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 third edition cancels and replaces the second edition published in 1997 and its
amendment 1 (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/408/FDIS 61E/420/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
kitchen machines.
– 4 – 60335-2-64 © 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.

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 2-64: Particular requirements for commercial

electric kitchen machines
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 60335-2-64 consists of the third edition (2002) [documents
61E/408/FDIS and 61E/420/RVD] and its amendment 1 (2007) [documents 61E/587/FDIS and
61E/592/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 3.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
– 4 – 60335-2-64 © IEC:2002+A1:2007(E)

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

kitchen machines.
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 if their rated voltage does not exceed 150 V (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).

A bilingual version of this publication may be issued at a later date.

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.

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.

This standard also applies to appliances which, in order to facilitate transport, are supplied in
several parts (sub-assemblies) which, when assembled at the place of installation, form a
constructional unit without the use of any additional parts.
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 103 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.

Part 2-64: Particular requirements for commercial
electric kitchen machines
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 third edition cancels and replaces the second edition published in 1997 and its
amendment 1 (2000). It constitutes a technical revision.
This bilingual version (2016-01) corresponds to the monolingual English version, published in
2002-11.
The text of this part of IEC 60335 is based on the following documents:
FDIS Report on voting
61E/408/FDIS 61E/420/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.
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
kitchen machines.
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
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
The following differences exist in the countries indicated below.
– 6.1: Class 01 appliances are allowed if their rated voltage does not exceed 150 V (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).

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.

This standard also applies to appliances which, in order to facilitate transport, are supplied in
several parts (sub-assemblies) which, when assembled at the place of installation, form a
constructional unit without the use of any additional parts.
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 103 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;

3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions
The appliance is operated without load at rated voltage and with controls intended to be
adjusted by the user set at maximum until steady conditions are established. The appliance is
then loaded in appropriate steps, the supply voltage being maintained at its original value. For
each step, steady conditions have to be established before increasing the load. This operation
is repeated until just before an overload release operates, or until the steady condition with
the highest temperature has been attained.
NOTE 101 The load may be achieved by using an electrical or mechanical brake.
Where it is not possible or is impractical to apply effectively an electrical or mechanical brake,
the load is 115 % of the input measured when the appliance is operated without load at rated
voltage and normal operating temperature, and with controls intended to be adjusted by the
user set at maximum.

specified in 26.6, and other appliances are tested as delivered.
Detachable parts are removed or in position, whichever is the most unfavourable.
Water outlets, if any, are blocked.
The water containers of appliances intended to be filled with water by hand are completely
filled with water containing approximately 1 % NaCl and a further quantity, equal to 15 % of
the capacity of the container but not more than 10 l, is poured in steadily over a period of
1 min.
Appliances intended to be filled by a manually operated tap or automatically are connected to
a water supply having the maximum supply pressure indicated by the manufacturer. The
means for controlling the incoming water is held fully open, and the filling continued for 1 min
after the first evidence of overflow, or until a further protective system operates to stop the
inflow.
With the container filled with water, the appliance is then operated at rated voltage for 15 s.
Lids or covers are in position or removed, whichever is the most unfavourable.
The appliance shall then withstand the electric strength test of 16.3, and inspection shall
show that there is no trace of water on the insulation that could result in a reduction of
clearances and creepage distances below the values specified in Clause 29.
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 position. 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.
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 appliances without heating elements 3,5 mA
– for appliances with heating elements, 1 mA per kW rated power input of the
cord and plug connected  appliance with a maximum of 10 mA

– 14 – IEC 60335-2-64:2002  IEC 2002
– for other appliances with heating elements 1 mA per kW rated power input of the
appliance with no maximum
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
18 Endurance
This clause of Part 1 is applicable.
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 that are covered by different standards is, in
addition, set in the most severe setting irrespective of the instructions for use.
19.2 Addition:
Appliances are operated with empty heated containers.
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.
20 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows.
20.2 Addition:
Add the following after the second paragraph of the requirement.
Covers and the like, protecting danger zones within the operating range of the appliance,
shall be detachable only when the risk is excluded by other means.
NOTE 101 Parts that do not move more than 4 mm away from each other are not regarded as dangerous crushing
(squashing) and shearing zones.
NOTE 102 Drawing-in zones can only occur during operations where uncovered movable parts move past
stationary and/or moving parts.
Add the following after the first paragraph of the test specification.
However, for feed apertures and discharge apertures, unless otherwise specified, the test is
carried out with test probe B of IEC 61032, but having a non-circular stop face with a diameter
of 56 mm instead of 50 mm and with the distance between the tip of the test probe and the
stop face being 120 mm. The 75 mm diameter guard is removed. The test probe is not
inserted into the aperture for a linear distance of more than 850 mm, measured from the tip of
the probe, if the aperture has a largest dimension of less than 150 mm.

