Household and similar electrical appliances - Safety - Part 2-7: Particular requirements for washing machines
IEC 60335-2-7:2019 deals with the safety of electric washing machines for household and similar use, that are intended for washing clothes and textiles, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. This standard also deals with the safety of electric washing machines for household and similar use employing an electrolyte instead of detergent. Additional requirements for these appliances are given in Annex CC. Guidance is given in Annex DD for requirements that can be used to ensure an acceptable level of protection against electrical and thermal hazards for washing machines fitted with a power driven wringer. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.
Examples of such appliances are washing machines for communal use in blocks of flats or in launderettes. As far as is practicable, this standard deals with the common hazards presented by washing machines 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 washing machines intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;
– in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
This standard does not apply to:
– washing machines intended exclusively for industrial purposes (ISO 10472-2);
– 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);
– washing machines incorporating steam generating devices in which steam is produced at a pressure exceeding 50 kPa.
This eighth edition cancels and replaces the seventh edition published in 2008, Amendment 1: 2011 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
– requirements for steam generators in 3.1.9, 3.6.101, 19.101, 22.106, 22.107;
– additional definitions for washing machine types in 3.5.101,3.5.102, 3.5.103;
– revised temperature limits for external accessible surfaces in 11.3 and 11.8;
– revised test procedure for the spillage test in 15.2;
– additional requirements for appliances that are controlled by programmable electronic circuits that limit the number of heating elements and motors from being energised at the same time, Subclause 22.108.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (2010) of that standard.
Appareils électrodomestiques et analogues - Sécurité - Partie 2-7: Exigences particulières pour les machines à laver le linge
L'IEC 60335-2-7:2019 traite de la sécurité des machines à laver le linge électriques pour usages domestiques et analogues destinées à laver des vêtements et des textiles, dont la tension assignée n'est pas supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils. La présente norme traite également de la sécurité des machines à laver le linge électriques pour usages domestiques et analogues employant un électrolyte à la place d’un détergent. Les exigences complémentaires pour ces appareils sont données à l’Annexe CC. Des recommandations sont données à l’Annexe DD pour les exigences qui peuvent être utilisées pour assurer un niveau acceptable de protection contre les dangers électriques et thermiques pour les machines à laver le linge comportant une essoreuse à rouleaux entraînés par moteur. Les appareils qui ne sont pas destinés à un usage domestique normal mais qui peuvent néanmoins constituer une source de danger pour le public, tels les appareils destinés à être utilisés par des utilisateurs non avertis dans des magasins, chez des artisans et dans des fermes, sont compris dans le domaine d'application de la présente norme. Les machines à laver le linge mises à la disposition commune des utilisateurs dans des immeubles d'habitation ou dans les laveries automatiques sont des exemples de tels appareils. Dans la mesure du possible, la présente norme traite des dangers ordinaires présentés par les machines à laver le linge qui sont encourus par tous les individus à l'intérieur et autour de l'habitation. Cependant, la présente 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 machines à laver le linge destinées à être utilisées 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 machines à laver le linge prévues exclusivement pour des usages industriels (ISO 10472-2);
– aux appareils destinés à être utilisés dans des locaux présentant des conditions particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière, vapeur ou gaz);
– aux machines à laver le linge équipées de dispositifs générant de la vapeur qui est produite à une pression dépassant 50 kPa.
Cette huitième édition annule et remplace la septième édition parue en 2008, l'Amendement 1:2001 et l'Amendement 2:2016. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
– exigences relatives aux générateurs de vapeur, en 3.1.9, 3.6.101, 19.101, 22.106 et 22.107;
– définitions supplémentaires concernant les types de machines à laver le linge, en 3.5.101, 3.5.102 et 3.5.103;
– révision des limites de température pour les surfaces accessibles externes, en 11.3 et 11.8;
– révision de la procédure de l’essai de débordement, en 15.2;
– exigences supplémentaires relatives aux appareils commandés par des circuits électroniques programmables qui limitent le nombre d’éléments chauffants et de moteurs alimentés simultanément, en 22.108. La présente partie 2 doit être utilisée conjointement avec la dernière édition de l’IEC 60335-1 et ses amendements. Elle a été établie sur la base de la cinquième édition (2010) de cette norme.

Part 2-7: Particular requirements for washing machines
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. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.
International Standard IEC 60335-2-7 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This eighth edition cancels and replaces the seventh edition published in 2008,
Amendment 1: 2011 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– requirements for steam generators in 3.1.9, 3.6.101, 19.101, 22.106, 22.107;
– additional definitions for washing machine types in 3.5.101,3.5.102, 3.5.103;
– revised temperature limits for external accessible surfaces in 11.3 and 11.8;
– revised test procedure for the spillage test in 15.2;
– additional requirements for appliances that are controlled by programmable electronic
circuits that limit the number of heating elements and motors from being energised at the
same time, Subclause 22.108.
The text of this International Standard is based on the following documents:
FDIS Report on voting
61/5798/FDIS 61/5839/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.
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 latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fifth edition (2010) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.

IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.
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.
NOTE 1 For example, if appliances within the scope of this Part 2
– have a separate spin container for water extraction, IEC 60335-2-4 is also applicable as far as is reasonable;
– have a drying function, IEC 60335-2-11 is also applicable is applicable as far as is reasonable.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 21 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 32 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 that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

SAFETY –
Part 2-7: Particular requirements for washing machines
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric washing machines for household
and similar use, that are intended for washing clothes and textiles, their rated voltage being
not more than 250 V for single-phase appliances and 480 V for other appliances.
This standard also deals with the safety of electric washing machines for household and
similar use employing an electrolyte instead of detergent. Additional requirements for these
appliances are given in Annex CC.
NOTE 101 Guidance is given in Annex DD for requirements that may can be used to ensure an acceptable level
of protection against electrical and thermal hazards for washing machines fitted with a power driven wringer.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used by laymen in shops, in light
industry and on farms, are within the scope of this standard.
NOTE 102 Examples of such appliances are washing machines for communal use in blocks of flats or in
launderettes.
As far as is practicable, this standard deals with the common hazards presented by washing
machines 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.
NOTE 103 Attention is drawn to the fact that
– for washing machines intended to be used in vehicles or on board ships or aircraft, additional requirements
may be necessary;
– in many countries additional requirements are specified by the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities and similar
authorities.
NOTE 104 This standard does not apply to
– washing machines intended exclusively for industrial purposes (ISO 10472-2);
– 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);
– washing machines incorporating steam generating devices in which steam is produced at a pressure
exceeding 50 kPa.

3.1.9
normal operation
operation of the appliance under the following conditions.
The appliance is filled with dry textile material having a mass equal to the maximum mass
stated in the instructions, and with the maximum quantity of water for which it is constructed.
However, if the power input or current is higher when only 50 % of the textile material is used,
the appliance is operated with this load instead if this gives more unfavourable conditions
than the full load during the test of Clause 11.
Note 101 to entry: For some appliances incorporating a programmer, using the 50 % reduced load may result in
automatic selection of a reduced wash programme.
The temperature of the water is
• 65 C ± 5 °C for appliances without heating elements;
• 15 °C ± 5 °C for appliances without heating elements and intended for connection to the
cold water supply only;
• 15 °C ± 5 °C for other appliances.
If the appliance does not incorporate a programmer, the water is heated to 90 °C ± 5 °C or as
high as the construction will allow if lower, before starting the first washing period.
The textile material consists of pre-washed double-hemmed cotton sheets having dimensions
2 2
approximately 700 mm × 700 mm and a specific mass between 140 g/m and 175 g/m in the
dry condition.
For impeller type washing machines, if the textile material does not move properly during
operation,
• the quantity of textile material may be reduced until the maximum power input of the motor
is attained; or
• a textile material comprising pre-washed double-hemmed cotton sheets, having
dimensions of approximately 900 mm × 900 mm and a mass between 90 g/m and
110 g/m in the dry condition, may be used.

water extraction, spinning or braking, during which the current is the highest.
11 Heating
This clause of Part 1 is applicable except as follows.
11.3 Addition:
Where the external accessible surfaces are suitably flat and access permits, then the test
probe of Figure 101 may be 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:
Appliances incorporating a programmer are operated for three cycles with the programme that
results in highest temperature rises, with a rest period of 4 min between cycles.
Other appliances are operated for three cycles, with a rest period of 4 min between cycles.
Each cycle consists of the following operations:
– for appliances without means for water washing;

material to be dried in the drum, an additional rest period of 4 min
before each drying period. In this case
only two cycles of operation are
carried out.
For appliances incorporating a timer, the washing period, the water extraction period and the
drying period are equal to the maximum period allowed by the timer.
For appliances without a timer,
– the washing period has a duration of
• 6 min, for impeller washing machines of the continuously rotating impeller type;
• 18 min, for agitator washing machines of the agitator type;
• 25 min for drum washing machines of the drum type, unless a longer period is stated
in the instructions;
– the water extraction period has a duration of 5 min.
The rest period, including any braking time, has a duration of 4 min.
After the specified sequence of operation, discharge pumps that are driven by a separate
motor and switched on and off manually, are subjected to three operating periods separated
by rest periods of 4 min. Each operating period is equal to 1,5 times the period necessary to
empty the appliance when filled to the maximum normal water level. The outlet of the water
discharge pipe is 900 mm above the floor.

