Household and similar electrical appliances - Safety - Part 2-6: Particular requirements for stationary cooking ranges, hobs, ovens and similar appliances
IEC 60335-2-6:2024 deals with the safety of stationary electric cooking appliances, such as cooking ranges, hobs, and ovens, for household use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances.
This standard also includes some requirements for ovens that are intended to be used on board ships.
Examples of appliances that are within the scope of this standard are:
– griddles;
– grills;
– induction hobs;
– induction wok elements;
– pyrolytic self-cleaning ovens;
– steam ovens.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account:
– persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
This standard does not apply to:
– appliances intended for commercial catering;
– appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– grills, toasters and similar portable cooking appliances (IEC 60335-2-9);
– microwave ovens (IEC 60335-2-25).
This seventh edition cancels and replaces the sixth edition published in 2014 and Amendment 1:2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) alignment with IEC 60335-1:2020;
b) deletion of notes (15.2) and conversion of notes to normative text (Clause 1, 3.1.9.101, 7.103, 11.7, 15.2, 16.2, 22.109, 22.120, 22.132, 22.124, Figure 103);
c) application of test probe 19 (8.1.1, 20.2);
d) alignment of limits on the temperature rise of external accessible surfaces (Clause 11);
e) addition of requirements for automatic regulation systems and remote automatic regulation systems for induction hobs (3.7.103, 3.11.4, 3.11.5, 3.11.101, 7.12, 19.102, 22.40, 22.62, Annex AA);
f) addition of requirements for remote operation of ovens (22.51).
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.

Part 2-6: Particular requirements for stationary cooking ranges,
hobs, ovens and similar appliances
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 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 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.
This commented version (CMV) of the official standard IEC 60335-2-6:2024 edition 7.0
allows the user to identify the changes made to the previous IEC 60335-2-
6:2014+AMD1:2018 CSV edition 6.1. Furthermore, comments from IEC TC 61 experts are
provided to explain the reasons of the most relevant changes, or to clarify any part of the
content.
A vertical bar appears in the margin wherever a change has been made. Additions are in
green text, deletions are in strikethrough red text. Experts' comments are identified by a
blue-background number. Mouse over a number to display a pop-up note with the
comment.
This publication contains the CMV and the official standard. The full list of comments is
available at the end of the CMV.
IEC 60335-2-6 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This seventh edition cancels and replaces the sixth edition published in 2014 and
Amendment 1:2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) deletion of notes (15.2) and conversion of notes to normative text (Clause 1, 3.1.9.101,
7.103, 11.7, 15.2, 16.2, 22.109, 22.120, 22.132, 22.124, Figure 103);
c) application of test probe 19 (8.1.1, 20.2);
d) alignment of limits on the temperature rise of external accessible surfaces (Clause 11);
e) addition of requirements for automatic regulation systems and remote automatic regulation
systems for induction hobs (3.7.103, 3.11.4, 3.11.5, 3.11.101, 7.12, 19.102, 22.40, 22.62,
Annex AA);
f) addition of requirements for remote operation of ovens (22.51).

61/7253/FDIS 61/7275/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
A list of all parts of the IEC 60335 series, under the general title: Household and similar
electrical appliances – Safety, can be found on the IEC website.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
NOTE 1 When "Part 1" is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to convert
that publication into the IEC standard: Particular requirements for stationary cooking ranges,
hobs, ovens and similar appliances.

far as is reasonable. When this standard states "addition", "modification" or "replacement", the
relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;
– 6 – IEC 60335-2-6:2024 CMV © IEC 2024
– additional annexes are lettered AA, BB, etc.
NOTE 3 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or
• revised.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations can need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below.
– 11.101: Table 103 is applicable for limits on surface temperatures (Australia, New Zealand).
– 24.101: Socket-outlets have to be provided with residual current devices which may be
combined with the overcurrent protective device (Australia).
– 25.3: Cooking ranges that are not built-in shall not be permanently connected to the fixed
wiring (New Zealand).
IMPORTANT – The "colour inside" logo on the cover page of this document indicates

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules may can differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards Horizontal publications, basic safety publications and group safety
publications covering a hazard are not applicable since they have been taken into consideration when developing
the general and particular requirements for the IEC 60335 series of standards. For example, in the case of
temperature requirements for surfaces on many appliances, generic standards, such as ISO 13732-1 for hot surfaces,
are not applicable in addition to Part 1 or part 2 standards. 1
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with the
standard.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters. 2

