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.

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.

for commercial electric deep fat fryers

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 60335-2-37 consists of the fifth edition (2002) [documents
61E/399/FDIS and 61E/411/RVD] and its amendment 1 (2008) [documents 61E/595/FDIS and
61E/610/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 – 60335-2-37 © 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
deep fat fryers.
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.

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;
– in many countries, additional requirements are specified for pressure appliances.
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.

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.
NOTE 101 See also 11.7.
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 – 60335-2-37 © IEC:2002+A1:2008
Tilting motors are operated immediately after the appliance has reached steady conditions, for
one full cycle of operation (one cycle being from the fully up position to the fully down position
and back to the fully up position).
Lifting motors are similarly operated, but for three such cycles.
11.8 Addition:
The maximum temperature of the oil shall not exceed 200 °C. During the test, the pressure
relief device shall not operate.

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 instruction sheet, 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.
60335-2-37 © IEC:2002+A1:2008 – 13 –
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.
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.
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, the supply voltage being such that the
power input of the appliance is 1,15 times the rated power input until steady conditions are
established.
The connector is then withdrawn or the supply otherwise switched off and the sample
is immediately emptied and then 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.

– 14 – 60335-2-37 © IEC:2002+A1:2008
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 as above 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 emptied and 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.
16.2 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:
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.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
18 Endurance
This clause of Part 1 is not applicable.

60335-2-37 © IEC:2002+A1:2008 – 15 –
19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Addition:
A control or switching device that is intended for different settings corresponding to different
functions of the same part of the appliance and which are covered by different standards is in
addition set in the most severe setting irrespective of the manufacturer's instructions.
Appliances provided with a control limiting the pressure during the test of Clause 11 are
also subjected to the tests of 19.4 with this control rendered inoperative.
NOTE 101 Continuous blowing-off of the pressure relief device is in itself disregarded.
19.2 Addition:
The test is carried out in two parts as follows.
a) With a quantity of oil less than the minimum such that the highest oil temperature is obtained,
the test is started from cold with the thermal control at its highest setting and with the lid(s)
open, removed or closed whichever is the most unfavourable condition, unless the appliance
is constructed so that it cannot be operated unless the lid(s) is(are) closed.
b) When the appliance has returned to room temperature it is refilled and then drained for 1
h but not dried off. The test is then started with the thermal control at its highest setting
and with the lid(s) open, removed or closed whichever is the most unfavourable condition,
unless the appliance is constructed so that it cannot be operated unless the lid(s) is(are)
closed. During this test no oil, other than the oil on the elements, shall ignite and no
flames shall be propagated to other parts of the appliance.
19.3 Addition:
Any adjustable temperature or pressure control within the appliance that is preset for correct
operation but is not locked in position is adjusted to its most unfavourable position.
19.4 Addition:
NOTE 101 The main contacts of the contactor intended for switching on and off the heating element(s) in normal
use are locked in the "ON" position. However, if two contactors operate independently of each other or if one
contactor operates two independent sets of main contacts, these contacts are locked in the "ON" position in turn.
19.13 Addition:
During the first part of the test of 19.2 and 19.3, the temperature of the oil shall not exceed
230 °C measured at any point not closer than 5 mm from any surface.
During the test of 19.4 the temperature of the oil measured in accordance with 11.3 shall not
exceed 230 °C.
20 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows.
20.1 Addition:
Detachable parts and loose items such as baskets and lids are placed in their most
unfavourable positions.

20.2 Modification:
Add the following after the first requirement paragraph.
This applies also to parts necessary to effect the tilting operation, i.e. handles or wheels.
21 Mechanical strength
This clause of Part 1 is applicable.
22 Construction
This clause of Part 1 is applicable except as follows.
22.7 Replacement:
Appliances that operate at a pressure in excess of atmospheric pressure (over-pressure) shall
incorporate a suitable pressure relief device that prevents excessive pressure.
Compliance is checked by operating the appliance at rated power input with the pressure
controls rendered inoperative.
The pressure relief device shall operate during this test so as to prevent the internal pressure
exceeding the rated pressure by more than 20 %.
22.101 For three-phase appliances, thermal cut-outs protecting circuits with heating
elements, and those for motors of which the unexpected starting may cause a hazard, shall
be of the non-self-resetting and trip-free type, and shall provide all-pole disconnection from
related supply circuits.
For single-phase appliances and for single-phase heating elements and/or motors connected
between one phase and neutral or between phase and phase, thermal cut-outs protecting
circuits with heating elements, and those for motors of which the unexpected starting may
cause a hazard, shall be of the non-self-resetting and trip-free type, and shall provid

Particular requirements for commercial electric doughnut fryers
and deep fat fryers
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 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 60335-2-37 consists of the fifth edition (2002) [documents
61E/399/FDIS and 61E/411/RVD], its amendment 1 (2008) [documents 61E/595/FDIS and
61E/610/RVD] and its amendment 2 (2011) [documents 61E/680/FDIS and 61E/685/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.
– 4 – 60335-2-37  IEC:2002+A1:2008
+A2:2011
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
deep fat fryers.
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 stability 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.

SAFETY –
Particular requirements for commercial electric doughnut fryers
and deep fat fryers
1 Scope
This clause of Part 1 is replaced by the following.
This international Standard deals with the safety of electrically operated commercial deep fat
fryers and doughnut fryers including pressurized types with a pressure not exceeding
0,5 bar (50 kPa) and a pressure (bar) volume liters product of 200. These appliances are not
intended for household 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 processing food for commercial consumption, 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;
– in many countries, additional requirements are specified for pressure appliances.
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 mass production of food.

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.
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, the supply voltage being such that the
power input of the appliance is 1,15 times the rated power input until steady conditions are
established.
The connector is then withdrawn or the supply otherwise switched off and the sample
is immediately emptied and then 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 as above 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 emptied and 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.
