IEC 60335-2-4:2023

Household and similar electrical appliances - Safety - Part 2-4: Particular requirements for spin extractors

IEC 60335-2-4:2023 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 including direct current (DC) supplied appliances and battery-operated appliances.
Appliances not intended for normal household use but which nevertheless can 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 reasonably foreseeable hazards presented by appliances that are encountered by all persons. 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.
Attention is drawn to the fact that:
- for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can 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.
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).
This eighth edition cancels and replaces the seventh edition published in 2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) alignment with IEC 60335-1:2020;

- des enfants qui jouent avec l'appareil.
L'attention est attirée sur le fait que:
- pour les appareils destinés à être utilisés dans des véhicules ou à bord de navires ou d'avions, des exigences supplémentaires peuvent être nécessaires;
- dans de nombreux pays, des exigences supplémentaires sont spécifiées par les organismes nationaux de la santé, par les organismes nationaux responsables de la protection des travailleurs, par les organismes nationaux responsables de l'alimentation en eau et par des organismes similaires.
La présente norme ne s'applique pas:
- aux appareils prévus exclusivement pour des usages industriels;
- aux appareils destinés à être utilisés dans des locaux qui présentent des conditions particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière, vapeur ou gaz).
Cette huitième édition annule et remplace la septième édition parue en 2021. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) le texte a été aligné sur l'IEC 60335-1:2020;
b) certaines notes ont été converties en texte normatif (20.103, 20.104, 22.101);
c) le calibre d'essai 19 a été ajouté pour l'accès aux parties actives et aux parties mobiles (8.1.1, 20.2);
d) des limites de température ont été ajoutées pour les surfaces accessibles (11.3, 11.8);
e) des conditions de fonctionnement ont été spécifiées pour les appareils alimentés par batteries (B.11.1).
La présente partie 2 doit être utilisée conjointement avec la dernière édition de l'IEC 60335-1 et ses amendements sauf si cette édition l'exclut. Dans ce cas, la dernière édition qui n'exclut pas la présente partie 2 est utilisée. Elle a été établie sur la base de la sixième édition (2020) de cette norme.

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) 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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition IEC 60335-2-4:2021. A vertical bar appears in the margin
wherever a change has been made. Additions are in green text, deletions are in
strikethrough red text.
IEC 60335-2-4 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This eighth edition cancels and replaces the seventh edition published in 2021. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) conversion of some notes to normative text (20.103, 20.104, 22.101);
c) addition of test probe 19 for accessibility of live parts and moving parts (8.1.1, 20.2);
d) addition of accessible surface temperature limits (11.3, 11.8);
e) specified operating conditions for battery operated appliances (B.11.1).
The text of this International Standard is based on the following documents:
Draft Report on voting
61/7014/FDIS 61/7078/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/standardsdev/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: Particular requirements for spin extractors.
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.

− 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.
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.
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.

IMPORTANT – The "colour inside" logo on the cover page of this document indicates
that it contains colours which are considered to be useful for the correct understanding

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 supporting documents on the IEC website
https://www.iec.ch/tc61/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 may 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 and generic standards 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. 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.
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.

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 including direct current (DC)
supplied appliances and battery-operated appliances.
Appliances not intended for normal household use but which nevertheless may can 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 reasonably foreseeable 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
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;

11.3 Addition:
Where the external accessible surfaces are suitably flat and access permits, then the test
probe of Figure 101 is used to measure the temperature rises of external accessible surfaces
specified in Table 101. The probe is applied with a force of 4 N ± 1 N to the surface in such a
way that the best possible contact between the probe and the surface is ensured. The
measurement is performed after a contact period of 30 s.
The probe may be held in place using a laboratory stand clamp or similar device. Any measuring
instrument giving the same results as the probe may be used.
11.7 Replacement Modification:
Replace the first paragraph with the following:
Appliances are operated for five periods of water extraction, the periods being separated by a
rest period. Each rest period, which includes the braking time, has a duration of 1 min for each

– 12 – IEC 60335-2-4:2023 RLV © IEC 2023
kilogram of dry textile material or 4 min, whichever is longer. During the rest period, the textile
material is re-saturated with water.
For appliances incorporating a programmer or timer, the water extraction period is the maximum
allowed by the control.
For other appliances, the water extraction period has a duration of:
– 15 min for continuous-flow rinsing appliances;
– 5 min for other appliances.
If a longer period is indicated in the instructions, this period applies instead.
Replace the first dashed item of the third paragraph with the following:
– the battery that has been fully discharged is charged for 1 h, while the appliance is operated
as specified performing its intended function, if allowed by the construction of the appliance.

