Part 2-38: Particular requirements

for commercial electric griddles and griddle grills

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The 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 cancels and replaces the fourth edition published in 2000. It constitutes a
technical revision.
The text of this part of IEC 60335 is based on the following documents:

FDIS Report on voting
61E/400/FDIS 61E/412 /RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
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
griddles and griddle grills.
– 4 – 60335-2-38 © IEC:2002(E)

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;
– test specifications: in italic type;
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition of Part 1 concerns an adjective, the
adjective and the associated noun are also in bold .
The committee has decided that the contents of this publication will remain unchanged until
2004. At this date, the publication will be

60335-2-38 © IEC:2002(E) – 5 –

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.

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
correspondante 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.
La présente 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 la présente 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.

60335-2-38 © IEC:2002 – 9 –
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.

Part 2-38: Particular requirements

for commercial electric griddles and griddle grills

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 60335-2-38 consists of the fifth edition (2002) [documents
61E/400/FDIS and 61E/412/RVD] and its amendment 1 (2008) [documents 61E/596/FDIS and
61E/611/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 5.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
– 4 – 60335-2-38 © IEC:2002+A1:2008

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

griddles and griddle grills.
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;
– test specifications: in italic type;
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition of Part 1 concerns an adjective, the
adjective and the associated noun are also in bold .

The following differences exist in the countries indicated below.
– 6.1: Class 01 appliances are allowed (Japan).
– 6.2: For appliances intended to be installed in a kitchen, an appropriate degree of protection against harmful
ingress of water is required according to their height of installation (France).
– 13.2: Leakage current limits are different (Japan).
– 16.2: Leakage current limits are different (Japan).
– Clause 21: For appliances intended to be installed in a kitchen, different values of impact energy are
applicable according to the height of the impact point (France).

The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the maintenance result date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date,

the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may 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 the amendment 1 be adopted for implementation
nationally not earlier than 12 months from the date of publication.

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.

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrically operated commercial griddles
and griddle grills not intended 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.
NOTE 101 These appliances are used for example in restaurants, canteens, hospitals and commercial enterprises
such as bakeries, butcheries, etc.
The electrical part of appliances making use of other forms of energy is also within the scope
of this standard.
As far as is practicable, this standard deals with the common hazards presented by these
types of appliances.
NOTE 102 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may 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.
NOTE 103 This standard does not apply to
– appliances designed exclusively for industrial purposes;
– 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);
– continuous process appliances for the mass production of food;
– grillers and toasters (IEC 60335-2-48);
– appliances incorporating induction heating sources.

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.

60335-2-38 © IEC:2002+A1:2008 – 11 –

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 Addition:

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.
11.4 Replacement:
Appliances are operated under normal operation such that the total power input of the
appliance is 1,15 times rated power input. If it is not possible to switch on all heating
elements 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
most severe condition.
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 or electronic circuits are measured.
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.

– 12 – 60335-2-38 © IEC:2002+A1:2008

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 cooking
surface. If this temperature rise limit is exceeded above this level 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.
13.2 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.
For heating units with surfaces of glass-ceramic or similar material, a flat metal plate,
200 mm by 100 mm and 2 mm thick is used in place of the metal foil. The concavity of the
major dimension of the plate shall not exceed 0,1 mm.
The plate is put in any position on the surface for a period of 1 min before the leakage current
is measured.
13.3 Addition:
If there is earthed metal between live parts and the surface of glass-ceramic or similar
material, the flat metal plate is connected to earthed metal.
A test voltage of 1 000 V is then applied between live parts and the metal plate.
If there is no earthed metal between live parts and the surface of glass-ceramic or similar
material, the metal plate is not connected to earthed metal.

A test voltage of 3 000 V is then applied between live parts and the metal plate.
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.
15 Moisture resistance
This clause of Part 1 is applicable except as follows.

60335-2-38 © IEC:2002+A1:2008 – 13 –

15.1 Addition:
Appliances or any detachable electrical parts intended to be partially or completely
immersed in water for cleaning are also subjected to the tests of 15.102.

