IEC 60350-2:2025 defines methods for measuring the performance of electric hobs for household use. Appliances covered by this document can be built-in or designed to be placed on a work surface. The hob can be part of a cooking range and it can have an integrated cooking fume extractor, i.e. a hob with down-draft system . This document defines the main performance characteristics of hobs which are of interest to the user and specifies methods for measuring these characteristics. This document does not specify a classification or ranking for performance. Some of the tests which are specified in this document are not considered to be reproducible since the results can vary between laboratories. They are therefore intended for comparative testing purposes only. This document does not deal with safety requirements (IEC 60335-2-6 and IEC 60335-2-9). This document is also applicable for portable appliances with similar functionality. This third edition cancels and replaces the second edition published in 2017 and Amendment 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 portable hob, hob with down-draft system and low power modes are amended in Clause 3;
b) revision of Clause 5: Tolerance for water amount added, requirements for dimension measurement added;
c) removal of 6.4 Level of solid hotplates;
d) revision of Clause 7 in order to improve the application of the smoothing average;
e) revision of Table 1 and Table 3 in order to amend missing tolerances:
f) Ry replaced by L* in Clause 9 and reference to IEC TS 63350;
g) requirements for digital assessment in 9.1.6 removed as they are covered in IEC TS 63350;
h) revision of Clause 12 Power measurement of low power modes;
i) removal of Clause 13 Spillage capacity of hobs;
j) Annex G Low-power mode measurements added;
k) removal of Annex D 'Shade chart' as the shade charts are specified in IEC TS 63350;
l) removal of Annex E 'Data and calculation sheet' as the calculation sheet is substituted by a
supporting document located on the IEC web site;
m) update of former Annex F 'Addresses of suppliers' by removal of former Clause F.6, F.7 and F.8 and by adding a further possible supplier in new D.4
