38、ardrecognizesthe internationally accepted levelof protection against hazardssuchas electrical, mechanical, thermal,fire and radiation of appliances when operated as in normal use taking intoaccount the manufacturers instructions. It also coversabnormalsituations thatcan be expectedinpractice and tak

39、es into account the way in whichelectromagnetic phenomena can affect the safe operation of appliances.This standard takes into accountthe requirements of IEC 60364 as far as possible sothatthere is compatibilitywith the wiring ruleswhen the appliance is connected to the supply mains. However, nation

40、al wiring rules may differ.If an appliance within the scope of this standard also incorporates functions that are coveredfar as is reasonable. If applicable, the influence of one function on the other is taken into account.An appliance that complieswith the text of this standard will not necessarily

41、 be considered to comply with the safetyprinciples of the standard if, when examined and tested,itis found tohave other features that impair the level of safetycovered bythese requirements.An appliance employing materials or having forms of construction differing from those detailedin the requiremen

42、ts of this standard may be examined and testedaccordingto theintentofthe requirements and, if foundtobe substantially equivalent, may be considered to complywith the standard. in Part1, Part 1 applies. NOTE 1 not necessary to specify particular requirements for the appliance in question over and abo

43、ve the generalrequirements.This standard isa product family standard dealingwith the safety of appliancesand takesprecedence over horizontal andgeneric standards covering the same subject.NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken intocons

44、ideration when developing the general and particular requirements for the IEC 60335 series of standards. Forexample, in the case of temperature requirements for surfaces on many appliances, generic standards, such asPage 6by another Part 2 of IEC 60335, the relevant Part 2 is applied to each functio

45、n separately, asWhen aPart 2 standard does notincludeadditional requirements to coverhazards dealt withThis means that the technical committees responsible for the Part 2 st andards have determined that it isISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 orPart 2 standards.BS

47、 heaters and theirassociated control units, for household and similar purposes, their rated voltage being notmore than 250 V.Appliances not intended for normal householduse,but that nevertheless maybe a source ofdanger to the public, such as appliances intended to be used in hotels, are within the s

48、cope ofthis standard. As far asis practicable, this standard deals with the common hazardspresented byappliances that are encountered by all persons in and around the home. However, in general,it does not take into accountNOTE 101 Attention is drawn to the fact that for appliances intended to be use

49、d in vehicles or onboard ships or in aircraft, additional requirements may benecessary; in many countries additional requirements are specified by the national health authorities, the nationalauthorities responsible for the protection of labour, the national water s upply authorities and similar authorities.NOTE 102 This standard does not apply to appliances for medical purposes (IEC 60601); intended for immersion in water during use.2 Normative referencesThis clauseof Part 1 is applicable except
