Question 1: Has this subclause to be interpreted as:
"Add the following to the addition:
For accessible thermal insulation and non-metallic material on the external rear surfaces of an
appliance having a total area exceeding 75 cm that is in direct contact with the thermal
insulation, compliance is checked by the test of 30.2.101."
Subclause 30.2.101, final bullet point states:
• "that has an area not exceeding 75 cm that is in direct contact with the thermal
insulation is not tested. "
Question 2: Has this bullet point to be interpreted as:
• "that has a total area not exceeding 75 cm that is in direct contact with the thermal
insulation is not tested. "
Answers:
Question 1 –
From Subclause 30.2 addition, the following materials shall be tested:
1) Accessible thermal insulation
2) Non-metallic material on the rear surface of the appliance having an area exceeding
that is in direct contact with the thermal insulation
75 cm
Small holes (< 3 mm ) in the outer case were not intended to be considered as “accessible
thermal insulation”. These small < 3 mm holes are much smaller than the test probe B, so
therefore the thermal insulation of 3 mm holes is automatically not considered as accessible
thermal insulation without additional evaluation.
When testing accessible thermal insulation, the test is intended to be performed by applying
the flame to the accessible thermal insulation on the end product.
Question 2 – See question 1.

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 60335-2-24 edition 7.2 contains the seventh edition (2010-02) [documents 61C/459/FDIS and
61C/461/RVD], its amendment 1 (2012-05) [documents 61C/506/FDIS and 61C/509/RVD], its
amendment 2 (2017-04) [documents 61C/694/FDIS and 61C/700/RVD] its interpretation sheet 1
of April 2018 and 2 of March 2020.
In this Redline version, a vertical line in the margin shows where the technical content is
modified by amendments 1 and 2. Additions are in green text, deletions are in strikethrough red
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 subcommittee 61C:
Household appliances for refrigeration, of IEC technical committee 61: Safety of household
and similar electrical appliances.
This seventh edition constitutes a technical revision.
The principal changes in this edition as compared with the previous edition of IEC 60335-2-24
are as follows (minor changes are not listed):
– aligns the text with IEC 60335-1, and its Amendments 1 and 2;
– clarifies the term “household and similar use” (1, 7.12);
– updates marking requirements for supply terminals of battery operated appliances (7.6,
7.101);
– introduces requirements for appliances using transcritical refrigerant systems (3.112,

– introduces an enhanced flexing test (23.3);
– introduces requirements for accessible glass panels (22.116);
– clarifies tests for appliances using flammable refrigerants (22.107, Annex DD)
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
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 electric refrigerating
appliances, ice-cream appliances and ice-makers.
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 smaller roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.

The committee has decided that the contents of 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 this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below.
− 22.101： E12 and E17 lamp holders are checked as specified for E14 and B15 lamp holders. E26 lamp holder
is checked as specified for E27 and B22 lamp holders (Japan).
− 22.110：For unsealed glass tube heaters, the temperature requirements are different (Japan).

of its contents. Users should therefore print this publication using a colour printer.

+AMD2:2017 CSV  IEC 2017
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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-24: Particular requirements for refrigerating appliances,
ice-cream appliances and ice-makers

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of the following appliances, their rated
voltage being not more than 250 V for single-phase appliances, 480 V for other appliances
and 24 V d.c. for appliances when battery operated.
– refrigerating appliances for household and similar use;
– ice-makers incorporating a motor-compressor and ice-makers intended to be
incorporated in frozen food storage compartments;
– refrigerating appliances and ice-makers for use in camping, touring caravans and boats
for leisure purposes.
These appliances may be operated from the mains, from a separate battery or operated either
from the mains or from a separate battery.
This standard also deals with the safety of ice-cream appliances intended for household use,
their rated voltage being not more than 250 V for single-phase appliances and 480 V for
other appliances.
It also deals with compression-type appliances for household and similar use, which use
flammable refrigerants.
This standard does not cover features of the construction and operation of those
refrigerating appliances which are dealt with in other IEC standards.
Refrigerating appliances not intended for normal household use but which nevertheless may
be a source of danger to the public, such as
− refrigerating appliances used in staff kitchen areas in shops, offices and other working
environments,
− refrigerating appliances used in farm houses and by clients in hotels, motels and other
residential type environments,
− refrigerating appliances used in bed and breakfast type environments, and
− refrigerating appliances used in catering and similar non-retail applications
are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by
appliances that are encountered by all persons in and around the home. However, in general,
it does not take into account
– persons (including children) whose
• physical, sensory or mental capabilities or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.

