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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

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.
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.
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 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.
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.
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.

operation of the appliance under the following conditions
Solid hob elements are operated with no load and sheathed hob elements are operated with
a load made of dull black, cold or hot rolled steel, 9 mm to 10 mm thick, that covers not less
than 90 % and not more than 100 % of the element surface. The hob elements are operated
with the controls set to give the temperatures as set out below, the temperature being
measured at the geometrical centre or the hottest point of the solid element or load, if the
element is unevenly heated.
Stepped controls are set to the first position that gives a temperature equal to or greater
than 275 °C. Cycling controls are set so that the mean value of the temperature over the cycle
is 275 °C ± 5 °C. If this temperature cannot be reached, the control is set at the maximum.
Non-induction heating sources beneath a glass-ceramic or similar material are operated with
a pan or pans containing initially cold water, the pan(s) being filled to a height of
60 mm ± 10 mm. The pan or pans are of aluminium, of ordinary quality, not brightly polished,
with a base concavity not exceeding 0,1 mm. The pan or pans shall cover the cooking zone
to the greatest extent possible.
The pan or pans are covered with a lid. The controls are set at maximum until the water boils
and then adjusted to maintain boiling. Water is added to maintain the water level during
boiling.
Induction heating sources beneath a glass-ceramic or similar material are operated with the
pan or pans recommended by the manufacturer.
If one pan is used, it shall cover as closely as possible, but not less than, the full area of the
cooking zone. The pan is positioned centrally.
For non-circular cooking zones a combination of the smallest number of pans is chosen to
cover as much as possible the area of the cooking zone.
The pan or pans in each case are filled with initially cold frying oil to a height of
30 mm ± 5 mm. The controls are set to maximum until the temperature of the oil attains a
value of 180 °C and then adjusted to maintain the oil at a temperature of 180 °C ± 15 °C.
A further test is made using initially cold water, the pan(s) being filled to a height of
60 mm ± 10 mm. The pan or pans are covered with a lid. The controls are set at maximum
until the water boils and then adjusted to maintain boiling. Water is added to maintain the
water level during boiling.
The condition providing the most unfavourable results (oil or water) is used.
Ovens are operated with no load and with the controls set so that the mean value of the
temperature over the thermostat cycle at the geometric centre of the usable space in the
interior of the oven is maintained at 240 °C ± 4 °C. Stepped controls are set so that this
temperature is 240 °C ± 15 °C. For ovens that are capable of attaining temperatures in excess
of 290 °C, the controls are set so that the temperature is 50 °C ± 4 °C below the maximum
temperature attainable. For ovens that are unable to attain a temperature of 240 °C, the
controls are set to maximum.
Griddle plates are operated with no load and with the controls set so as to give the
temperatures set out below, the temperature being measured at the hottest point of each
controlled cooking surface. Stepped controls are set to the first position that gives a
temperature equal to or greater than 275 °C. Cycling controls are set so that the mean value
of the temperature over the cycle is 275 °C ± 5 °C. If this temperature cannot be reached, the
control is set to maximum.
Motors incorporated in the appliance are operated in the intended manner under the most
severe conditions that can be expected in normal use, taking into account the manufacturer's
instructions.

measurement is made before the controls are adjusted to the reduced setting.
The power inputs so measured shall in the case of the induction heating sources not
deviate from the power input marked or declared by the manufacturer (see 7.1) by more than
10 %, and in the case of the non-induction heating sources not deviate from the power input
marked or declared by the manufacturer (see 7.1) by more than that given in Table 1 for
heating appliances.
In addition, the power input of the appliance when the induction and non-induction heating sources
are operated simultaneously shall not deviate from the rated power input by more than 10 %.
Addition:
NOTE 101 For appliances having more than one heating unit, the total power input may be determined by
measuring the power input of each heating unit separately (see also 3.1.4).