INTRODUCTION
Edition 6 of IEC 60335-1:2020 defines and introduces requirements for a detachable
power supply part of an appliance. In the document, 24.2 prohibits the use of a power
supply in a flexible cord.
QUESTION:
Does Subclause 24.2 prohibit the use of a detachable power supply part?
ANSWER
No, a "detachable power supply part" is a defined term and is not captured by the term
"power supply" as used in Subclause 24.2.
NOTE A detachable power supply part is captured by the defined term when the output of the power supply
part is detachable from the class III construction part of the appliance at:
– the power supply part, or
– the class III construction part of the appliance.
However, the supply cord (if any) does not have to be detachable from the detachable power supply part.

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.

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 supporting documents on the IEC website
https://www.iec.ch/tc61/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.
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.
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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-4: Particular requirements for spin extractors

1 Scope
This part of IEC 60335 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 including direct current (DC)
supplied appliances and battery-operated appliances.
Appliances not intended for normal household use but which nevertheless can 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 reasonably foreseeable hazards presented
by appliances that are encountered by all persons. 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.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can 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.
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).

INTRODUCTION
Edition 6 of IEC 60335-1:2020 defines and introduces requirements for a detachable
power supply part of an appliance. In the document, 24.2 prohibits the use of a power
supply in a flexible cord.
QUESTION:
Does Subclause 24.2 prohibit the use of a detachable power supply part?
ANSWER
No, a "detachable power supply part" is a defined term and is not captured by the term
"power supply" as used in Subclause 24.2.
NOTE A detachable power supply part is captured by the defined term when the output of the power supply
part is detachable from the class III construction part of the appliance at:
– the power supply part, or
– the class III construction part of the appliance.
However, the supply cord (if any) does not have to be detachable from the detachable power supply part.

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

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/standardsdev/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: Particular requirements for spin extractors.

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 supporting documents on the IEC website
https://www.iec.ch/tc61/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.
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.
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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-4: Particular requirements for spin extractors

1 Scope
This part of IEC 60335 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 including direct current (DC)
supplied appliances and battery-operated appliances.
Appliances not intended for normal household use but which nevertheless can 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 reasonably foreseeable hazards presented
by appliances that are encountered by all persons. 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.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can 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.
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).

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.

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 supporting documents on the IEC website
https://www.iec.ch/tc61/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 may 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 and generic standards 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. 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.
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.

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 part of IEC 60335 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 including direct current (DC)
supplied appliances and battery-operated appliances.
Appliances not intended for normal household use but which nevertheless may can 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 reasonably foreseeable 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
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can 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.
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) 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 60335-2-4 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This eighth edition cancels and replaces the seventh edition published in 2021. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) conversion of some notes to normative text (20.103, 20.104, 22.101);
c) addition of test probe 19 for accessibility of live parts and moving parts (8.1.1, 20.2);
d) addition of accessible surface temperature limits (11.3, 11.8);

e) specified operating conditions for battery operated appliances (B.11.1).
The text of this International Standard is based on the following documents:
Draft Report on voting
61/7014/FDIS 61/7078/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/standardsdev/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: Particular requirements for spin extractors.
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.
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.
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

– 6 – IEC 60335-2-4:2023 © IEC 2023
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.

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 supporting documents on the IEC website
https://www.iec.ch/tc61/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.
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.
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.

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 part of IEC 60335 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 including direct current (DC)
supplied appliances and battery-operated appliances.
Appliances not intended for normal household use but which nevertheless can 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 reasonably foreseeable hazards presented
by appliances that are encountered by all persons. 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.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can 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.
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).

way that the best possible contact between the probe and the surface is ensured. The
measurement is performed after a contact period of 30 s.
The probe may be held in place using a laboratory stand clamp or similar device. Any measuring
instrument giving the same results as the probe may be used.
11.7 Modification:
Replace the first paragraph with the following:
Appliances are operated for five periods of water extraction, the periods being separated by a
rest period. Each rest period, which includes the braking time, has a duration of 1 min for each
kilogram of dry textile material or 4 min, whichever is longer. During the rest period, the textile
material is re-saturated with water.
For appliances incorporating a programmer or timer, the water extraction period is the maximum
allowed by the control.
For other appliances, the water extraction period has a duration of:
– 15 min for continuous-flow rinsing appliances;
– 5 min for other appliances.
If a longer period is indicated in the instructions, this period applies instead.
Replace the first dashed item of the third paragraph with the following:

