IEC 60350-1

IEC 60350-1:2023 specifies methods for measuring the performance of electric cooking ranges, ovens, steam ovens, and grills for household use. This document is also applicable to portable appliances with similar functionalities that were previously covered by the withdrawn IEC 61817. The ovens covered by this document can be with or without microwave function. Manufacturers are expected to define the primary cooking function of the appliance – microwave function or thermal heat. The primary cooking function is 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 is measured as far as it is possible. For measurement of energy consumption and time for heating a load (see Clause 8), this document is furthermore not applicable to:
- microwave combination function;
- ovens with reciprocating trays or turntable;
- small cavity ovens (see 3.16);
- ovens without adjustable temperature control;
- heating functions and eco functions other than defined in this document;
- appliances with only solo steam function.
This document does not apply to microwave ovens (IEC 60705). This document defines the main performance characteristics of these appliances that are of interest to the user and specifies methods for measuring these characteristics.
This document does not specify a classification or ranking for performance. This document does not deal with safety requirements (IEC 60335-2-6 and IEC 60335-2-9). Appliances covered by this document can be built-in or for placing on a working surface or the floor. There is no measurement method for the energy consumption for grilling and steam functions available. This third edition cancels and replaces the second edition published in 2016 and Interpretation Sheet 1:2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) new definitions for heating function, eco function and definitions relevant for low power mode considerations are amended in Clause 3;
b) order of clauses is changed;
c) revision of 5.3;
d) update of 6.2 in order to improve the reliability of volume measurement;
e) removal of 6.7, Level of shelf;
f) revision of Clause 7 concerning the accuracy of eco functions with residual heat use;
g) revision of Clause 8 in order to improve the reliability of the method for measuring the energy consumption, especially regarding anti-circumvention;
h) unique energy consumption measurement for all heating functions and eco functions with an indication of the energy consumption for a temperature increase of 165 K (compared to 155 K currently for forced air circulation function, for example), which results in higher energy consumption values compared to the previous edition;
i) Ry replaced by L* in Clause 9 and reference to IEC TS 63350;
j) cooking time for reference measurement introduced for broccoli in Clause 10;
k) yellow part replaced by hue angle value in Clause 10;
l) requirements for digital assessment (see former 7.5.3.6.3) are obsolete as specified in IEC TS 63350;
m) revision of Clause 14 (Consumption measurement of low power modes, previous Clause 12);
n) former Annex G (informative) is cancelled due to the fact that this method for measuring an associated activity has been not applied;
o) former Annexes B and F are obsolete, up-to-date shade charts are specified in IEC TS 63350;
p) former Annex E will be substituted by a supporting document located on the IEC's website.