– 14 – 60335-2-36 © IEC:2002+A1:2004(E)
11 Heating
This clause of Part 1 is applicable except as follows.
11.2 Addition:
Appliances intended to be fixed to the floor and appliances with a mass greater than 40 kg
and not provided with rollers, castors or similar means are installed in accordance with the
manufacturer's instructions. If no instructions are given, these appliances are considered as
appliances normally placed on the floor.
11.3 Addition:
NOTE 101 If the measurements can be unduly influenced by emissions from an induction heating source,
i.e. the magnetic field, this must be taken into account.
In general, the use of thermocouples is not recommended because of the expected faulty heating-up of the
thermocouples caused by the induction heating source. For example, the temperature rise of the induction
heating source can be determined by using a platinum resistance, preferably of high resistance, with twisted
connecting wires. The platinum resistances are placed on the hottest point of the winding so as to influence as little
as possible the temperature to be measured.
11.4 Replacement:
The non-induction heating units of the appliance are operated under normal operation at
1,15 times the power input marked or declared (see 7.1).
If the temperature rise limits of motors, transformers or electronic circuits are exceeded, the
test is repeated with the appliance supplied at 1,06 times rated voltage. In this case, only the
temperature rises of motors, transformers and electronic circuits are measured.
Induction heating units are operated simultaneously and supplied separately at the most
unfavourable voltage between 0,94 times minimum rated voltage and 1,06 times maximum
rated voltage.
If it is not possible to switch on all heating elements or induction heating sources at the
same time, the test is made with each of the combinations that the switch arrangement will
allow, the highest load possible with each switching arrangement being in circuit.
If the appliance is provided with a control that limits the total power input, the test is made
with whichever combination of heating units, as may be selected by the control, imposes
the severest condition.
In addition, appliances incorporating induction heating sources are also operated as
above, but with the smallest size of pan as recommended by the manufacturer placed in the
most onerous position consistent with being able to energize the coil, but within the
cooking zone.
NOTE 101 The additional operating condition described above is not applied when reference to Clause 11 is
made in other tests.
11.7 Replacement:
Appliances are operated until steady conditions are established.
NOTE 101 The duration of the test may consist of more than one cycle of operation.

60335-2-36 © IEC:2002+A1:2004(E) – 15 –
11.8 Addition:
The limit of 65 K temperature rise for the rear and side test walls, including the part of the
test corner that projects in front of the appliance, only applies below the level of the hob
surface. If this temperature rise limit is exceeded above the hob surface then the
requirements of 7.101 apply.
12 Void
13 Leakage current and electric strength at operating temperature
This clause of Part 1 is applicable except as follows.
13.1 Modification:
Instead of the first four paragraphs of the test specification the following applies.
Compliance is checked by the tests of 13.2 and 13.3, which are made after the appliance has
been operated under the conditions specified in Clause 11. The appliance is operated until
the leakage current has reached a steady value or for the time specified in 11.7, whichever is
the shorter period.
If more than one pan is placed on a single cooking zone, they are electrically connected
together.
13.2 Modification:
Instead of the permissible leakage current for stationary class I appliances, the following
applies:
– for cord and plug connected appliances 1 mA per kW rated power input of the
appliance with a maximum of 10 mA
– for other appliances 1 mA per kW rated power input of the
appliance with no maximum
13.3 Addition:
If there is earthed metal between live parts and the surface of glass-ceramic or similar
material, all the pans on the hob surface are electrically connected together and to earthed
metal.
A test voltage of 1 000 V is then applied between live parts and the pans.
If there is no earthed metal between live parts and the surface of glass-ceramic or similar
material, all the pans on the hob surface are electrically connected together, but not
connected to earthed metal.
A test voltage of 3 000 V is then applied between live parts and the pans.
NOTE 101 Care is taken to ensure that the voltage applied does not overstress the other insulations.
14 Transient overvoltages
This clause of Part 1 is applicable.

– 16 – 60335-2-36 © IEC:2002+A1:2004(E)
15 Moisture resistance
This clause of Part 1 is applicable except as follows.
15.1.1 Addition:
In addition, IPX0, IPX1, IPX2, IPX3 and IPX4 appliances are subjected for 5 min to the
following splash test.
The apparatus shown in Figure 101 is used. During the test, the water pressure is so
regulated that the water splashes up 150 mm above the bottom of the bowl. The bowl is
placed on the floor for appliances normally used on the floor. For all other appliances on a
horizontal support 50 mm below the lowest edge of the appliance, the bowl is moved around
in such a way as to splash the appliance from all directions. Care is taken that the appliance
is not hit by the direct jet.
15.1.2 Modification:
Appliances normally used on a table are placed on a support having dimensions that are
15 cm ± 5 cm in excess of those of the orthogonal projection of the appliance on the support.
Addition:
If detailed instructions regarding the cleaning of movable but non-detachable (for example
hinged) hob elements are given in the instruction sheet, tests on these hob elements are
carried out with the elements in the horizontal position of normal use.
15.2 Replacement:
Appliances shall be constructed so that spillage of liquid in normal use does not affect their
electrical insulation.
Compliance is checked by the following test.
Appliances with type X attachment, except those having a specially prepared cord, are fitted
with the lightest permissible type of flexible cable or cord of the smallest cross-sectional area
specified in 26.6 and other appliances are tested as delivered.
Detachable parts are removed.
Appliances are positioned so that the hob surface is horizontal and if the hob elements are
adjustable separately, their surfaces are also horizontal.
A vessel having a diameter equal to or not more than 25 mm smaller than the largest
inscribed circle on the hob element or cooking zone is completely filled with cold salt water
and placed in the most unfavourable position, not overlapping the hob element or the
cooking zone.
A further quantity of cold salt water equal to approximately 2 l is poured steadily into the
vessel over a period of 1 min.
NOTE 101 The test is made on each hob element