3.1.9.101 Hob elements, other than induction hob elements and induction wok elements,
are operated with vessels containing cold water. The vessel is made of unpolished commercial
quality aluminium, has a flat bottom and is covered with a lid that is positioned so that steam
does not affect the tests. Thermal controls are adjusted to their highest setting until the water
boils and then adjusted so that the water boils gently. Water is added to maintain the level
during boiling.
In case of doubt, vessels as specified in Figure 101 are used.
Induction hob elements are operated with vessels as specified in Figure 102 that contain
cooking oil at room temperature. Thermal controls are adjusted to their highest setting until
the oil temperature reaches 180 °C ± 4 °C and then adjusted so that this temperature is
maintained. The oil temperature is measured 10 mm above the centre of the bottom of the
vessel.
Induction hob elements in a flexible induction cooking zone are operated with vessels
according to Figure 102 with diameters as specified in Figure 101 as follows:
a) the maximum number of vessels which can be separately controlled at the same time,
arranged to cover the flexible induction cooking zone as far as possible. Any combination
of vessels giving the most unfavourable results shall be used for the test. Several vessels
with the same diameter may be used;
b) the vessel which provides the highest power density (W/cm );
c) the smallest vessel that allows an induction hob element to operate.
Note 1 to entry: Vessels according to Figure 102 should be used for the tests. The vessel diameters specified in
Figure 101 should be considered for the tests.
Operation as specified in a), b) or c), that results in the most unfavourable condition for the
tests specified in the relevant subclauses is applied.
Induction wok elements are operated with a wok having an equivalent sphere diameter that
does not differ from the equivalent sphere diameter of the induction wok element cavity by
more than %. This wok may can be supplied by the manufacturer.

The wok is made of low carbon steel having a maximum carbon content of 0,08 % and a
thickness of 2 mm ± 0,5 mm. The height of the wok shall be approximately twice the depth of
the induction wok element cavity.
The wok is filled to approximately half of its height with cooking oil at room temperature.
Thermal controls are adjusted to their highest setting until the oil temperature reaches
180 °C ± 4 °C and then adjusted so that this temperature is maintained. The oil temperature is
measured 10 mm above the centre of the bottom of the vessel.
For all hob elements other than those in a flexible induction cooking zone and induction
wok elements, the diameter of the bottom of the vessel is approximately equal to the diameter
of the cooking zone and the quantity of liquid is specified in Table 101. The vessel is positioned
centrally on the cooking zone.
If several cooking zones are marked for one hob element, the most unfavourable cooking
zone is used for the test.
For non-circular cooking zones, the smallest non-circular vessel is used which will cover the
cooking zone as far as possible, taking into account the hob rim and the other vessels. The
quantity of liquid is determined on the basis of the minor diameter of the cooking zone.

Thermal controls are adjusted so that the mean temperature in the centre of the oven is
maintained at
– 220 °C ± 4 °C for ovens with forced air circulation;
– 240 °C ± 4 °C for other ovens.
If the temperature cannot be attained, the thermal control is adjusted to its highest setting.
Ovens without thermal controls are switched on and off so that the temperature in the centre
of the oven is maintained at 240 °C ± 15 °C.
Atmospheric steam ovens and pressure steam ovens are operated in accordance with the
instructions. Lids, doors and covers are in position and closed. Controls are adjusted to their
highest setting until the cooking temperature is reached and then adjusted to the lowest setting
that maintains this temperature.
Steam generators intended to be filled by hand are filled according to the instructions, water
being added to maintain the steam generation.
Steam generators intended to be filled automatically are connected to a water supply, the
pressure of which is set according to the instructions.

controls adjusted as for operation without steam.
3.1.9.103 Grills are operated empty with the grill pan and food supports in the most
unfavourable position for normal use, the door and any other accessories being positioned in
accordance with the instructions. In the absence of such instructions, the door and other
accessories are placed in the most unfavourable position in which they may can be left. Thermal
controls are adjusted to their highest setting. However, if the instructions for grills incorporated
in ovens specify a lower setting, this setting is used. Any reflectors intended to be placed above
heating elements are in position.
3.1.9.104 Rotating spits in ovens or grills are operated with the load on the rotating spit as
shown in Figure 103. The load is positioned on the rotary spit so that the fixing screw contacts
the diameter of the spit 6. The appliance is operated taking into account the instructions with
regard to:

INTRODUCTION
Edition 6 of IEC 60335-1:2020 defines and introduces requirements for a detachable
power supply part of an appliance. In the document, 24.2 prohibits the use of a power
supply in a flexible cord.
QUESTION:
Does Subclause 24.2 prohibit the use of a detachable power supply part?
ANSWER
No, a "detachable power supply part" is a defined term and is not captured by the term
"power supply" as used in Subclause 24.2.
NOTE A detachable power supply part is captured by the defined term when the output of the power supply
part is detachable from the class III construction part of the appliance at:
– the power supply part, or
– the class III construction part of the appliance.
However, the supply cord (if any) does not have to be detachable from the detachable power supply part.

