SAFETY OF HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
Part 2-24: Particular requirements for refrigerating appliances,
ice-cream appliances and ice-makers
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.
International Standard IEC 60335-2-24 has been prepared by subcommittee 61C: Household
appliances for refrigeration, of IEC technical committee 61: Safety of household and similar
electrical appliances.
It forms the fifth edition of IEC 60335-2-24 and replaces the fourth edition published in 1997,
its amendment 1 (1998) and amendment 2 (1999).
The text of this standard is based on the fourth edition, amendments 1 and 2 and the following
documents:
FDIS Report on voting
61C/176/FDIS 61C/183/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.
Annex AA forms an integral part of this standard.
Annex BB is for information only.
The contents of the corrigendum of March 2001 have been included in this copy.
60335-2-24 © IEC:2000(E) – 5 –
This part 2-24 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 third edition (1991) of that standard.
This part 2-24 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.
Where a particular subclause of part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. Where this standard states "addition", "modification# or
"replacement", the relevant text in part 1 is to be adapted accordingly.
NOTE 1 In this standard, 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 2. When a definition of part 1 concerns an adjective, the adjective
and the associated noun are also in bold.
NOTE 2 Subclauses, notes, tables and figures which are additional to those in part 1 are numbered starting from
101, annexes which are additional to those in part 1 are lettered AA, BB, etc.
The following additional differences exist in some countries:
– 6.101: Only appliances of tropical class T are allowed (Australia, Israel, New Zealand).
A bilingual version of this standard may be issued at a later date.

SAFETY OF HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
Part 2-24: Particular requirements for refrigerating appliances,
ice-cream appliances and ice-makers
1 Scope
This clause of part 1 is replaced by:
This 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 ISO standards.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used by laymen in shops, in light
industry and on farms, are within the scope of this standard.