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by IEC subcommittee 61E:
Safety of electrical commercial catering equipment, of IEC technical committee 61: Safety of
household and similar electrical appliances.
This fifth edition of IEC 60335-2-36 cancels and replaces the fourth edition published in
2000. It constitutes a technical revision.

INTRODUCTION
Il a été considéré en établissant la présente Norme internationale que l'exécution de ses
dispositions était confiée à des personnes expérimentées et ayant une qualification
appropriée.
Cette norme reconnaît le niveau de protection internationalement accepté contre les risques
électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils, lorsqu'ils
fonctionnent comme en usage normal en tenant compte des instructions du fabricant. Elle
couvre également les situations anormales auxquelles on peut s'attendre dans la pratique.
Cette norme tient compte autant que possible des exigences de la CEI 60364, de façon à
rester compatible avec les règles d'installation quand l’appareil est raccordé au réseau
d’alimentation. Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil compris dans le domaine d’application de cette norme comporte également des
fonctions qui sont couvertes par une autre partie 2 de la CEI 60335, la partie 2 corres-
pondante est appliquée à chaque fonction séparément, dans la limite du raisonnable. Si cela
est applicable, on tient compte de l’influence d’une fonction sur les autres fonctions.
Cette norme est une norme de famille de produits traitant de la sécurité d’appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé
conforme aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais,
il apparaît qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité
visé par ces exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de
ceux décrits dans les exigences de cette norme peut être examiné et essayé en fonction de
l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut être
estimé conforme aux principes de sécurité de la norme.

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.
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.
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 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.
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.
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.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

This part of International Standard IEC 60335 has been prepared by IEC subcommittee 61E:
Safety of electrical commercial catering equipment, of IEC technical committee 61: Safety of
household and similar electrical appliances.
This consolidated version of IEC 60335-2-36 consists of the fifth edition (2002) [documents

INTRODUCTION
Il a été considéré en établissant la présente Norme internationale que l'exécution de ses

dispositions était confiée à des personnes expérimentées et ayant une qualification

appropriée.
Cette norme reconnaît le niveau de protection internationalement accepté contre les risques

électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils, lorsqu'ils

fonctionnent comme en usage normal en tenant compte des instructions du fabricant. Elle

couvre également les situations anormales auxquelles on peut s'attendre dans la pratique.

Cette norme tient compte autant que possible des exigences de la CEI 60364, de façon à
rester compatible avec les règles d'installation quand l’appareil est raccordé au réseau
d’alimentation. Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil compris dans le domaine d’application de cette norme comporte également des
fonctions qui sont couvertes par une autre partie 2 de la CEI 60335, la partie 2 corres-
pondante est appliquée à chaque fonction séparément, dans la limite du raisonnable. Si cela
est applicable, on tient compte de l’influence d’une fonction sur les autres fonctions.
Cette norme est une norme de famille de produits traitant de la sécurité d’appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé
conforme aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais,
il apparaît qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité
visé par ces exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de
ceux décrits dans les exigences de cette norme peut être examiné et essayé en fonction de
l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut être
estimé conforme aux principes de sécurité de la norme.

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.

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.

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 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.
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.
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.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by IEC subcommittee 61E:
Safety of electrical commercial catering equipment, of IEC technical committee 61: Safety of
household and similar electrical appliances.
This consolidated version of IEC 60335-2-36 consists of the fifth edition (2002) [documents
61E/398/FDIS and 61E/410/RVD], its amendment 1 (2004) [documents 61E/435/FDIS and
61E/437/RVD] and its amendment 2 (2008) [documents 61E/594/FDIS and 61E/609/RVD].
The technical content is therefore identical to the base edition and its amendments and has
been prepared for user convenience.
It bears the edition number 5.2.
A vertical line in the margin shows where the base publication has been modified by
amendments 1 and 2.

