IEC 60350-1-2021 Household electric cooking appliances – Part 1: Ranges, ovens, steam ovens and grills – Methods for measuring performance. 4 List of measurements 4.1 Dimensions and mass The following measurements are carried out: – overall dimensions (see 6.1 ); – internal dimensions (see 6.2); – dimensions of shelves and steaming accessories (see 6.4); – dimensions of grill grids (see 6.5); – dimensions of warming compartments (see 6.6); – level of the shelf (see 6.7); – mass of the appliance (see 6.8). 4.2 Oven and combi steam oven The following measurements are carried out: – preheating the empty oven (see 7.2); – accuracy of the control (see 7.3); – energy consumption and time for heating a load (see 7.4); – heat distribution (see 7.5); – ability to supply heat (see 7.6). 4.3 Steam oven and combi steam oven The following measurements are carried out: – ability to supply steam (see 8.1 ); – distribution of steam (see 8.2) – determination of the capacity (see 8.3). 4.4 Grill The following measurements are carried out: – grilling area (see 9.2); – grilling (see 9.3). 4.5 Warming compartments The following measurements are carried out: – temperature control and energy consumption (see Clause 1 0). 4.6 Cleaning The following measurements are carried out: – cleaning of pyrolytic self-cleaning ovens (see 1 1 .1 ); – cleaning of ovens with catalytic cleaning (see 1 1 .2). 5 General conditions for the measurement 5.1 Test room The tests are carried out in a substantially draught-free room in which the ambient temperature is maintained at (20   5) °C. For tests 7.2, 7.4 and 7.5.3, (23 ? 2) °C shall be maintained during the complete test. This ambient temperature is measured at a point that is at the same height as the centre of the calculated volume of the oven cavity in test and at a distance of 0,5 m diagonally from one of the front edges of the appliance (see Figure 1 ). The measurement of the ambient temperature shall not be influenced by the appliance itself or by any other appliance. 5.2 Electricity supply The appliance is supplied at rated voltage 1 %. If the appliance has a rated voltage range, the tests are carried out at the nominal voltage of the country where the appliance is intended to be used. – the supply voltage shall be maintained at the main terminal at the rated voltage...