+AMD2:2017 CSV  IEC 2017
NOTE 1 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 national health authorities, the national authorities
responsible for the protection of labour, the national water supply authorities and similar authorities.
NOTE 2 This standard does not apply to
– appliances intended to be used in the open air;
– 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 incorporating a battery intended as a power supply for the refrigerating function;
– appliances assembled on site by the installer;
– appliances with remote motor-compressors;
– motor-compressors (IEC 60335-2-34);
– commercial dispensing appliances and vending appliances (IEC 60335-2-75);
– commercial refrigerators and freezers used for the display of food products, including beverages, for retail sale
(IEC 60335-2-89);
– commercial ice-cream appliances.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) 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 IEC 60335-2-24 consists of the seventh edition (2010)
[documents 61C/459/FDIS and 61C/461/RVD] and its amendment 1 (2012) [documents
61C/506/FDIS and 61C/509/RVD]. It bears the edition number 7.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

60335-2-24  IEC:2010+A1:2012 – 5 –

This part of International Standard IEC 60335 has been prepared by subcommittee 61C:
Household appliances for refrigeration, of IEC technical committee 61: Safety of household

and similar electrical appliances.

This seventh edition cancels and replaces the sixth edition published in 2002 including its

Amendment 1 (2005) and Amendment 2 (2007). It constitutes a technical revision.

The principal changes in this edition as compared with the previous edition of IEC 60335-2-24

are as follows (minor changes are not listed):

– aligns the text with IEC 60335-1, and its Amendments 1 and 2;

– clarifies the term “household and similar use” (1, 7.12);
– updates marking requirements for supply terminals of battery operated appliances (7.6,
7.101);
– introduces requirements for appliances using transcritical refrigerant systems (3.112,
3.113, 3.114, 3.115, 3.116, 7.1, 7.6, 7.12.1, 22.103, 24.1.4, 24.102);
– introduces an enhanced flexing test (23.3);
– introduces requirements for accessible glass panels (22.116);
– clarifies tests for appliances using flammable refrigerants (22.107, Annex DD)
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
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 electric refrigerating
appliances, ice-cream appliances and ice-makers.
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 smaller roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
A list of all parts of the IEC 60335 series, under the general title: Household and similar
electrical appliances – Safety, can be found on the IEC website.

– 6 – 60335-2-24  IEC:2010+A1:2012

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 this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below.
− 22.101： E12 and E17 lamp holders are checked as specified for E14 and B15 lamp holders. E26 lamp holder
is checked as specified for E27 and B22 lamp holders (Japan).
− 22.110：For unsealed glass tube heaters, the temperature requirements are different (Japan).

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 publication 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 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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –

SAFETY –
Part 2-24: Particular requirements for refrigerating appliances,

ice-cream appliances and ice-makers

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of the following appliances, their rated
voltage being not more than 250 V for single-phase appliances, 480 V for other appliances
and 24 V d.c. for appliances when battery operated.
– refrigerating appliances for household and similar use;
– ice-makers incorporating a motor-compressor and ice-makers intended to be
incorporated in frozen food storage compartments;
– refrigerating appliances and ice-makers for use in camping, touring caravans and boats
for leisure purposes.
These appliances may be operated from the mains, from a separate battery or operated either
from the mains or from a separate battery.
This standard also deals with the safety of ice-cream appliances intended for household use,
their rated voltage being not more than 250 V for single-phase appliances and 480 V for
other appliances.
It also deals with compression-type appliances for household and similar use, which use
flammable refrigerants.
This standard does not cover features of the construction and operation of those
refrigerating appliances which are dealt with in other IEC standards.
Refrigerating appliances not intended for normal household use but which nevertheless may
be a source of danger to the public, such as
− refrigerating appliances used in staff kitchen areas in shops, offices and other working
environments,
− refrigerating appliances used in farm houses and by clients in hotels, motels and other

residential type environments,
− refrigerating appliances used in bed and breakfast type environments, and
− refrigerating appliances used in catering and similar non-retail applications
are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by
appliances that are encountered by all persons in and around the home. However, in general,
it does not take into account
– persons (including children) whose
• physical, sensory or mental capabilities or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.

60335-2-24  IEC:2010+A1:2012 – 9 –

NOTE 1 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 national health authorities, the national authorities

responsible for the protection of labour, the national water supply authorities and similar authorities.

NOTE 2 This standard does not apply to

– appliances intended to be used in the open air;

– 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 incorporating a battery intended as a power supply for the refrigerating function;
– appliances assembled on site by the installer;
– appliances with remote motor-compressors;
– motor-compressors (IEC 60335-2-34);
– commercial dispensing appliances and vending appliances (IEC 60335-2-75);
– commercial refrigerators and freezers used for the display of food products, including beverages, for retail sale
(IEC 60335-2-89);