NOTE 101 Appliances other than stationary appliances or any detachable electrical parts not marked with a

line indicating the maximum depth of immersion, or for which there is no warning against partial or complete
immersion in the instructions, are considered to be appliances intended to be completely immersed in water for
cleaning.
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 so moved
around 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.
15.2 Modification:
Instead of the requirement, the following applies.
Appliances shall be constructed so that spillage of liquid in normal use does not affect their
electrical insulation.
Instead of the test specification paragraph referring to the liquid container, the following
applies:
A litre of cold water containing approximately 1 % NaCl is poured steadily over a period of
1 min on to the centre of the surface of the griddle plate.
15.3 Addition:
NOTE 101 If it is not possible to place the whole appliance in the humidity cabinet, parts containing electrical
components are tested separately, taking into account the conditions that occur in the appliance.
15.101 Appliances that are provided with a tap intended for filling or cleaning, shall be
constructed so that the water from the tap cannot come into contact with live parts.
Compliance is checked by the following test.
The tap is fully opened for 1 min with the appliance connected to a water supply having the
maximum water pressure indicated by the manufacturer. Tiltable and movable parts, including
lids, are tilted or placed in the most unfavourable positions. Swivelling outlets of water taps
are so positioned as to direct water on to those parts that will give the most unfavourable
result. Immediately following this treatment the appliance shall withstand an electric strength
test as specified in 16.3.
– 14 – 60335-2-38 © IEC:2002+A1:2008

15.102 Appliances or detachable electrical parts intended to be partially or completely
immersed in water for cleaning shall have adequate protection against the effects of

immersion.
Compliance is checked by the following tests.

The sample is operated under normal operation, except that cycling controls, if any, are
adjusted to the highest setting, the supply voltage being such that the power input of the

appliance is 1,15 times the rated power input.

When steady conditions are established or when the cycling control operates for the first time,

the connector is withdrawn or the supply switched off and the sample is immediately
immersed completely in water having a temperature between 10 °C and 25 °C, unless it
is marked with a line indicating the maximum depth of immersion, in which case it is immersed
to the depth indicated.
After 1 h of immersion, the sample is removed from the water and dried, care being taken to
ensure that all moisture is removed from the insulation in the vicinity of the pins of appliance
inlets. The leakage current is then measured on the assembled appliance, as described in 16.2.
The leakage current shall not exceed the value specified in 16.2.
After the treatment described above and the measurement of the leakage current, the sample
shall withstand an electric strength test as specified in 16.3, the test voltage being, however,
reduced to 1 000 V.
The sample is then operated under normal operation, the supply voltage being such that the
power input of the appliance is 1,15 times the rated power input for 10 days (240 h). During
this period, the sample is allowed to cool to approximately room temperature five times at
regular intervals.
After this period, the connector of the sample is withdrawn or the supply otherwise switched
off and the sample immediately immersed once more in water for 1 h as described above. It is
then dried and the leakage current is measured again as described in 16.2.
The leakage current shall not exceed the value specified in 16.2.
The sample shall then withstand an electric strength test as specified before, and inspection
shall show that water has not entered the appliance to any appreciable extent.
NOTE When inspecting the appliance for the presence of water, special attention is paid to parts of the appliance

in which electrical components are situated.
16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.
16.1 Addition:
For heating units with surfaces of glass-ceramic or similar material, the tests of 16.2 and
16.3 are made with the flat metal plate as described in 13.2.

60335-2-38 © IEC:2002+A1:2008 – 15 –

16.2 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
Addition:
If there is earthed metal between live parts and the surface of glass-ceramic or similar
material, the leakage current is measured for each of the heating units in turn, with the flat
metal plate connected to earthed metal.
The leakage current shall not exceed 1 mA per kW of the power input of the heating unit
being tested.
If there is no earthed metal between live parts and the surface of glass-ceramic or similar
material, the leakage current is measured between each pole of the supply and the flat metal
plate for each of the heating units in turn, the metal plate not being connected to earthed
metal.
For each measurement the leakage current shall not exceed 0,25 mA.
NOTE 101 For appliances intended to be used with a connector and intended to be partially or completely
immersed in water for cleaning, the appliance inlet may be dried, for example by means of blotting paper, before
applying the test voltage, if the appliance would not otherwise withstand this test.
16.3 Addition:
If there is earthed metal between live parts and the surface of glass-ceramic or similar
material, the flat metal plate is connected to earthed metal.
A test voltage of 1 250 V is then applied between live parts and the metal plate.
If there is no earthed metal between live parts and the surface of glass-ceramic or similar
material, the metal plate is not connected to earthed metal.
A test voltage of 3 000 V is then applied between live parts and the metal plate.

