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.

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 which 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 2-4: Particular requirements for spin extractors

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of
– stand alone electric spin extractors, and
– spin extractors incorporated in washing machines that have separate containers for
washing and spin extraction
for household and similar purposes that have a capacity not exceeding 10 kg of dry cloth and
a drum peripheral speed not exceeding 50 m/s, their rated voltages being not more than
250 V for single-phase appliances and 480 V for other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as spin extractors intended to be used by laymen in shops, in light
industry and on farms, and spin extractors for communal use in blocks of flats or in
launderettes are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances
which 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.
NOTE 101 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 the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
NOTE 102 This standard does not apply to
– appliances intended 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).

specified in Table 13.
The inlet to the discharge pump or to the gravity drain is blocked. The drum is filled as
specified for normal operation, the mass of water being twice the mass of the dry textile
material. Any water remaining after the saturation process is poured into the appliance, which
is supplied at rated voltage and operated for 1 min or the maximum period allowed by the
programmer or timer, whichever is shorter.
In addition, continuous-flow rinsing appliances having a vertical axis are completely filled with
saturated textile material and 10 l of water is poured in over a period of 20 s. The appliance is
then operated while supplied at rated voltage.
For all appliances, 0,5 l of water containing approximately 1 % NaCl and 0,6 % of rinsing
agent, as specified in Annex AA, the solution is poured rapidly over the top of the appliance in
the most unfavourable way so that the spillage solution also flows over the surface of the
appliance that incorporate controls and other places where it may penetrate the appliance
enclosure, the controls being placed in the on most unfavourable position. The controls are
then operated through their working range, this operation being repeated after a period of 5
min.
+AMD2:2017 CSV  IEC 2017
The appliance shall then withstand the electric strength test of 16.3 and inspection shall show
that there is no trace of water on insulation that could result in a reduction of clearances or

that braking mechanisms and lid interlocks withstand the stresses to which they may be
exposed in normal use.
Compliance is checked by the following test.
The appliance is supplied at 1,06 times rated voltage and operated under normal operation
until the motor has reached its maximum speed.
The lid is then fully opened. The test is repeated after the drum has been at rest for a period
long enough to ensure that the appliance does not attain an excessive temperature.
The test is carried out
– for braking mechanisms:

Part 2-4: Particular requirements for spin extractors

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
International Standard IEC 60335-2-4 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This sixth edition cancels and replaces the fifth edition published in 2002 including its
Amendment 1 (2004) and Amendment 2 (2006). It constitutes a technical revision.
The principal changes in this edition as compared with the fifth edition of IEC 60335-2-4 are
as follows (minor changes are not listed):
– aligns the text with IEC 60335-1:2001, and its Amendments 1 and 2;
– clarifies criteria for the protection against mechanical hazards for double lid appliances
(20.103 and 20.104);
– some notes have been converted to normative text (Clause 1, 20.102 and Annex AA).

– 4 – 60335-2-4 © IEC:2008
The text of this standard is based on the following documents:
FDIS Report on voting
61/3677/FDIS 61/3697/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.
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 spin extractors.
NOTE 2 The following annex contain provisions suitably modified from another IEC standard:
Annex AA Rinsing agent IEC 60436
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 3 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 4 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.
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.
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the maintenance result 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

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 which 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.

SAFETY –
Part 2-4: Particular requirements for spin extractors

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of
– stand alone electric spin extractors, and
– spin extractors incorporated in washing machines that have separate containers for
washing and spin extraction
for household and similar purposes that have a capacity not exceeding 10 kg of dry cloth and
a drum peripheral speed not exceeding 50 m/s, their rated voltages being not more than
250 V for single-phase appliances and 480 V for other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as spin extractors intended to be used by laymen in shops, in light
industry and on farms, and spin extractors for communal use in blocks of flats or in
launderettes are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances
which 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.
NOTE 101 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 the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
NOTE 102 This standard does not apply to
– appliances intended 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).

