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

IEC 60335-2-4:2021 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.
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 seventh edition cancels and replaces the sixth edition published in 2008, Amendment 1:2012 and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- aligns the text with IEC 60335-1, Ed 5, and its Amendments 1 and 2;
- replacement of the term definition of accessible part to include test probe 18;

Appareils électrodomestiques et analogues - Sécurité - Partie 2-4: Exigences particulières pour les essoreuses centrifuges

L'IEC 60335-2-4:2021 traite de la sécurité:
- des essoreuses centrifuges électriques indépendantes, et
- des essoreuses centrifuges incorporées à des machines à laver le linge qui comportent des tambours distincts pour le lavage et l'essorage
pour usages domestiques et analogues dont la capacité ne dépasse pas 10 kg de linge sec, dont la vitesse périphérique du tambour ne dépasse pas 50 m/s et dont la tension assignée n'est pas supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils.
Les appareils non destinés à un usage domestique normal, mais qui peuvent néanmoins constituer une source de danger pour le public, tels que les essoreuses centrifuges destinées à être utilisées par des usagers non avertis dans des magasins, chez des artisans et dans des fermes, ainsi que les essoreuses centrifuges destinées à un usage collectif dans des immeubles d'habitation ou dans des laveries automatiques, relèvent du domaine d'application de la présente norme. Dans la mesure du possible, la présente norme traite des dangers ordinaires présentés par les appareils, encourus par tous les individus situés à l'intérieur et autour de l'habitation. Cependant, cette norme ne tient pas compte en général:
- des personnes (y compris des enfants) dont les capacités physiques, sensorielles ou mentales; ou le manque d'expérience et de connaissance
les empêchent d'utiliser l'appareil en toute sécurité sans surveillance ou instruction;
- de l'utilisation de l'appareil comme jouet par des enfants.
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 autorités sanitaires nationales, les organismes nationaux en charge de la protection des travailleurs, les agences nationales de l'eau et des organismes analogues.
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 édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- alignement du texte sur l'IEC 60335-1, Ed 5 et ses Amendements 1 et 2;
- remplacement de la définition du terme "partie accessible" pour inclure le calibre d'essai 18;
- ajout du calibre d'essai 18 pour l'accès aux parties actives.
La présente partie 2 doit être utilisée conjointement avec l'IEC 60335-1:2010 et ses amendements.

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 redline version of the official IEC Standard allows the user to identify the changes made to

the previous edition IEC 60335-2-4:2008+AMD1:2012+AMD2:2017 CSV. A vertical bar appears in

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 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.
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 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.
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).

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 may 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 may be
exposed in normal use.
Compliance is checked by the following test.

– 12 – IEC 60335-2-4:2021 RLV © IEC 2021

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 101 Forced cooling may 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.

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 61032:1997 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.

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.
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.
NOTE 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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES – SAFETY –

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.
International Standard IEC 60335-2-4 has been prepared by IEC technical committee 61: Safety
of household and similar electrical appliances.
This seventh edition cancels and replaces the sixth edition published in 2008,
Amendment 1:2012 and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– aligns the text with IEC 60335-1, Ed 5, and its Amendments 1 and 2;
– replacement of the term definition of accessible part to include test probe 18;
– addition of test probe 18 for accessibility of live parts.

– 4 – IEC 60335-2-4:2021 © IEC 2021
The text of this International Standard is based on the following documents:

61/6128/FDIS 61/6179/RVD
Full information on the voting for the approval of this International Standard 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 has been drafted in accordance with the ISO/IEC Directives, Part 2.
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 fifth edition of IEC 60335-1:2010 and its
amendments.
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 "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document 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.
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.
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;
