mechanical moving parts, a risk assessment in accordance with the Machinery Directive, 98/37/EC, has shown that the risks are mainly of electrical origin and consequently 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 Endorsement

60335-2-9:2003+A13:2010 (E) 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, mechanical, thermal, fire and radiation of appliances when operated as in normal use taking into account the manufacturer's 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 appliances." 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 incorporates functions that are covered by another part of IEC 60335, the relevant part 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 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 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 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 according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the standard Page 23 BS EN 60335-2-9:2003+A13:2010 EN EN 60335-2-9:2003+A13:2010 (E) BS 60335-2-9:2003+A13:2010 EN 60335-2-9:2003+A13:2010 (E) Appliances are tested empty Lids and doors are open or closed, whichever is more unfavourable Detachable parts are in position or removed, whichever is more unfavourable Hotplates are operated without a vessel and with the controls adjusted to the highest setting Induction hotplates are operated under the conditions of Clause 11 but with empty vessels, controls being adjusted to the highest setting Cookers are only tested with the heating unit that results in the most unfavourable conditions, their controls being adjusted to the highest setting However ovens are operated if they not have an indicating lamp to show when they are switched on, controls being adjusted to the highest setting NOTE 101 A lamp used for illuminating the oven, which is visible through the door and is automatically switched on and off with the oven, is considered to be an indicating lamp 19.4 Addition: Air-circulating fans of food dehydrators are disconnected 19.8 19.10 Not applicable Not applicable 19.11.2 Addition: For appliances having electronic controls, the fault conditions a) to f) are also simulated with the appliance supplied at rated voltage but with the controls switched off Heating elements shall not become energized. 19.13 Addition: During the test of 19.102 any flames or smoke from the bread are ignored The temperature rise of the windings of induction hotplates shall not exceed the values specified in 19.7 The electric strength test of induction hotplates is carried out immediately after switching off the appliance 19.101 Toasters are operated at rated power input and under normal operation, but without bread, for six cycles of operation The appliance is then allowed to cool to approximately room temperature This test is carried out 500 times The mechanism shall operate satisfactorily and no sustained arcing shall occur Electrical connections shall not work loose and the appliance shall withstand the electric strength test of 16.3 NOTE Forced cooling may be used NOTE A simulated load may be necessary to operate the mechanism NOTE Subclause 19.13 does not apply 19.102 Toasters, loaded with the bread specified for normal operation, are operated at rated power input The ejector mechanism is prevented from releasing and the supply is maintained to the heating elements after the timer has completed its cycle The test is terminated after any fire has extinguished, after which any residual bread is removed from the toaster 19.103 Induction hotplates are supplied at rated voltage and operated with a steel disk placed on the centre of the cooking zone The disk has a thickness of mm and the smallest diameter, rounded up to the nearest centimetre, which allows the appliance to operate PageEN 24 60335-2-9:2003+A13:2010 BS EN

control that limits the temperature during the test of Clause 11 shortcircuited NOTE If the appliance incorporates more than one control, they are short circuited in turn The temperature rise of the oil shall not exceed 270 K 20 Stability and mechanical hazards This clause of Part is applicable except as follows l 20.2 Add the following requirement: Appliances are fully assembled as in normal operation without any parts removed Replace the 1st paragraph of compliance by: Compliance is checked by inspection, by the tests of 21.1 and by means of: – a test probe that is similar to test probe B of EN 61032 but having a circular stop face with a diameter of 50 mm, instead of the non circular face, applied with a force of N; and – test probe 18 of EN 61032, applied with a force of 2,5 N.m 20.101 Ovens having doors with a horizontal hinge at their lower edge and on which a load is likely to be placed shall have adequate stability l Compliance is checked by the following test The oven is placed on a horizontal surface with the door open and a mass of 3,5 kg is gently placed on the geometric centre of the door NOTE A sandbag may be used for the load The oven shall not tilt This test is not carried out on ovens with doors having a dimension less than 225 mm from the hinge to the opposite edge or on ovens with doors which cannot support dishes in the fully open position.m 21 Mechanical strength This clause of Part is applicable except as follows !21.1 Addition: For appliances intended for outdoor use, the impact energy is increased to 0,7 J." If the appliance incorporates visibly glowing heating elements enclosed in glass tubes, the blows are applied to the tubes as mounted in the appliance if they are – located at the top of the oven and accessible to test probe 41 of IEC 61032;