Part 2-4: Particular requirements for spin extractors

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 60335-2-4 consists of the sixth edition (2008)
[documents 61/3677/FDIS and 61/3697/RVD] and its amendment 1 (2012) [documents
61/4447/FDIS and 61/4500/RVD]. It bears the edition number 6.1.
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.

– 4 – 60335-2-4  IEC:2008+A1:2012

International Standard IEC 60335-2-4 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.

The principal changes in this edition as compared with the fifth edition of IEC 60335-2-4 are
as follows (minor changes are not listed):

– aligns the text with IEC 60335-1:2001, and its Amendments 1 and 2;

– clarifies criteria for the protection against mechanical hazards for double lid appliances

(20.103 and 20.104);
– some notes have been converted to normative text (Clause 1, 20.102 and Annex AA).

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

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 which 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 2-4: Particular requirements for spin extractors

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of
– stand alone electric spin extractors, and
– spin extractors incorporated in washing machines that have separate containers for
washing and spin extraction
for household and similar purposes that have a capacity not exceeding 10 kg of dry cloth and
a drum peripheral speed not exceeding 50 m/s, their rated voltages being not more than
250 V for single-phase appliances and 480 V for other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as spin extractors intended to be used by laymen in shops, in light
industry and on farms, and spin extractors for communal use in blocks of flats or in
launderettes are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances
which 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.
NOTE 101 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 the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
NOTE 102 This standard does not apply to
– appliances intended 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).

Part 2-4: Particular requirements for spin extractors
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 60335-2-4 edition 6.2 contains the sixth edition (2008-09) [documents 61/3677/FDIS and
61/3697/RVD], its amendment 1 (2012-11) [documents 61/4447/FDIS and 61/4500/RVD] and its
amendment 2 (2017-08) [documents 61/5287/CDV and 61/5373/RVC].

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 which 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 2-4: Particular requirements for spin extractors

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of
– stand alone electric spin extractors, and
– spin extractors incorporated in washing machines that have separate containers for
washing and spin extraction
for household and similar purposes that have a capacity not exceeding 10 kg of dry cloth and
a drum peripheral speed not exceeding 50 m/s, their rated voltages being not more than
250 V for single-phase appliances and 480 V for other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as spin extractors intended to be used by laymen in shops, in light
industry and on farms, and spin extractors for communal use in blocks of flats or in
launderettes are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances
which 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.
NOTE 101 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 the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
NOTE 102 This standard does not apply to
– appliances intended 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).

the most unfavourable way so that the spillage solution also flows over the surface of the
appliance that incorporate controls and other places where it may penetrate the appliance
enclosure, the controls being placed in the on most unfavourable position. The controls are
then operated through their working range, this operation being repeated after a period of 5
min.
+AMD2:2017 CSV  IEC 2017
The appliance shall then withstand the electric strength test of 16.3 and inspection shall show
that there is no trace of water on insulation that could result in a reduction of clearances or

that braking mechanisms and lid interlocks withstand the stresses to which they may be
exposed in normal use.
Compliance is checked by the following test.
The appliance is supplied at 1,06 times rated voltage and operated under normal operation
until the motor has reached its maximum speed.
The lid is then fully opened. The test is repeated after the drum has been at rest for a period
long enough to ensure that the appliance does not attain an excessive temperature.
The test is carried out
– for braking mechanisms:
• 3 500 times for separate spin extractors;
• 1 000 times for spin extractors incorporated in washing machines;
– for lid interlocks, 6 000 times.
The textile material is re-saturated with water at least every 250 times.
After the test, the appliance shall be fit for further use and compliance with this standard shall
not be impaired.
NOTE Forced cooling may be used to prevent excessive temperatures and to shorten the test.

