic standards covering the same subject. An appliance that complies with the tex

37、t of this standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and tested, it is found to have other features that impair the level of safety covered by these requirements. An appliance employing materials or having forms of construction

38、differing from those detailed in the requirements of this standard may be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the standard.

39、LECTRICAL APPLIANCES SAFTEY Part 2-88: Particular requirements for humidifiers intended for use with heating, ventilation, or air-conditioning systems 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric humidifiers intended for us

40、e with heating, ventilation, or air-conditioning systems in household, commercial, and light industrial applications (and may include large stand-alone commercial equipment) which operate according to the evaporative or atomization system, water-injection, steam and the like, their maximum rated vol

41、tage being not more than 250 V for single-phase appliances and 600 V for all other appliances. NOTE 101 Air-conditioning equipment to be used in conjunction with the humidifiers covered by this standard are covered in IEC 60335-2-40. As far as is practicable, this standard deals with the common haza

42、rds presented by appliances that are encountered by all 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 f

43、act that for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary; in many countries, additional requirements are specified by national health authorities, national authorities responsible for the protection of labour and similar authorit

44、ies. NOTE 103 This standard does not apply to humidifiers without room heating, ventilation or air-conditioning equipment intended exclusively for household use (IEC 60335-2-98); appliances designed exclusively for industrial processing; appliances intended to be used in locations where special cond

45、itions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); humidifiers intended for medical purposes (see IEC 60601). 2 Normative references This clause of Part 1 is applicable except as follows.