Compliance is checked by the following test that is carried out immediately after that of 15.2.
The appliance is operated under the conditions specified in Clause 11 but at rated voltage for
one complete cycle with the programme that results in the longest period of operation. Twice
the A quantity of detergent necessary for normal washing to cause foaming is added. The
composition of the detergent is specified in Annex AA.
For appliances incorporating a detergent dispenser, the solution is added manually at the
point in the cycle when it would normally be dispensed automatically. For other appliances,
the solution is added before starting the cycle.
The appliance shall then withstand the electric strength test of 16.3.
The appliance is kept in a test room having a normal atmosphere for 24 h before being
subjected to the test of 15.3.
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.
18.101 Appliances shall be constructed so that the lid or door interlock withstands the
stresses to which it may be exposed in normal use.
Compliance is checked by the following test.
The lid or door is opened as in normal use and the force applied to the handle, or actuating
means of the release mechanism, is measured. The force required to close the lid or door is
also measured.
The lid or door is then subjected to 10 000 cycles of opening and closing. For the first
6 000 cycles, the appliance is supplied at rated voltage and operated so that the interlock
mechanism is energized and de-energized each cycle. For the last 4 000 cycles, the
appliance is not connected to the supply mains. For appliances having a drying function, the
total number of cycles is increased to 13 000, the first 9 000 cycles being carried out with the
interlock mechanism energized and de-energized each cycle.
If the interlock complies with IEC 60730-2-12, the appliance is not connected to the supply
mains during this test. If the interlock operates more than once during normal operation, it is
operated for this number of times during each cycle.
Lids are opened each time by approximately 45° and doors by 90°, the speed of opening
being approximately 1,5 m/s. The force applied to open the lid or door is twice the measured
opening force, with a minimum of 50 N and a maximum of 200 N.
Doors are closed at a speed of approximately 1,5 m/s, the force applied being five times the
measured closing force, with a minimum of 50 N and a maximum of 200 N. Lids are allowed to
close under their own weight but if they fail to latch, a force of five times the measured closing
force is applied, with a minimum of 50 N and a maximum of 200 N.
After the tests, compliance with the relevant requirements of 20.103 to 20.105 shall not be
impaired.
18.102 The braking mechanism of appliances having a lid that can be opened during the
water extraction period shall withstand the stresses to which they may be exposed in normal
use.
Compliance is checked by the following test.
The appliance is supplied at 1,06 times rated voltage and operated under normal operation
until the motor has reached its highest 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 1 000 times, the textile material being re-saturated with water at least
every 250 times.
After the test, the appliance shall be fit for further use and compliance with this standard shall
not be impaired.
NOTE Forced cooling may 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.
19.1 Addition:
For appliances incorporating a programmer or a timer, the tests of 19.2 and 19.3 are replaced
by the test of 19.101.
The test of 19.7 is not carried out on motors driving moving parts of an oscillating agitator.
Appliances not intended for connection to the hot water supply and not provided with heating
elements are also subjected to the test of 19.102.
19.2 Addition:
Restricted heat dissipation is obtained without water in the appliance or with just sufficient
water to cover the heating elements, whichever is the more unfavourable.
19.7 Addition:
Appliances without a programmer or timer are operated for 5 min.
19.9 Not applicable
Addition:
The running overload test is carried out

Part 2-7: Particular requirements for washing machines
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 60335-2-7 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This eighth edition cancels and replaces the seventh edition published in 2008,
Amendment 1: 2011 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– requirements for steam generators in 3.1.9, 3.6.101, 19.101, 22.106, 22.107;
– additional definitions for washing machine types in 3.5.101,3.5.102, 3.5.103;
– revised temperature limits for external accessible surfaces in 11.3 and 11.8;
– revised test procedure for the spillage test in 15.2;
– additional requirements for appliances that are controlled by programmable electronic
circuits that limit the number of heating elements and motors from being energised at the
same time, Subclause 22.108.
The text of this International Standard is based on the following documents:
FDIS Report on voting
61/5798/FDIS 61/5839/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.
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 latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fifth edition (2010) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert that publication into the IEC standard: Safety requirements for washing machines.
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
• amended.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip 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.
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 that 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 2-7: Particular requirements for washing machines
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric washing machines for household
and similar use, that are intended for washing clothes and textiles, their rated voltage being
not more than 250 V for single-phase appliances and 480 V for other appliances.
This standard also deals with the safety of electric washing machines for household and
similar use employing an electrolyte instead of detergent. Additional requirements for these
appliances are given in Annex CC.
NOTE 101 Guidance is given in Annex DD for requirements that can be used to ensure an acceptable level of
protection against electrical and thermal hazards for washing machines fitted with a power driven wringer.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used by laymen in shops, in light
industry and on farms, are within the scope of this standard.
NOTE 102 Examples of such appliances are washing machines for communal use in blocks of flats or in
launderettes.
As far as is practicable, this standard deals with the common hazards presented by washing
machines 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.
NOTE 103 Attention is drawn to the fact that
– for washing machines intended to be used in vehicles or on board ships or aircraft, additional requirements
may be necessary;
– in many countries additional requirements are specified by the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities and similar

