20、 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 as to convert it into the European Standard: Safety requirements for electric humidifiers intended for use with heating, ventilation, or

21、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 standard states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. NOTE 1 The following numbe

22、ring 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 numbered starting from 101, including those in a replaced clause or subclause; - additional annexes

23、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 print types are used: - requirements: in roman type; - test specifications: in italic type; - notes: in small roman type. Words in bold in

24、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 conditions causing a deviation from this European Standard, other than those listed in Annex ZA to EN 60335-1. There are no national deviat

25、ions 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 NOTE In this document, p is used in the margin to indicate instructions for preparing the printed version. _ Page2 EN60335288:2002License

For pr

27、oducts 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 Machinery Directive ar

36、UCTION It has been assumed 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, th

37、ermal, fire and radiation 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 compatibi

38、lity with the wiring rules 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 se

39、parately, as far as is 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

40、 complies with the text 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

41、forms of construction 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.

43、 clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric humidifiers intended for use with heating, ventilation, or air-conditioning systems in household, commercial, and light industrial applications (and may include large stand-alone commercial

44、equipment) which operate according to the evaporative or atomization system, water-injection, steam and the like, their maximum rated voltage 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 t

45、he humidifiers covered by this standard are covered in IEC 60335-2-40. As far as is practicable, this standard deals with the common hazards 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

46、 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 on board ships or aircraft, additional requirements may be necessary; in many countries, additional requ

47、irements are specified by national health authorities, national authorities responsible for the protection of labour and similar authorities. NOTE 103 This standard does not apply to humidifiers without room heating, ventilation or air-conditioning equipment intended exclusively for household use (I

48、EC 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 a corrosive or explosive atmosphere (dust, vapour or gas); humidifiers intended for medical purposes (see IEC 60601). 2 Nor
