gas-fired domestic ovens which are capable of utilizing gases of group H or group E, possibly after conversion according to instructions for use This European Standard applies to these gas-fired domestic ovens, whether they are separate appliances or component parts of domestic cooking appliances This European Standard also applies to domestic appliances that can utilize gas and/or electrical energy to provide heat for cooking when the ovens are utilizing gas energy to provide heat for cooking, but not when electric energy is used to provide any or all of the heat for cooking in the oven It is not applicable to: — microwave combination ovens; — small cavities ovens (3.2); — oven cavities not provided with devices to detect and control the temperature for the preparation of food; — cooking modes others than defined in 3.1.1 and 3.1.2; — ovens connected to a chimney in which the gas energy for cooking provides, by design, also space and/or water heating; — appliances designed for

consumption and heating time Heating of the load (7.2) BS EN 15181:2017 EN 15181:2017 (E) General conditions for measurements 5.1 General According to good laboratory practice, before installation, it shall be checked that the appliance is free from damage and complies with EN 30-1-1:2008+A3:2013, 6.1.1, Soundness, EN 30-1-2 or EN 30-1-4, as applicable The instructions for use regarding installation of the oven shall be followed Prior to every test, the whole appliance (this includes the material and the insulation) shall be at ambient temperature In multiple cavity appliances, each oven cavity shall be measured separately Only the cavity measured shall be switched on In case an oven has several cooking modes as described in Clause 3, the manufacturer can choose the variant to be tested This shall be reported (see Clause 8) Unless otherwise specified, measurements are conducted under the following conditions: 5.2 Ambient temperature The tests are carried out in a substantially draught-free room in which the ambient temperature is maintained at (23 ± 2) °C during the complete test Prior to the measurement the whole appliance (this includes the material and the insulation) shall be at ambient temperature of (23 ± 2) °C A change in the ambient temperature of the room during the test could affect the results Care should be taken during the test to ensure that the ambient temperature is as steady as possible This ambient temperature is measured at a point that is at the same height as the centre of the calculated oven volume of the oven cavity and at a distance of 0,5 m diagonally from one of the front edges of the appliance; see Figure The measurement of the ambient temperature shall not be influenced by the oven itself or by any other appliance Dimensions in millimetres Key top view oven thermocouple Figure — Position of the thermocouple BS EN 15181:2017 EN 15181:2017 (E) 7.2.3 Measurement 7.2.3.1 Procedure Each appliance is tested in accordance with the setting values given in Table With the appliance at ambient temperature in accordance with 5.2, the brick, prepared according to 7.2.2, is placed in the geometric centre of the calculated oven volume with its largest surface centrally on the grid delivered with the oven, with the thermocouples on the upper side The grid is inserted into the shelf support level of the oven which ensures that the centre of the brick comes as close as possible to the centre but not higher (if this arrangement is not possible, use an arrangement which is as close to the centre as possible) than the centre of the calculated oven volume The longer axis of the brick shall be parallel with the oven front Where the grid can be inserted in two different positions (e.g upside down gives a different height), the position should be such as to ensure that the centre of the brick comes as close as possible to, but not higher than, the centre of the calculated oven volume The thermocouples shall be led through the door gap in a way that the door is completely closed without applying additional force The measurement shall be started by switching on the oven within three minutes from the removal of the brick from the refrigerator The temperature control is set to positions where the mean oven temperature rises ∆Tki… as defined in Table can be expected ∆Tki… is the difference between the average ambient temperature and the actual oven temperature (measured in 7.2.3.2), k = 1, 2, The temperature in the centre of the oven at the beginning of the test (Toi) in °C is determined as described in 7.1 NOTE To avoid possible modification of the temperature control set, it is suggested to fix the knob at the control temperature The average ambient temperature (Tav) during the test is determined by the arithmetic mean of the ambient temperatures measured in accordance with 5.2 at the beginning of the test (Tr1) (i.e when switching on the oven) and when the two thermocouples in the brick have reached a centre temperature rise of 55 K (Tr2) Table — Oven settings Oven temperature rise ∆T1i ∆T2i ∆T3i a Heating functions Conventional “ic” Forced air “if” (140 −0/+10) K (150 ± 5) K (220 ± 5) Ka (180 ±