Part 2-6: Particular requirements for stationary cooking ranges,
hobs, ovens and similar appliances
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

INTRODUCTION to IEC 60335-1:2020
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website –
www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules may differ.
If the functions of an appliance are covered by different parts 2 of IEC 60335, the relevant part 2
is applied to each function separately, as far as is reasonable. If applicable, the influence of
one function on the other is taken into account.
Throughout this publication, when "part 2" is mentioned, it refers to the relevant part of
IEC 60335.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal publications, basic safety publications and group safety publications covering a hazard are not
applicable since they have been taken into consideration when developing the general and particular requirements
for the IEC 60335 series of standards.
Individual countries may wish to consider the application of this standard, as far as is
reasonable, to appliances not mentioned in a part 2, and to appliances designed on new
principles. In this case, consideration should be given to defining normal operation, specifying
the classification of the appliance according to Clause 6 and specifying whether the appliance
is operated attended or unattended. Consideration should also be given to particular categories
of likely users and to related specific risks such as access to live parts, hot surfaces or
hazardous moving parts.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of this standard if, when examined and tested, it is found to
have other features which impair the level of safety covered by these requirements.
– 10 – IEC 60335-2-6:2024 EXV © IEC 2024
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with this
standard.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

Part 2-6: Particular requirements for stationary cooking ranges,
hobs, ovens and similar appliances
1 Scope
This Part of IEC 60335 deals with the safety of stationary electric cooking appliances, such
as cooking ranges, hobs, and ovens, for household use, their rated voltage being not more
than 250 V for single-phase appliances connected between one phase and neutral, and 480 V
for other appliances including direct current (DC) supplied appliances and battery-operated
appliances.
This standard also includes some requirements for ovens that are intended to be used on board
ships.
Examples of appliances that are within the scope of this standard are:
– griddles;
– grills;
– induction hobs;
– induction wok elements;
– pyrolytic self-cleaning ovens;
– steam ovens.
As far as is practicable, this standard deals with the common hazards presented by appliances
that are encountered by all persons in and around the home. However, in general, it does not
take into account:
– persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities,
the national authorities responsible for the protection of labour, the national water supply
authorities and similar authorities.
This standard does not apply to:
– appliances intended for commercial catering;
– appliances intended to be used in locations where special conditions prevail, such as the
presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– grills, toasters and similar portable cooking appliances (IEC 60335-2-9);
– microwave ovens (IEC 60335-2-25).

Part 2-6: Particular requirements for stationary cooking ranges,
hobs, ovens and similar appliances
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 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 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 60335-2-6 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This seventh edition cancels and replaces the sixth edition published in 2014 and
Amendment 1:2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) deletion of notes (15.2) and conversion of notes to normative text (Clause 1, 3.1.9.101,
7.103, 11.7, 15.2, 16.2, 22.109, 22.120, 22.132, 22.124, Figure 103);
c) application of test probe 19 (8.1.1, 20.2);
d) alignment of limits on the temperature rise of external accessible surfaces (Clause 11);
e) addition of requirements for automatic regulation systems and remote automatic regulation
systems for induction hobs (3.7.103, 3.11.4, 3.11.5, 3.11.101, 7.12, 19.102, 22.40, 22.62,
Annex AA);
f) addition of requirements for remote operation of ovens (22.51).
The text of this International Standard is based on the following documents:

organizations can need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below.
– 11.101: Table 103 is applicable for limits on surface temperatures (Australia, New Zealand).
– 24.101: Socket-outlets have to be provided with residual current devices which may be
combined with the overcurrent protective device (Australia).
– 25.3: Cooking ranges that are not built-in shall not be permanently connected to the fixed
wiring (New Zealand).

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules can differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal publications, basic safety publications and group safety publications covering a hazard are not
applicable since they have been taken into consideration when developing the general and particular requirements
for the IEC 60335 series of standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with the
standard.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

SAFETY –
Part 2-6: Particular requirements for stationary cooking ranges,
hobs, ovens and similar appliances
1 Scope
This clause of Part 1 is replaced by the following.
This Part of IEC 60335 deals with the safety of stationary electric cooking appliances, such
as cooking ranges, hobs, and ovens, for household use, their rated voltage being not more
than 250 V for single-phase appliances connected between one phase and neutral, and 480 V
for other appliances including direct current (DC) supplied appliances and battery-operated
appliances.
This standard also includes some requirements for ovens that are intended to be used on board
ships.
Examples of appliances that are within the scope of this standard are:
– griddles;
– grills;
– induction hobs;
– induction wok elements;
– pyrolytic self-cleaning ovens;
– steam ovens.
As far as is practicable, this standard deals with the common hazards presented by appliances
that are encountered by all persons in and around the home. However, in general, it does not
take into account:
– persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities,
the national authorities responsible for the protection of labour, the national water supply
authorities and similar authorities.
This standard does not apply to:
– appliances intended for commercial catering;
– appliances intended to be used in locations where special conditions prevail, such as the
presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– grills, toasters and similar portable cooking appliances (IEC 60335-2-9);
– microwave ovens (IEC 60335-2-25).