14 Transient overvoltages
This clause of Part 1 is applicable.
15 Moisture resistance
This clause of Part 1 is applicable except as follows.
15.2 Addition:
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 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 incorporates controls and other places where it can penetrate the appliance enclosure, the
controls being placed in the most unfavourable position. The controls are then operated through
their working range, this operation being repeated after 5 min.
16 Leakage current and electric strength
This clause of Part 1 is applicable.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
18 Endurance
This clause of Part 1 is replaced by the following.
Appliances having lids that can be opened while the drum is rotating shall be constructed so
that braking mechanisms and lid interlocks withstand the stresses to which they can 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 according
to Table 3.
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 101 Forced cooling can be used to prevent excessive temperatures and to shorten the test.
19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.7 Not applicable.

19.9 Not applicable.
20 Stability and mechanical hazards
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.
20.2 Addition:
For parts of appliances situated not more than 850 mm above the floor after installation or in
normal use, in addition to the use of test probe 18, test probe 19 of IEC 61032 is also applied
wherever test probe 18 is used and with the same test conditions used for test probe 18.
Test probe 19 is not applied to appliances for communal use in blocks of flats or in launderettes.
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 with a force of 5 N and test probe 18 of IEC 61032 is
applied with a force of 2,5 N 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.
The tests are carried out with surge protective devices disconnected, unless they
incorporate spark gaps.
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.
It shall not be possible to open the lid while the drum is in motion.
If the drum is not cylindrical, the peripheral speed is the mean peripheral speed.
The rotational kinetic energy is calculated from the following formula:
mv
E=
where
E is the rotational kinetic energy, in J;
m is the mass of the cloth specified in the instructions for use, in kg;
v is the maximum peripheral speed of the drum, in m/s.
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 normative Annex R.
20.104 For appliances having a drum with a rotational kinetic energy not exceeding 1 500 J
and
– for appliances having a single lid, a maximum peripheral speed not exceeding 20 m/s,
– for appliances incorporating two lids, a maximum peripheral speed not exceeding 25 m/s,
moving parts shall not be accessible while the motor is energized or when the drum speed
exceeds 60 r/min.
The braking system shall not be affected by the penetration of water.
Compliance is checked by measurement of the maximum peripheral speed, by calculation of
the rotational kinetic energy in accordance with the formula in 20.103 and by the following test,
which is carried out after repeating the spillage test of 15.2.

The appliance is supplied at rated voltage and operated empty. For appliances having a single
lid and for appliances incorporating two lids where the second lid does not open independently
of the first lid, the lid or first lid as appropriate is gradually opened and
– with an opening of 4 mm to 10 mm, it shall not be possible to touch parts rotating at a speed
exceeding 60 r/min with the test probe 12 of IEC 61032;
– with an opening greater than 10 mm, but not more than 12 mm, it shall not be possible to
touch parts rotating at a speed exceeding 60 r/min with a test rod 3 mm in diameter and
120 mm long. In addition, test probe B of IEC 61032 and test probe 18 of IEC 61032 are
applied and shall not come within a distance of 20 mm from the rotating parts;
– with an opening greater than 12 mm, the motor shall be disconnected from the supply and
within 7 s, the drum speed shall not exceed 60 r/min.
For appliances incorporating two lids where the second lid opens independently of the first lid,
the first lid is gradually opened and with an opening greater than 50 mm, the motor shall be
disconnected from the supply and within 2 s the drum speed shall not exceed 20 m/s.
The second lid is gradually opened and
– with an opening of 4 mm to 10 mm, it shall not be possible to touch parts rotating at a speed
exceeding 60 r/min with the test probe 12 of IEC 61032;
– with an opening greater than 10 mm, but not more than 12 mm, it shall not be possible to
touch parts rotating at a speed exceeding 60 r/min with a test rod 3 mm in diameter and
120 mm long. In addition, test probe B of IEC 61032 and test probe 18 of IEC 61032 are
applied and shall not come within a distance of 20 mm from the rotating parts;
– with an opening greater than 12 mm and within 7 s, the drum speed shall not exceed
60 r/min.
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 19.11.4.2 and 19.11.4.5 applied in turn to the
appliance. The tests are carried out with surge protective devices disconnected, unless they
incorporate spark gaps.
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 normative 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 can escape from the drum in normal use.
Compliance is checked by inspection.
21 Mechanical strength