oven and the oven is run for some extra i time without changing the setting The oven temperature Tk, measured is determined in line with 7.1 as the arithmetic mean between the maximum and minimum temperatures at steady-state conditions 14 BS EN 15181:2017 EN 15181:2017 (E) NOTE Ovens with thermostats according to EN 257: steady-state conditions are deemed to be achieved when the temperature does not change by more than ± K over a period of 10 or h after removal of the brick NOTE Ovens with automatic burner control system according to EN 298: steady-state conditions are considered to be achieved when the arithmetic mean value between the maximum and the minimum temperature of each cycle of the control device does not change by more than ± K over a period of at least cycles 7.2.3.3 Checking the correspondence between set and measured oven temperature Immediately after the test of 7.2.3.2 the temperature setting Tksi shall be noted, where Tksi is the temperature setting of the knob controlling the thermostat and/or the oven control display (s - setting) In case when the Tksi does not correspond to a value (see, as an example, Figure 4) or a reference marked on the knob or panel, the value of Tksi is obtained by applying the polar coordinate paper between the next marked values or references before and after Tksi Figure — Setting of the thermostat knob NOTE If the setting of the knob is marked by means of a number (e.g 140), the knob is positioned at the geometrical centre of the circle circumscribing the figure If the setting is marked by symbols (e.g * or • or ♦), figures or words the relevant set temperature should be indicated in the instructions for use NOTE i In case when Tks corresponds to a value or a reference marked on the knob or panel or on the oven control display, i Tk, measured corresponds to Tof If the temperature steps are not clearly marked, the setting temperature should be determined by the angle considering the visible marks on the knob using polar coordinate paper (see Annex D) i The measured oven temperature Tk, measured stated i The difference between Tksi and Tk, measured calculated according to Formulae (1) and (2), where n

the load The gas energy consumption, Eki , is determined using the formula: c × Hs Eki= V where Vc Hs (3) is the volume of dry gas consumed, corrected to reference conditions (15 °C and 013,25 mbar), in cubic metres; is the gross calorific value of the dry test gas under reference conditions (15 °C and 013,25 mbar), in Megajoule per cubic metre (See EN 30–1–1:2008+A3:2013, 3.3.1.5) Where the test gas G20 has a methane content of less than 99,5 % care should be taken to ensure that the calorific value of this gas is known and used in the above formula Vc is determined from the measured volume, by the following formula: pa + p − pw Vc = Vmes ⋅ where Vmes pa p pw tg 013, 25 ⋅ 288,15 273,15 + tg (4) is the measured gas volume, in cubic metres; is the atmospheric pressure, in millibars; is the gas supply pressure measured at the same point as that used in the heat input determination, in millibars; is the partial vapour pressure, in millibars; is the gas temperature measured at the same point as that used in the heat input determination, in degrees Celsius The gas energy consumptions E1i , E2i , E3i correspond to the temperatures of Table 1, as appropriate The following data are measured: — the gas volume Vmes and the time(s) tki… in and s, as appropriate, when the two thermocouples in the brick reach a temperature rise of 55 K, k = 1, 2, 3; — centre temperatures of the brick in °C; — ambient temperature at the start of the test (when the oven is switched on) and at the end of the test (i.e when the two thermocouples in the brick have reached 55 K temperature rise) in °C 7.2.3.5 Checking of the water loss At the end of the test the amount of the water loss in g (Wloss) is determined taking into account the mass of the wet brick mw, measured according to 7.2.2 and the mass (me) measured immediately after the removal of the brick from the oven, by calculating Wloss = mw - me The weighing machine should be protected from the effects of the hot brick After each test the oven shall be cleaned 16 BS EN 15181:2017 EN 15181:2017 (E) 7.2.3.6 Acceptance verification of the test results (set temperature and confidence of the measurement) Results of the tests according to 7.2.3.1 shall only be accepted if: a) the mean temperature rises ∆Τki are within the temperatures specified in Table 1, and b) the standard deviation σi as defined in Formula (5) is below 0,25 MJ
