This part of IEC 60350 specifies methods for measuring the performance of electric cooking ranges, ovens, steam ovens, and grills for household use.
The ovens covered by this standard may be with or without microwave function.
Manufacturers should define the primary cooking function of the appliance – microwave function or thermal heat. The primary cooking function should be measured with an existing method according to energy consumption. If the primary cooking function is declared in the instruction manual as a microwave function, IEC 60705 is applied for energy consumption measurement. If the primary cooking function is declared as a thermal heat, then IEC 60350-1 is applied for energy consumption measurement.
If the primary function is not declared by the manufacturer, the performance of the microwave function and thermal heat should be measured as far as it is possible.
NOTE 1 For measurement of energy consumption and time for heating a load (see 7.4), this standard is furthermore not applicable to:
microwave combination function;
ovens with reciprocating trays or turntable;
small cavity ovens;
ovens without adjustable temperature control;
heating functions other than defined in 3.12 to 3.14;
appliances with only solo steam function (3.15).
NOTE 2 This standard does not apply to
microwave ovens (IEC 60705),
portable appliances for cooking, grilling, steaming and similar functions (IEC 61817).
This standard defines the main performance characteristics of these appliances which are of interest to the user and specifies methods for measuring these characteristics.
This standard does not specify a classification or ranking for performance.
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.
NOTE 4 This standard does not deal with safety requirements (IEC 60335-2-6 and IEC 60335-2-9).
NOTE 5 Appliances covered by this standard may be built-in or for placing on a working surface or the floor.
NOTE 6 There is no measurement method for the energy consumption for grilling and steam functions available.
