38、6 BS EN 60335-2-96:2002+A2:2009 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. It also covers abnormal This standard takes into account the requirements of IEC 60364

39、 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 incorporates functions that are covered by another part 2 of IEC 60335, the

40、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. An appliance that complies with the text of this standard will not necessarily be considered to comply with the safety principles of the s

41、tandard if, when examined and tested, it is found to have other features which impair the level of safety covered by these requirements. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and tested acco

42、rding to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the standard. Page7situations that can be expected in practice and takes into accounttheway in which electromagnetic phenomena can affect the safe operation of appliances. When a pa

43、rt 2 standard does not include additional requirements to 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

44、 over and above the general requirements. 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. NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they hav

45、e been taken into consideration when developing the general 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

46、 to Part 1 or part 2 standards.

This International Stand

47、ard deals with the safety of flexible sheet heating elements intended to be incorporated into the building to heat the room in which they are located, their rated voltage being not more than 250 V for single-phase installations and 480 V for other installations. Flexible sheet heating elements are c

NOTE 101 Attention is drawn to the fact that in many countries different wiring rules apply; for heating units intended to b

49、e used in vehicles or on board ships or aircraft, additional requirements may be necessary; in many countries 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.
