the cooling down period G.1 Purpose The purpose of this test is to measure the energy consumption of the cooling down period For cooking ranges, ovens and steam ovens the energy consumption of the cooling down period is measured, see Figure G.1 Set to off mode Energy consumption according to 7.4 P (W) Cooling down period for 60 ±1 Transition to low power mode Unload oven and close the door 30 s ± s after switching off Cooling down period T (min) IEC Figure G.1 – Phases of energy consumption measurement – Example G.2 Preliminary measurements For measuring the energy consumption of the cooling down period a pre-test to fix the relevant temperature setting is carried out A thermocouple is placed in the empty appliance as described in Clause The temperature control is set to positions where the mean oven temperature rises ∆T2i , as defined in Table 1, can be expected The appliance is run for some time without changing the setting until steady state conditions are reached The oven temperature is determined as the arithmetic mean between the maximum and minimum temperatures at steady state conditions NOTE Steady conditions are considered to be attained after five cycles of the thermostat or h, whichever is shorter The temperature control setting is adapted until the arithmetic mean between the maximum and minimum temperature is ∆T2i ± K This temperature control setting is noted for measuring the energy consumption of the cooling down period BS EN 60350-1:2016 IEC 60350-1:2016 © IEC 2016 BS EN 60350-1:2016 IEC 60350-1:2016 © IEC 2016 – 66 – – 67 – The appliance is cooled down to ambient temperature G.3 Measuring the energy consumption of the cooling down period The procedure to prepare the brick stated in 7.4.2.2 and 7.4.2.3 is followed The brick is positioned in the appliance according to 7.4.3.1 The appliance is switched on within from the removal of the brick from the refrigerator The temperature control is set to the position determined in Clause G.2 The appliance is operated for the time t i determined in ∆T0 7.4.4.2 The measurement shall be started by setting the appliance to off mode The brick is removed and the door shall be closed after (30 ± 2) s The measurement of the low power energy consumption is started immediately when the appliance is set to off mode If the appliance doesn´t offer an off mode it is set to standby mode The measurement is stopped after (60 ± 1) independently of whether the ventilation stops automatically The energy consumption for the cooling down period is noted in W⋅h for each heating mode according to Table Ensure that the following conditions remain relevant for the duration of the measurement: • appliance connected to mains power for the duration of the test; • no network is connected to the product BS EN 60350-1:2016 IEC 60350-1:2016 © IEC 2016 BS EN 60350-1:2016 IEC 60350-1:2016 © IEC 2016 – 67 – – 68 – Annex H (informative) Check of applied microwave energy during the measurement according to 7.4 H.1 General Heating up the brick according to 7.4 shall only be done with thermal heating It is not allowed to switch on a magnetron, not even for a short period The sophisticated method to check possible applied microwave energy during the energy consumption measurement according to 7.1 is to prove whether the magnetron is switched on and off Depending on the design of the appliances it is not always possible to determine clearly whether the microwave energy is switched on during the long lasting heating up process Therefore the following method can be used in a pre-test H.2 Procedure A filament lamp with a rated current of 12 mA and a rated voltage of less than V with bended connecting wires is used The lengths of the wires are approximately half of the wave length of the microwave so the current distribution is maximum in the middle where the filament of the lamp is positioned (see Figure H.1) volt c ∼ 12 mA x IEC Key c connecting wire x in the range of 50 mm to 60 mm Figure H.1 – Filament lamp The brick is prepared as described in 7.4.2.3 and placed in the appliance as described in 7.4.3.1 The filament lamp is placed on the upper surface of the wet brick The appliance is switched on and operated according to 7.4.3.1 for at least the time which is necessary to have a temperature rise in the brick of 55 K The appliance is then switched off and the filament lamp is tested If microwave energy was applied, the electric field during microwave operation will induce currents much more than 12 mA, thereby damaging the filament The lamp can be tested with a resistance-test equipment or with a small tester for LED lamps The lamp is put into a socket and the filament will light up if it is not damaged Otherwise this means microwave energy was applied BS EN 60350-1:2016 IEC 60350-1:2016 © IEC 2016 BS EN 60350-1:2016 IEC 60350-1:2016 © IEC 2016 – 68 – – 69 – Annex I (informative) Marking the temperature setting for checking the oven
