Household and similar electrical appliances - Safety - Part 2-24: Particular requirements for refrigerating appliances, ice-cream appliances and ice makers
IEC 60335-2-24:2010 deals with the safety of the following appliances, refrigerating appliances for household and similar use; ice-makers incorporating a motor-compressor and ice-makers intended to be used in frozen food storage compartments; refrigerating appliances and ice-makers for use in camping, touring caravans and boats for leisure purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances and 24 V d.c for appliances when battery operated. 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 with compression-type appliances for household and similar use, which use flammable refrigerants. The principal changes in this edition as compared with the previous edition are as follows:
- Aligns the text with IEC 60335-1, and its amendments;
- clarifies the term "household and similar use";
- updates marking requirements for supply terminals of battery operated appliances;
- introduces requirements for appliances using transcritical refrigerant systems;
- introduces an enhanced flexing test;
- introduces requirements for accessible glass panels;
- clarifies tests for appliances using flammable refrigerants. 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 themselfs 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.

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.

SC 61C interpretation sheet on: Subclause 30.2 of IEC 60335-2-24:2010/AMD2:2017
Subclause 30.2 states:
"Add the following to the addition:
For accessible thermal insulation and non-metallic material on the external rear surfaces of an
appliance having an area exceeding 75 cm that is in direct contact with the thermal
insulation, compliance is checked by the test of 30.2.101."

– 2 – IEC 60335-2-24:2010/AMD2:2017/
ISH2:2020 IEC 2020
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 publi
