28、 INTRODUCTION 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, mechani

29、cal, thermal, 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 and takes into account the way in which electromagnetic phenomena can affect the safe operation of app

30、liances. This standard takes into account the requirements of IEC 60364 as far as possible so that there is compatibility 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 incor

31、porates 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 reasonable. If applicable, the influence of one function on the other is taken into account. When a part 2 standard does not include additional requirements to

32、cover hazards dealt with in Part 1, Part 1 applies. NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is not necessary to specify particular requirements for the appliance in question over and above the general requirements. This standard is

33、 a product family standard dealing with the safety of appliances and takes precedence over horizontal and generic standards covering the same subject. NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into consideration when developing the genera

34、l and particular requirements for the IEC 60335 series of standards. For example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards. An appliance that complies

35、 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 forms of

36、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. An investigation by CENELEC TC 61 has shown that all ris

37、ks from products within the scope of this standard are fully covered by the Low Voltage Directive, 2006/95/EC. For products having mechanical moving parts, a risk assessment in accordance with the Machinery Directive, 2006/42/EC, has shown that the risks are mainly of electrical origin and consequen

38、tly this directive is not applicable. However, the relevant essential safety requirements of the Machinery Directive are covered by this standard together with the principal objectives of the Low Voltage Directive.

39、6: Particular requirements for heated carpets and for heating units for room heating installed under removable floor coverings 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of heated carpets and similar appliances; heating units to heat

40、 the room in which they are located and that are intended to be installed directly under a floor covering that is itself intended to be removable; their rated voltage being not more than 250 V for single-phase installations and 480 V for other installations. NOTE 101 Examples of materials used as re

41、movable floor coverings are carpet, cushion vinyl, or loose laid laminate. NOTE 102 Attention is drawn to the fact that in many countries different wiring rules apply; for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary; in many coun

42、tries additional requirements are specified by the national authorities for fire protection, the national authorities for building regulations, the national health authorities, the national authorities responsible for the protection of labour and similar authorities. NOTE 103 This standard does not

43、apply to appliances intended exclusively for industrial purposes; 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); blankets, pads and similar flexible heating appliances (IEC 60335-2-17);

44、heated mats and foot warmers (IEC 60335-2-81); flexible sheet heating systems permanently incorporated in the floor of the building structure (IEC 60335-2-96); flexible heating elements incorporated in other appliances. 2 Normative references This clause of Part 1 is applicable except as follows.