The French version of this standard has not been voted upon.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fourth edition (2001) 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: Safety requirements for commercial electric
cooking ranges, ovens, hobs and hob elements.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as 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;
– additional annexes are lettered AA, BB, etc.
NOTE 3 The following print types are used:
– requirements: in roman type;

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.
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 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 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.
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.

such an object.
Compliance is checked by inserting test probe 12 of IEC 61032 at all points where the probe
can enter in the vicinity of live parts. The probe is applied without appreciable force.
9 Starting of motor-operated appliances
This clause of Part 1 is applicable except as follows.
9.101 Fan motors providing a cooling effect in order to comply with the requirements of
Clause 11 shall start under all voltage conditions that may occur in use.
Compliance is checked by starting the motor three times at a voltage equal to 0,85 times
rated voltage, the motor being at room temperature at the beginning of the test.
The motor is started each time under the conditions occurring at the beginning of normal
operation or, for automatic appliances, at the beginning of the normal cycle of operation, the
motor being allowed to come to rest between successive starts. For appliances provided with
motors having other than centrifugal starting switches, this test is repeated at a voltage equal
to 1,06 times rated voltage.
In all cases, the motor shall start and it shall function in such a way that safety is not affected
and overload protection devices of the motor shall not operate.
NOTE The supply source must be such that during the test the drop in voltage does not exceed 1 %.
10 Power input and current
This clause of Part 1 is applicable except as follows.
10.1 Modification:
Instead of the first paragraph of the requirement, the following applies.

– 14 – 60335-2-36 © IEC:2002+A1:2004
+A2:2008
The power input of appliances without induction heating sources, at rated voltage and at
normal operating temperature, shall not deviate from the rated power input by more than the
deviation shown in Table 1.
The power input of appliances having only induction heating sources, at rated voltage and
at normal operating temperature, shall not deviate from the rated power input by more than
10 %.
The measurement is made before the controls are adjusted to the reduced setting.
For appliances incorporating induction and non-induction heating sources the following
applies.
The power input of the induction heating sources and the non-induction heating sources is
measured separately, in each case using a combination of heating units that can be on at
the same time to give the highest power input. For the induction heating sources, the
measurement is made before the controls are adjusted to the reduced setting.
The power inputs so measured shall in the case of the induction heating sources not
deviate from the power input marked or declared by the manufacturer (see 7.1) by more than
10 %, and in the case of the non-induction heating sources not deviate from the power input
marked or declared by the manufacturer (see 7.1) by more than that given in Table 1 for
heating appliances.
In addition, the power input of the appliance when the induction and non-induction heating
sources are operated simultaneously shall not deviate from the rated power input by more
than 10 %.
Addition:
NOTE 101 For appliances having more than one heating unit, the total power input may be determined by
measuring the power input of each heating unit separately (see also 3.1.4).
11 Heating
This clause of Part 1 is applicable except as follows.
11.2 Addition:
Appliances intended to be fixed to the floor and appliances with a mass greater than 40 kg
and not provided with rollers, castors or similar means are installed in accordance with the
manufacturer's instructions. If no instructions are given, these appliances are considered as
appliances normally placed on the floor.
11.3 Addition:
NOTE 101 If the measurements can be unduly influenced by emissions from an induction heating source,
i.e. the magnetic field, this must be taken into account.
In general, the use of thermocouples is not recommended because of the expected faulty heating-up of the
thermocouples caused by the induction heating source. For example, the temperature rise of the induction
heating source can be determined by using a platinum resistance, preferably of high resistance, with twisted
connecting wires. The platinum resistances are placed on the hottest point of the winding so as to influence as little
as possible the temperature to be measured.

60335-2-36 © IEC:2002+A1:2004 – 15 –
+A2:2008
11.4 Replacement:
The non-induction heating units of the appliance are operated under normal operation at
1,15 times the power input marked or declared (see 7.1).
If the temperature rise limits of motors, transformers or electronic circuits are exceeded, the
test is repeated with the appliance supplied at 1,06 times rated voltage. In this case, only the
temperature rises of motors, transformers and electronic circuits are measured.
Induction heating units are operated simultaneously and supplied separately at the most
unfavourable voltage between 0,94 times minimum rated voltage and 1,06 times maximum
rated voltage.
If it is not possible to switch on all heating elements or induction heating sources at the
same time, the test is made with each of the combinations that the switch arrangement will
allow, the highest load possible with each switching arrangement being in circuit.
If the appliance is provided with a control that limits the total power input, the test is made
with whichever combination of heating units, as may be selected by the control, imposes
the severest condition.
In addition, appliances incorporating induction heating sources are also operated as
above, but with the smallest size of pan as recommended by the manufacturer placed in the
most onerous position consistent with being able to energize the coil, but within the
cooking zone.
NOTE 101 The additional operating condition described above is not applied when reference to Clause 11 is
made in other tests.
11.7 Replacement:
Appliances are operated until steady conditions are established.
NOTE 101 The duration of the test may consist