3.1.9.101 Hob elements, other than induction hob elements and induction wok elements,
are operated with vessels containing cold water. The vessel is made of unpolished commercial
quality aluminium, has a flat bottom and is covered with a lid that is positioned so that steam
does not affect the tests. Thermal controls are adjusted to their highest setting until the water
boils and then adjusted so that the water boils gently. Water is added to maintain the level
during boiling.
In case of doubt, vessels as specified in Figure 101 are used.
Induction hob elements are operated with vessels as specified in Figure 102 that contain
cooking oil at room temperature. Thermal controls are adjusted to their highest setting until
the oil temperature reaches 180 °C ± 4 °C and then adjusted so that this temperature is
maintained. The oil temperature is measured 10 mm above the centre of the bottom of the
vessel.
Induction hob elements in a flexible induction cooking zone are operated with vessels
according to Figure 102 with diameters as specified in Figure 101 as follows:
a) the maximum number of vessels which can be separately controlled at the same time,
arranged to cover the flexible induction cooking zone as far as possible. Any combination
of vessels giving the most unfavourable results shall be used for the test. Several vessels
with the same diameter may be used;
b) the vessel which provides the highest power density (W/cm );
c) the smallest vessel that allows an induction hob element to operate.
Operation as specified in a), b) or c), that results in the most unfavourable condition for the
tests specified in the relevant subclauses is applied.
Induction wok elements are operated with a wok having an equivalent sphere diameter that
does not differ from the equivalent sphere diameter of the induction wok element cavity by
more than %. This wok can be supplied by the manufacturer.
− 1
The wok is made of low carbon steel having a maximum carbon content of 0,08 % and a
thickness of 2 mm ± 0,5 mm. The height of the wok shall be approximately twice the depth of
the induction wok element cavity.
The wok is filled to approximately half of its height with cooking oil at room temperature.
Thermal controls are adjusted to their highest setting until the oil temperature reaches
180 °C ± 4 °C and then adjusted so that this temperature is maintained. The oil temperature is
measured 10 mm above the centre of the bottom of the vessel.
For all hob elements other than those in a flexible induction cooking zone and induction
wok elements, the diameter of the bottom of the vessel is approximately equal to the diameter
of the cooking zone and the quantity of liquid is specified in Table 101. The vessel is positioned
centrally on the cooking zone.
If several cooking zones are marked for one hob element, the most unfavourable cooking
zone is used for the test.
For non-circular cooking zones, the smallest non-circular vessel is used which will cover the
cooking zone as far as possible, taking into account the hob rim and the other vessels. The
quantity of liquid is determined on the basis of the minor diameter of the cooking zone.

3.1.9.102 Ovens and steam convection ovens are operated empty with the door closed.
Thermal controls are adjusted so that the mean temperature in the centre of the oven is
maintained at
– 220 °C ± 4 °C for ovens with forced air circulation;
– 240 °C ± 4 °C for other ovens.
If the temperature cannot be attained, the thermal control is adjusted to its highest setting.
Ovens without thermal controls are switched on and off so that the temperature in the centre
of the oven is maintained at 240 °C ± 15 °C.
Atmospheric steam ovens and pressure steam ovens are operated in accordance with the
instructions. Lids, doors and covers are in position and closed. Controls are adjusted to their
highest setting until the cooking temperature is reached and then adjusted to the lowest setting
that maintains this temperature.
Steam generators intended to be filled by hand are filled according to the instructions, water
being added to maintain the steam generation.
Steam generators intended to be filled automatically are connected to a water supply, the
pressure of which is set according to the instructions.
The supply water has a temperature of
– 15 °C ± 5 °C for appliances to be connected to a cold water supply;
– 60 °C ± 5 °C or the temperature indicated in the instructions, whichever is the higher, for
appliances to be connected to a hot water supply.
Steam convection ovens are also operated while generating steam but with the thermal
controls adjusted as for operation without steam.
3.1.9.103 Grills are operated empty with the grill pan and food supports in the most
unfavourable position for normal use, the door and any other accessories being positioned in
accordance with the instructions. In the absence of such instructions, the door and other
accessories are placed in the most unfavourable position in which they can be left. Thermal
controls are adjusted to their highest setting. However, if the instructions for grills incorporated
in ovens specify a lower setting, this setting is used. Any reflectors intended to be placed above
heating elements are in position.
3.1.9.104 Rotating spits in ovens or grills are operated with the load on the rotating spit as
shown in Figure 103. The load is positioned on the rotary spit so that the fixing screw contacts
the diameter of the spit. The appliance is operated taking into account the instructions with
regard to:
– the heating elements to be operated;
– the setting of the thermal control;
– the position of the door and grill pan.