NOTE 103 Moving parts that can be touched by the test probe through discharge apertures are not considered to
be dangerous if they have a smooth surface or are constructed so that the risk of entrapment or injury is negligible.
For some appliances complete protection is impracticable and the test with the test probe is
therefore not carried out. Examples of such appliances are
– hand-held appliances;
– slicers;
– tin openers;
– pastry rollers;
– noodle strip cutters;
– sieving machines;
– peelers (discharge apertures only);
– bone saws (circular or band type);
– citrus juice squeezers;
– egg beaters designated as attachable accessories;
– knife sharpeners.
Modification:
Delete Note 1.
20.101 Locking devices, the release of which could create a hazard, shall be constructed so
that they cannot be actuated accidentally.
Compliance is checked by a test with test probe B of IEC 61032. It shall not be possible to
release the locking device with the probe.
20.102 Fixing devices of functional parts, such as attachable accessories, shall not work
loose unintentionally. Driven shafts that might constitute a hazard – except within the
operating range – shall be adequately protected against accidental contact.
Compliance is checked by inspection and by a test using test probe B of IEC 61032.
20.103 Appliances, or parts of appliances, that are designed to tilt in normal use shall not
give rise to any hazard. Accidental tilting from any position, even in the case of supply
interruption, shall be prevented and there shall be no crushing zone between the tilting part
and the appliance except at the bumper point when the part is fully tilted.
Compliance is checked by inspection, by manual test and by switching off the supply to the
appliance at any time during the tilting operation.
NOTE The requirement may be met by, for example, one of the following means:
– providing switches that have to be kept switched on by hand;
– limiting the rate of motion (peripheral speed) to 50 mm/s;
– protecting danger zones by means of appropriate guards;
– maintaining moving parts securely in position – even in the case of a fault.
If the appliance or part is tilted manually, it shall not be possible to adversely influence the
tilting action other than by the intended means.
Compliance is checked by inspection and by applying a force of 340 N at any point on the
tiltable part.
– 16 – IEC 60335-2-64:2002  IEC 2002
20.104 Moving rollers shall be adequately protected at their drawing-in zones, that is by
means of a safety screen or non-driven protective rollers and/or bars, unless they are
spring-loaded with a maximum pressure of 50 kPa, with an emergency switching device, and
that the gap between the pair of rollers is at least 60 mm.
Compliance is checked by inspection, measurement and manual test.
20.105 Switches shall be positioned within easy reach of the operator's hand. Start switches
shall be secured against accidental actuation, if their actuation could result in a hazard.
Compliance is checked by inspection and by applying a cylindrical rod having a diameter of
40 mm and a hemispherical end to the switch. The appliance shall not operate.
20.106 Devices, such as sliding feed tables, product holders, stop plates, etc., shall ensure
safe working within the operating range.
Compliance is checked by inspection, measurement and manual test.
NOTE This requirement may be met by using for example
– a product holder that protects the whole of the operating range and that is so undetachably fixed to the
sliding feed table, that it automatically drops when the feed table is folded back, and that cannot be moved
more than 80 mm away from the knife;
– a product holder that is automatically moved up to the knife, and that is provided with a guard at the
stop-plate and a finger-guard at the sliding feed table;
– in the case of gravity-driven systems, a back wall on the feed table, with a height equal to the diameter of the
knife.

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.

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.

This standard also applies to appliances which, in order to facilitate transport, are supplied in
several parts (sub-assemblies) which, when assembled at the place of installation, form a
constructional unit without the use of any additional parts.
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 103 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.

that can be on at one time; where there are several such combinations possible, that giving the highest power input
is used in determining the rated power input.
3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions
The appliance is operated without load at rated voltage and with controls intended to be
adjusted by the user set at maximum until steady conditions are established. The appliance is
then loaded in appropriate steps, the supply voltage being maintained at its original value. For
each step, steady conditions have to be established before increasing the load. This operation
is repeated until just before an overload release operates, or until the steady condition with
the highest temperature has been attained.
NOTE 101 The load may be achieved by using an electrical or mechanical brake.
Where it is not possible or is impractical to apply effectively an electrical or mechanical brake,
the load is 115 % of the input measured when the appliance is operated without load at rated

with the lightest permissible type of flexible cable or cord of the smallest cross-sectional area

specified in 26.6, and other appliances are tested as delivered.

Detachable parts are removed or in position, whichever is the most unfavourable.

Water outlets, if any, are blocked.

The water containers of appliances intended to be filled with water by hand are completely

filled with water containing approximately 1 % NaCl and a further quantity, equal to 15 % of
the capacity of the container but not more than 10 l, is poured in steadily over a period of
1 min.
Appliances intended to be filled by a manually operated tap or automatically are connected to
a water supply having the maximum supply pressure indicated by the manufacturer. The
means for controlling the incoming water is held fully open, and the filling continued for 1 min
after the first evidence of overflow, or until a further protective system operates to stop the
inflow.
With the container filled with water, the appliance is then operated at rated voltage for 15 s.
Lids or covers are in position or removed, whichever is the most unfavourable.
The appliance shall then withstand the electric strength test of 16.3, and inspection shall
show that there is no trace of water on the insulation that could result in a reduction of
clearances and creepage distances below the values specified in Clause 29.
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 position. 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.
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 appliances without heating elements 3,5 mA
– for appliances with heating elements, 1 mA per kW rated power input of the
cord and plug connected  appliance with a maximum of 10 mA

– 14 – IEC 60335-2-64:2002+AMD1:2007 CSV

 IEC 2008
– for other appliances with heating elements 1 mA per kW rated power input of the

appliance with no maximum
17 Overload protection of transformers and associated circuits

This clause of Part 1 is applicable.

