INTERNATIONAL ELECTROTECHNICAL COMMISSION
____________
Household electric cooking appliances -
Part 2: Hobs - Methods for measuring performance

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for
standardization comprising all national electrotechnical committees (IEC National Committees).
The object of IEC is to promote international co-operation on all questions concerning
standardization in the electrical and electronic fields. To this end and in addition to other
activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National
Committee interested in the subject dealt with may participate in this preparatory work.
International, governmental and non-governmental organizations liaising with the IEC also
participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as
possible, an international consensus of opinion on the relevant subjects since each technical
committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted
by IEC National Committees in that sense. While all reasonable efforts are made to ensure that
the technical content of IEC Publications is accurate, IEC cannot be held responsible for the
way in which they are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC
Publications transparently to the maximum extent possible in their national and regional
publications. Any divergence between any IEC Publication and the corresponding national or
regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies
provide conformity assessment services and, in some areas, access to IEC marks of conformity.
IEC is not responsible for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including
individual experts and members of its technical committees and IEC National Committees for
any personal injury, property damage or other damage of any nature whatsoever, whether direct
or indirect, or for costs (including legal fees) and expenses arising out of the publication, use
of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced
publications is indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve
the use of (a) patent(s). IEC takes no position concerning the evidence, validity or applicability
of any claimed patent rights in respect thereof. As of the date of publication of this document,
IEC had not received notice of (a) patent(s), which may be required to implement this document.
However, implementers are cautioned that this may not represent the latest information, which
IEC 60350-2:2025 © IEC 2025
may be obtained from the patent database available at https://patents.iec.ch. IEC shall not be
held responsible for identifying any or all such patent rights.
IEC 60350-2 has been prepared by subcommittee 59K: Performance of household and similar
electrical cooking appliances, of IEC technical committee TC 59: Performance of household
and similar electrical appliances. It is an International Standard.
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 (3.24), hob with down-draft system (3.23) 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 (3.5);
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.
The text of this International Standard is based on the following documents:

there is more than one control (3.11).
3.11
control
part of the hob (3.2) for adjusting the power or temperature respectively of a cooking zone (3.3)
or a cooking area with limitative marking (3.10) or a cooking area without limitative marking
(3.9) for one piece of cookware, independent from technical solution (e.g. knobs, touch controls,
etc.)
Note 1 to entry: The power is generally indicated as numbers, but also temperature values and symbols are
possible.
Note 2 to entry: Controls (3.11) integrated outside of the hob (3.2) in a separate device or as part of a built-in-oven
are also included.
3.12
warming zone
area used for keeping food warm usually not used for cooking
Note 1 to entry: Normally one power setting exists - on and off.

3.14
standardized cookware
cookware that is in accordance with the specification of 5.6.1
3.15
alternative cookware
commercially available cookware that is in accordance with the requirements given in 5.6.2
3.16
active mode
mode in which the appliance is connected to the mains power source, has been activated, and
is performing any of the intended functions
Note 1 to entry: Examples of recognised associated functions are displaying recipes, running an egg timer, software
download, running a cooling fan, residual heat indication.
[SOURCE: IEC 60350-1:2023 [3], 3.1, modified - The example has been deleted, in the Note to
entry "and the like" has been replaced with "residual heat indication".]
3.17
network
communication infrastructure with a topology of links, an architecture, including the physical
components, organizational principles, communication procedures and formats (protocols)

3.18
open loop control
mode of operation in which the value of the power output is set at a desired value, without
taking into account the difference between the actual and desired values
EXAMPLE A cooking zone (3.3) with an electronic, electromechanical, or mechanical control (3.11) of the power
input, which is controlled independently of the actual temperature in the cookware.
[SOURCE: IEC 60050-300:2001 [5], 314-05-02, modified - In the term itself, "stabilization" has
been replaced by "control"; in the definition, "output" has been replaced by "power output", the
words "by external means" have been removed and the example has been added.]
3.19
closed loop control
mode of operation in which the value of the output is influenced by comparing of a reference
value by the measured value and using the difference between those values, directly or
indirectly, to maintain the output quantity at the desired value with a given uncertainty
EXAMPLE The value can be a measured temperature at the cookware or under the glass ceramic.
[SOURCE: IEC 60050-300:2001 [5], 314-05-01, modified - In the term itself, "stabilization" has
been replaced by "control"; in the definition, "is compared with a reference value and in which
the difference between those values is used" is replaced by "is influenced by comparing of a
reference value by the measured value and using the difference between those values" and the
example has been added.]
3.20
off mode
condition in which the appliance is connected to the mains and is not providing any active mode
(3.16) or standby mode (3.21) and where the mode can persist for an indefinite time
Note 1 to entry: The following shall also be considered as off mode (3.20):
a) conditions providing only an indication of off mode (3.20);
IEC 60350-2:2025 © IEC 2025
b) conditions providing only functionalities intended to ensure electromagnetic compatibility.
[SOURCE: IEC 60350-1:2023 [3], 3.12]
3.21
standby mode
condition where the appliance is connected to the mains and provides only the following
functions, which can persist for an indefinite duration:
a) reactivation function, or reactivation function and a mere indication of enabled reactivation
function;
b) information or status display;
c) protective function.
EXAMPLE 1 An example for the protective function is an acoustical signal when touch controls are overflowed with
water.
EXAMPLE 2 An example for the reactivation function is an internal touch control (3.11) sensor, which continuously
monitors any user’s interaction.
[SOURCE: IEC 60350-1:2023 [3], 3.17, modified - In the definition, item c), "detection function
for emergency measures” has been replaced by “protective function" and examples have been
added.]