17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.

Part 2-38: Particular requirements

for commercial electric griddles and griddle grills

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) 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 consolidated version of the official IEC Standard and its amendments has been prepared
for user convenience.
IEC 60335-2-38 edition 5.2 contains the fifth edition (2002-11) [documents 61E/400/FDIS and

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.

SAFETY –
Part 2-38: Particular requirements

for commercial electric griddles and griddle grills

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrically operated commercial griddles
and griddle grills not intended for household use and similar 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.
NOTE 101 These appliances are used for the commercial processing of food, for example in kitchens of
restaurants, canteens, hospitals and in commercial enterprises such as bakeries, butcheries, etc.
The electrical part of appliances making use of other forms of energy is also within the scope
of this standard.
As far as is practicable, this standard deals with the common hazards presented by these
types of appliances.
NOTE 102 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may 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.
NOTE 103 This standard does not apply to
– appliances designed exclusively for industrial purposes;
– 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);
– appliances for continuous process appliances for the mass production of food;
– grillers and toasters (IEC 60335-2-48);
– appliances incorporating induction heating sources.

appliance and if not visible when the appliance is installed as in normal use, shall be included
in the instructions or on an additional label that can be fixed near the appliance after
installation.
NOTE 101 An example of such an fixed appliance is a built-in appliance hob.
7.101 If, during the test of Clause 11, the temperature rise of the side and rear walls of the
test corner above the level of the cooking surface exceeds 65 K, and/or during the test of
Clause 19 the temperature rise of the walls above and below the cooking surface level or of
the floor or ceiling exceeds 125 K, the installation instructions provided by the manufacturer
shall include the substance of the following that shall also be included on a non-permanent
label, for example a tie-on type, attached to the appliance.
Where this appliance is to be positioned in close proximity to a wall, partitions, kitchen
furniture, decorative finishes, etc., it is recommended that they be made of non-
combustible material; if not, they shall be clad with a suitable non-combustible heat-
insulating material, and that the closest attention be paid to fire prevention regulations.
Compliance is checked by inspection.
7.102 Equipotential bonding terminals shall be marked with symbol 5021 of IEC 60417-1.
These markings shall not be placed on screws, removable washers or other parts that can be
removed when conductors are being connected.
Compliance is checked by inspection.
7.103 Appliances or the detachable electrical parts of appliances intended to be partially
immersed in water for cleaning shall be marked with a line that clearly indicates the maximum
depth of immersion, together with the substance of the following warning:

Do not immerse beyond this line.
If there is any seam or seal that causes the appliance or part not to withstand the treatment
specified in 15.102, the line indicating the maximum depth of immersion shall be at least
50 mm below any such seam or seal when the appliance or the part is in the position in which
it is to be cleaned.
Compliance is checked by inspection and measurement.
8 Protection against access to live parts
This clause of Part 1 is applicable.

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 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:
Where the external accessible surfaces are suitably flat and access permits, then the test
probe of Figure 103 is used to measure the temperature rises of external accessible
surfaces specified in Table 101. The probe is applied with a force of 4 N ± 1 N to the surface
in such a way that the best possible contact between the probe and the surface is ensured.
The measurement is performed after a contact period of 30 s.
The probe may be held in place using a laboratory stand clamp or similar device. Any
measuring instrument giving the same results as the probe may be used.
11.4 Replacement:
Appliances are operated under normal operation such that the total power input of the
appliance is 1,15 times rated power input. If it is not possible to switch on all heating

+AMD2:2017 CSV © IEC 2017
elements 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

most severe condition.
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 or electronic circuits are measured.

11.7 Replacement:
Appliances are operated until steady conditions are established.
Steady conditions are considered to exist 60 min after reaching the temperatures defined for
normal operation.
When an appliance is assembled in combination with, equipped with or incorporating
accessories or other appliances the interaction shall be covered if they are provided to
operate simultaneously as stated by the manufacturer or by a common control.
NOTE 101 The duration of the test may consist of more than one cycle of operation.
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 cooking
surface. If this temperature rise limit is exceeded above this level then the requirements of
7.101 apply.
During the test, the temperature rises are monitored continuously and shall not exceed the
values shown in Table 3 and Table 101.