18 Endurance
This clause of Part 1 is applicable.
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 that are covered by different standards is, in
addition, set in the most severe setting irrespective of the instructions for use.
19.2 Addition:
Appliances are operated with empty heated containers.
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.
20 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows.
20.2 Addition:
Add the following after the second paragraph of the requirement.

Covers and the like, protecting danger zones within the operating range of the appliance,
shall be detachable only when the risk is excluded by other means.
NOTE 101 Parts that do not move more than 4 mm away from each other are not regarded as dangerous crushing
(squashing) and shearing zones.
NOTE 102 Drawing-in zones can only occur during operations where uncovered movable parts move past
stationary and/or moving parts.
Add the following after the first paragraph of the test specification.
However, for feed apertures and discharge apertures, unless otherwise specified, the test is
carried out with test probe B of IEC 61032, but having a non-circular stop face with a diameter
of 56 mm instead of 50 mm and with the distance between the tip of the test probe and the
stop face being 120 mm. The 75 mm diameter guard is removed. The test probe is not
inserted into the aperture for a linear distance of more than 850 mm, measured from the tip of
the probe, if the aperture has a largest dimension of less than 150 mm.

 IEC 2008
NOTE 103 Moving parts that can be touched by the test probe through discharge apertures are not considered to

be dangerous if they have a smooth surface or are constructed so that the risk of entrapment or injury is negligible.

For some appliances complete protection is impracticable and the test with the test probe is

therefore not carried out. Examples of such appliances are

– hand-held appliances;
– slicers;
– tin openers;
– pastry rollers;
– noodle strip cutters;
– sieving machines;
– peelers (discharge apertures only);
– bone saws (circular or band type);
– citrus juice squeezers;
– egg beaters designated as attachable accessories;
– knife sharpeners.
Modification:
Delete Note 1.
20.101 Locking devices, the release of which could create a hazard, shall be constructed so
that they cannot be actuated accidentally.
Compliance is checked by a test with test probe B of IEC 61032. It shall not be possible to
release the locking device with the probe.
20.102 Fixing devices of functional parts, such as attachable accessories, shall not work
loose unintentionally. Driven shafts that might constitute a hazard – except within the
operating range – shall be adequately protected aga

Part 2-64: Particular requirements for commercial

electric kitchen machines
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 60335-2-64 edition 3.2 contains the third edition (2002-11) [documents 61E/408/FDIS and
61E/420/RVD], its amendment 1 (2007-12) [documents 61E/587/FDIS and 61E/592/RVD] and its

text. A separate Final version with all changes accepted is available in this publication.

+AMD2:2017 CSV  IEC 2017
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.

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
kitchen machines.
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 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,

NOTE 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 this publication be adopted for implementation

nationally not earlier than 12 months or later than 36 months from the date of publication.

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates

that it contains colours which are considered to be useful for the correct

understanding of its contents. Users should therefore print this document using a

colour printer.

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.

electric kitchen machines
1 Scope
This clause of Part 1 is replaced by the following.
This standard deals with the safety of electrically operated commercial kitchen machines 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 the commercial processing of food, for example in kitchens of
restaurants, canteens, hospitals and in commercial enterprises such as bakeries, butcheries, etc.
NOTE 102 Examples of kitchen machines are
– mixers;
– liquid or food blenders;
– kneaders;
– beaters;
– shredders;
– graters;
– mincers;
– slicers;
– peelers;
– tin openers;
– coffee grinders;
– machines used for washing and/or drying food;
– portioning machines;
– pastry rollers;
– noodle strip cutters;
– food processors;
– beam mixers.
This standard also applies to appliances which, in order to facilitate transport, are supplied in
several parts (sub-assemblies) which, when assembled at the place of installation, form a
constructional unit without the use of any additional parts.
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 103 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.
+AMD2:2017 CSV  IEC 2017
NOTE 104 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;

– independent conveying equipment, such as food distribution belts.

is used in determining the rated power input.
3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions
The appliance is operated without load at rated voltage and with controls intended to be
adjusted by the user set at maximum until steady conditions are established. The appliance is
then loaded in appropriate steps, the supply voltage being maintained at its original value. For
each step, steady conditions have to be established before increasing the load. This operation
is repeated until just before an overload release operates, or until the steady condition with
the highest temperature has been attained.
NOTE 101 The load may be achieved by using an electrical or mechanical brake.
Where it is not possible or is impractical to apply effectively an electrical or mechanical brake,
the load is 115 % of the input measured when the appliance is operated without load at rated
voltage and normal operating temperature, and with controls intended to be adjusted by the
user set at maximum.
