Part 2-24: Particular requirements for refrigerating appliances, ice-cream
appliances and ice-makers
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60335-2-24 has been prepared by subcommittee 61C: Safety of refrigeration appliances
for household and commercial use, of IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.

j) requirement for the evaluation of motor-compressor has been updated (24.1);
k) Annex DD has been cancelled and the text copied to Annex A;
l) design pressure has been changed in maximum allowable pressure (3.8.101).
The text of this International Standard is based on the following documents:
Draft Report on voting
61C/929/FDIS 61C/931/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
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.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) 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 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 small 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.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations can 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).
– 22.117: Only the first two dashed items in the first paragraph of the requirement are allowed (Australia and New
Zealand).
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or
• revised.

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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 and SC 61C supporting documents on the IEC websites.
https://www.iec.ch/tc61/supportingdocuments
https://www.iec.ch/sc61c/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
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 can 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 publications, basic safety publications and group safety publications 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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.
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 part of IEC 60335 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 DC
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 intended for household use;
– refrigerating appliances and ice-makers for applications similar to household use such as
for camping, in leisure accommodation vehicles, on boats for leisure purposes and on
board ships;
– mobile refrigerating appliances.
These appliances can be operated from the mains, from a separable battery or operated either
from the mains or from a separable battery or from other sources of energy (gas, liquid and
solid fuel).
This standard deals also with refrigerating appliances intended for the use on boats for leisure
purposes and on board ships, for which the normative Annex FF is applicable.
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 can
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.

IEC 60335-2-24:2025 © IEC 2025 – 9 –
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 whose
• physical, sensory or mental capabilities or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction.
Attention is drawn to the fact that
– for appliances intended to be used in vehicles, leisure accommodation vehicles, boats for
leisure purposes, on board ships or aircraft, additional requirements can 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;
– for appliances that are operated additional from other sources of energy (gas, liquid and
solid fuel), additional requirements can be necessary.
This standard does not apply to
– appliances intended for outdoor use, except for mobile refrigerating appliances;
– 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 refrigerating appliances and ice-makers with an incorporated or remote
refrigerant unit or motor-compressor (IEC 60335-2-89);
– professional ice-cream makers (IEC 60335-2-118).

PS
maximum pressure that a refrigerating circuit or a part of a refrigerating circuit or component is
designed for, as specified by the manufacturer
Note 1 to entry: For example a refrigerating circuit can have the high side, low side or intermediate PS.
3.8.102
flammable refrigerant
refrigerant with a safety classification of A2L, A2 or A3 in accordance with ISO 817
Note 1 to entry: For refrigerant blends which have more than one safety classification, the most unfavourable
classification is taken for the purposes of this definition.
4 General requirement
This clause of Part 1 is applicable except as follows.
Addition:
The use of flammable refrigerants involves additional hazards which are not associated with
appliances using non-flammable refrigerants.
This standard addresses the hazards due to ignition of leaked flammable refrigerant by
potential ignition sources associated with the appliance.
The hazard due to ignition of leaked flammable refrigerant by an external potential ignition
source associated with the environment in which the appliance is installed is compensated by
the low probability of ignition.
5 General conditions for the tests
This clause of Part 1 is applicable except as follows.
5.2 Addition:
At least one additional specially prepared sample is required for the tests of 22.107.
Unless the motor-compressor conforms to IEC 60335-2-34 and is classified as being protected
by a motor-compressor protection system, at least one additional specially prepared sample is
required for the test of 19.1.
At least one additional sample of the fan motor, thermal motor protector combination can be
required for the test of 19.1.
The tests of 22.7 and 19.106 may be performed on separate samples.
Due to the potentially hazardous nature of the tests of 22.107, 22.108 and 22.109, special
precautions shall be taken when performing the tests.

5.3 Addition:
Before starting the tests,
– ice-cream appliances are operated empty at rated voltage for 1 h, or for the maximum
setting of an incorporated timer, whichever is shorter;
– other compression-type appliances shall be operated at rated voltage for at least 24 h,
then switched off and left to stand for at least 12 h.
The test of 11.102 is carried out immediately after the tests of Clause 13.
The test of 15.105 is carried out immediately after the test of 11.102.
The tests of 15.101.1, 15.101.2, 15.103 and 15.104 are carried out immediately after the test
of 15.2.
5.4 Replacement:
Tests are carried out using each source of energy (electricity, gas, liquid and solid fuel) in turn.
Gas appliances are supplied at the appropriate rated pressure.
Tests are additionally carried out with all combinations of energy sources supplied
simultaneously unless this is prevented by interlocking devices.
5.7 Addition:
For ice-cream appliances, tests specified in Clauses 10, 11 and 13 are carried out at an
ambient temperature of 23 °C ± 2 °C.
For other appliances, tests specified in Clauses 10, 11, 13 and Subclause 19.103 are carried
out at an ambient temperature of
– 32 °C ± 1 °C on appliances of extended temperate (SN) and temperate (N) classes;
– 38 °C ± 1 °C on appliances of subtropical (ST) class;
– 43 °C ± 1 °C on appliances of tropical (T) class.
Before starting these tests, the appliance with the doors or lids open is brought to within 2 K of
the ambient temperature specified.
Appliances classified for several climatic classes are tested at the ambient temperature relevant
to the highest climatic class.
Other tests are carried out at an ambient temperature of 20 °C ± 5 °C.
Steady conditions are considered to be established when three successive readings of the
temperature, taken at approximately 60 min intervals, at the same point of any operating cycle,
do not differ by more than 1 K.
5.8.1 Addition:
Appliances which can be battery-operated are tested at the more unfavourable polarity when
the supply terminals or terminations for the connection of the battery have no indication for
polarity.
