DIN EN IEC 60350-1:2024-07

This part of IEC 60350 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document is also applicable to portable appliances with similar functionalities that were previously covered by the withdrawn IEC 61817.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. This document defines the main performance characteristics of these appliances that are of interest to the user and specifies methods for measuring these characteristics. Appliances covered by this document can be built-in or for placing on a working surface or the floor. For measurement of energy consumption and time for heating a load, this document is furthermore not applicable to: - microwave combination function; - ovens with reciprocating trays or turntable; - small cavity ovens; - 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 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). The standard differs from DIN EN 60350-1 (VDE 0705-350-1):2022-04 as follows: a) new definitions for heating function, eco function, and definitions relevant to low power consumption mode have been added to Clause 3; b) the order of the clauses has been changed; c) revision of 5.3; d) update of 6.2 to improve the reliability of volume measurement; e) deletion of 6.7, height of the shelf; f) revision of Clause 7 with regard to the accuracy of eco functions with residual heat utilization; g) revision of Clause 8 to improve the reliability of the energy consumption measurement procedure, in particular with regard to bypass protection; h) uniform energy consumption measurement for all heating functions and eco functions, specifying the energy consumption for a temperature increase of 165 K (instead of the current 155 K, for example for the recirculation function), resulting in higher energy consumption values compared to the previous edition; i) R<(Index)y replaced by L* in Clause 9 and reference to IEC TS 63350; j) cooking time for the reference measurement for broccoli added in Clause 10; k) yellow component replaced by hue angle value in Clause 10; l) requirements for digital evaluation (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 (operating mode with low power consumption, former Clause 12)); n) the former Annex G (informative) is deleted as this method for measuring a related activity has not been used; o) former Annexes B and F are obsolete; current color tables are specified in IEC TS 63350; p) former Annex E is replaced by an accompanying document available on the IEC website. Typical examples of applications of the document are ovens, stoves, grills, steam cookers, and combination steam cookers.
