IEC 60350-2005 pdf – Electric cooking ranges, hobs, ovens and grills for household use – Methods for measuring performance.
1 Scope This International Standard defines methods for measuring the performance of electric cooking ranges, hobs, ovens and grills for household use. NOTE 1 Appliances covered by this standard may be built-in or for placing on a working surface or the floor. NOTE 2 This standard does not apply to – microwave ovens (IEC 60705), – portable appliances for cooking, grilling and similar functions * This standard defines the main performance characteristics of these appliances which are of interest to the user and specifies methods for measuring these characteristics. NOTE 3 Some of the tests which are specified in this standard are not considered to be reproducible since the results may vary between laboratories. They are therefore intended for comparative testing purposes only. This standard does not specify requirements for performance. NOTE 4 This standard does not deal with safety requirements (IEC 60335-2-6 and IEC 60335-2-9). NOTE 5 For measurement of energy consumption and time for heating a load (see 8.3), this standard is furthermore not applicable to: − microwave combination ovens; − small cavity ovens; − ovens without adjustable temperature control; − heating functions other than defined in 3.16 to 3.18. 2 Normative references The following referenced documents are indispensable for the application of this document.

4 List of measurements The performance of the appliance is determined by the tests listed in 4.1 to 4.6. 4.1 Dimensions and mass The following measurements are carried out: – overall dimensions (see 6.1); – dimensions of hotplates and cooking zones (see 6.2); – internal dimensions of ovens (see 6.3); – dimensions of shelves (see 6.4); – dimensions of grill grids (see 6.5); – dimensions of warming compartments (see 6.6); – level of hotplates (see 6.7); – distance between the hotplates or cooking zones (see 6.8); – level of the shelf (see 6.9); – mass of the appliance (see 6.10). 4.2 Hotplates and cooking zones The following tests are carried out: – ability to heat water (see 7.1); – ability to control the temperature of a load (see 7.2); – heat distribution (see 7.3). 4.3 Oven The following tests are carried out: – preheating the empty oven (see 8.1); – accuracy of the control (see 8.2); – energy consumption and time for heating a load (8.3); – heat distribution (see 8.4); – ability to supply heat (see 8.5). 4.4 Grill The following tests are carried out: – grilling area (see 9.1); – grilling (see 9.2). 4.5 Warming compartments The following test is carried out: – temperature control and energy consumption (see clause 10).
4.6 Cleaning The following tests are carried out: – spillage capacity of hobs (see 11.1); – cleaning of pyrolytic self-cleaning ovens (see 11.2); – cleaning of ovens with catalytic cleaning (see 11.3). 5 General conditions for the measurements Unless otherwise specified, the measurements are made under the following conditions. 5.1 Test room The tests are carried out in a substantially draught-free room in which the ambient temperature is maintained at 20 °C ± 5 °C. For tests 8.1 and 8.3, (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 usable 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 11. 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. For tests 8.1 and 8.3: − the supply voltage shall be maintained at the main terminal at the rated voltage ±1 %, while the heating elements are switched on; − the supply frequency shall be at the rated frequency ±1 % throughout the test. If a frequency range is indicated, then the test frequency shall be the nominal frequency of the country in which the appliance is intended to be used.