This clause of Part 1 is applicable except as follows.
20.1 Addition:
The drum is empty, or filled as specified for normal operation, whichever is more unfavourable.
20.101 Appliances shall not be adversely affected by an unbalanced load.
Compliance is checked by the following test.
The appliance is placed on a horizontal support and a load having a mass of 0,2 kg or 10 % of
the maximum mass of textile material specified in the instructions, whichever is higher, is
fixed to the inside wall of the drum half-way along its length.
The appliance is supplied at rated voltage and operated for 5 min or the maximum period
allowed by a programmer or timer, whichever is shorter.
The test is carried out four times, the load being moved each time through an angle of 90°
around the wall of the drum.
If compliance relies on the operation of an electronic circuit, the test is repeated with the
fault conditions in a) to g) of 19.11.2 applied one at a time to the electronic circuit.
The appliance shall not overturn and the drum shall not hit other parts except the enclosure.
After the test, the appliance shall be fit for further use.
20.102 The lid or door shall be interlocked so that the appliance can only be operated when
the lid or door is in the closed position.
Compliance is checked by inspection, by manual test and by the following test.
Test probe B of IEC 61032 is applied in order to try and release any interlock that is needed
to comply with the requirement. The interlock shall not release.
20.103 For appliances having a drum with a rotational kinetic energy exceeding 1 500 J, or
– for appliances having a single lid, a maximum peripheral speed exceeding 20 m/s,
– for appliances incorporating two lids, a maximum peripheral speed exceeding 25 m/s,
it shall not be possible to open the lid while the drum is in motion.
Compliance is checked by inspection, by measurement of the maximum peripheral speed, by
calculation of the rotational kinetic energy and by the following test.
The appliance is supplied at rated voltage and operated empty. The force determined during
the test of 22.101 with the lid interlocked is applied to the lid in an attempt to open it.
If compliance relies on the operation of an electronic circuit, the test is repeated under the
following conditions applied separately:
– the fault conditions in a) to g) of 19.11.2 applied one at a time to the electronic circuit;
– the electromagnetic phenomena tests of 19.11.4.1 to 19.11.4.6 applied to the appliance.

In an appliance containing lids or doors that are controlled by one or more interlocks, one of
the interlocks may be released provided that the following conditions are fulfilled:
– the lid or door does not move automatically to an open position when the interlock is
released; and
– the appliance will not restart after the cycle in which the interlock was released.
If the electronic circuit is programmable, the software shall contain measures to control the
fault/error conditions specified in Table R.1 and is evaluated in accordance with the relevant
requirements of Annex R.
20.105 Protective devices fitted in the upper part of spin extractors having a vertical axis
shall be positioned or protected so that the device is not likely to be damaged by textile
material that may escape from the drum in normal use.
Compliance is checked by inspection.
21 Mechanical strength
This clause of Part 1 is applicable except as follows.
21.101 Lids of appliances shall have adequate mechanical strength.
Compliance is checked by the following test.
A rubber hemisphere having a diameter of 70 mm and a hardness between 40 IRHD and
50 IRHD is fixed to a cylinder having a mass of 20 kg and dropped from a height of 100 mm
onto the centre of the lid.
The test is carried out three times, after which the lid shall not be damaged to the extent that
moving parts become accessible.
21.102 Lids and their hinges shall have adequate resistance to distortion.
Compliance is checked by the following test.
A force of 50 N is applied to the open lid in the most unfavourable direction and position.

The test is carried out three times, after which the hinges shall not have worked loose and the
appliance shall not be damaged or deformed to such an extent that compliance with the
appropriate requirements of 20.102 to 20.104 is impaired.
22 Construction
This clause of Part 1 is applicable except as follows.
22.101 Interlocks shall be constructed so that lids or doors are unlikely to be forced open in
normal use.
Compliance is checked by the following test.
The lid or door is opened manually as in normal use, the force applied being measured. The
lid or door is closed and interlocked. An attempt is then made to open the lid or door in the
same way.
It shall not be possible to force open the lid or door with a force less than 10 times the value
originally measured, with a minimum of 50 N.
NOTE The test is not carried out if the interlock is not required for compliance with Clause 20.
