Introduction
p Add:
An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this
standard are fully covered by the Low Voltage Directive, 2006/95/EC. For products having mechanical
moving parts, a risk assessment in accordance with the Machinery Directive, 2006/42/EC, has shown that
the risks are mainly of electrical origin and consequently this directive is not applicable. However, the
relevant essential safety requirements of the Machinery Directive are covered by this standard together
with the principal objectives of the Low Voltage Directive.

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

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

60335-2-24 © IEC:2010 – 9 –
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
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.

4 General requirement
This clause of Part 1 is applicable except as follows.
Addition:
NOTE 101 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.
