36、sprovisions is entrusted toappropriately qualified and experienced persons.This standard takes into account the requirementsof IEC60364 as faras possible so thatthere is compatibilitywith the wiring ruleswhen the appliance is connected to the supply mains. However,national wiring rules maydiffer.If
37、an appliance within the scope of this standard also incorporates functions that are coveredby anotherpart 2 ofIEC 60335, the relevant part2 is applied to eachfunctionseparately, asfar as is reasonable. If applicable, the influence of one function on the other is taken into account.An appliance that
38、complieswith the text of this standard willnot necessarily be considered to complywith the safetyprinciples of the standardif,when examined and tested,itis found tohave other features thatimpair thelevel of safetycovered bythese requirements.An appliance employing materialsor having forms of constru
39、ction differing from those detailedin the requirements of this standard maybeexamined and testedaccordingto theintentofthe requirements and, if foundtobe substantiallyequivalent, maybe consideredto complywith the standard. When a part 2 standard does notincludeadditional requirements to coverhazards
40、 dealtwithin Part1, Part 1 applies. NOTE1 This means that the technical committees responsible for the part2 standards have determined that it isnot necessary to specify particular requirements for the appliance in question over and above the generalrequirements.This standard isa product family stan
41、darddealingwith the safetyof appliancesand takesprecedence over horizontal andgenericstandards covering the same subject.NOTE2 Horizontal and generic standards covering a hazard are not applicable since they have been taken intoconsideration when developing the generaland particular requirements for
42、 the IEC 60335 series of standards. Forexample, in the case of temperature requirements for surfaces on many appliances, generic standards, such asISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.This standard recognizestheinternationally acceptedlevel ofpro
43、tectionagainst hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal use taking into account the manufacturers instructions. It also covers abnormalsituations that can be expected in practice and takes into account the way in whichelectromagneti
