38、persons. This standard recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in This standard takes into account the requirements of IEC 60364 as far as possible so that there is compatib

39、ility 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 s

40、eparately, 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 standard if, when examined and tested, it is f

41、ound to have other features that 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 according to the intent of the requirements and, i

42、f found to be substantially equivalent, may be considered to comply with the standard. situations that can be expected in practice and takes into account the way in whichelectromagnetic phenomena can affect the safe operation of appliances. normal use taking into account the manufacturers instructio

43、ns. It also covers abnormal When a part 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 requi

44、rements for the appliance in question 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 haz

45、ard are not applicable since they have 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 sur

46、faces, are not applicable in addition to Part 1 or part 2 standards. #$BS EN 60335-2-73:2003+A2:2009EN 60335-2-73:2003+A2:2009 (E)Page 6HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2-73: Particular requirements for fixed immersion heaters 1 Scope This clause of Part 1 is replaced by the f

47、ollowing. This International Standard deals with the safety of fixed electric immersion heaters for household and similar purposes that are intended for installation in a water tank open to the atmosphere for heating water to a temperature below its boiling point. The rated voltage is not more than

48、250 V for single-phase appliances and 480 V for other appliances. NOTE 101 The water tank may have alternative means for heating water, such as the circulation of hot water supplied from a separate boiler. NOTE 102 Immersion heaters having a rated power input up to 25 kW for incorporation as an alte

49、rnative heating source in central heating boilers are also within the scope of this standard. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. 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 h