operation of the appliance under the following conditions.
The appliance is filled with dry textile material having a mass equal to the maximum mass
stated in the instructions, and with the maximum quantity of water for which it is constructed.
However, if the power input or current is higher when only 50 % of the textile material is used,
the appliance is operated with this load instead if this gives more unfavourable conditions
than the full load during the test of Clause 11.
Note 101 to entry: For some appliances incorporating a programmer, using the 50 % reduced load may result in
automatic selection of a reduced wash programme.
The temperature of the water is
• 65 C ± 5 °C for appliances without heating elements;
• 15 °C ± 5 °C for appliances without heating elements and intended for connection to the
cold water supply only;
• 15 °C ± 5 °C for other appliances.
If the appliance does not incorporate a programmer, the water is heated to 90 °C ± 5 °C or as
high as the construction will allow if lower, before starting the first washing period.
The textile material consists of pre-washed double-hemmed cotton sheets having dimensions
2 2
approximately 700 mm × 700 mm and a specific mass between 140 g/m and 175 g/m in the
dry condition.
For impeller washing machines, if the textile material does not move properly during
operation,
• the quantity of textile material may be reduced until the maximum power input of the motor
is attained; or
• a textile material comprising pre-washed double-hemmed cotton sheets, having
dimensions of approximately 900 mm × 900 mm and a mass between 90 g/m and
110 g/m in the dry condition, may be used.
However, for impeller washing machines, in case of doubt, the test is carried out using the
reduced quantity of textile material.

Appliances with type X attachment, except those having a specially prepared cord, are fitted
with the lightest permissible type of flexible cord of the smallest cross-sectional area specified
in Table 13.
Appliances intended to be filled with water by the user are completely filled with water
containing approximately 1 % NaCl. A further quantity of this solution equal to 15 % of the
capacity of the appliance or 0,25 l, whichever is greater, is poured in steadily over a period of
1 min.
Other appliances are operated until the maximum water level is reached, and 5 g of the
detergent specified in Annex AA is added for each litre of water in the appliance. Each inlet
valve is held open and the filling is continued for 15 min after first evidence of overflow or until
the inflow is automatically stopped by other means. The appropriate tests being applied one

Compliance is checked by the following test that is carried out immediately after that of 15.2.
The appliance is operated under the conditions specified in Clause 11 but at rated voltage for
one complete cycle with the programme that results in the longest period of operation. A
quantity of detergent necessary to cause foaming is added. The composition of the detergent
is specified in Annex AA.
For appliances incorporating a detergent dispenser, the solution is added manually at the
point in the cycle when it would normally be dispensed automatically. For other appliances,
the solution is added before starting the cycle.
The appliance shall then withstand the electric strength test of 16.3.
The appliance is kept in a test room having a normal atmosphere for 24 h before being
subjected to the test of 15.3.
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.
18.101 Appliances shall be constructed so that the lid or door interlock withstands the
stresses to which it may be exposed in normal use.
Compliance is checked by the following test.
The lid or door is opened as in normal use and the force applied to the handle, or actuating
means of the release mechanism, is measured. The force required to close the lid or door is
also measured.
The lid or door is then subjected to 10 000 cycles of opening and closing. For the first
6 000 cycles, the appliance is supplied at rated voltage and operated so that the interlock
mechanism is energized and de-energized each cycle. For the last 4 000 cycles, the
appliance is not connected to the supply mains. For appliances having a drying function, the
total number of cycles is increased to 13 000, the first 9 000 cycles being carried out with the
interlock mechanism energized and de-energized each cycle.
If the interlock complies with IEC 60730-2-12, the appliance is not connected to the supply
mains during this test. If the interlock operates more than once during normal operation, it is
operated for this number of times during each cycle.
Lids are opened each time by approximately 45° and doors by 90°, the speed of opening
being approximately 1,5 m/s. The force applied to open the lid or door is twice the measured
opening force, with a minimum of 50 N and a maximum of 200 N.
Doors are closed at a speed of approximately 1,5 m/s, the force applied being five times the
measured closing force, with a minimum of 50 N and a maximum of 200 N. Lids are allowed to
close under their own weight but if they fail to latch, a force of five times the measured closing
force is applied, with a minimum of 50 N and a maximum of 200 N.
After the tests, compliance with the relevant requirements of 20.103 to 20.105 shall not be
impaired.
18.102 The braking mechanism of appliances having a lid that can be opened during the
water extraction period shall withstand the stresses to which they may be exposed in normal
use.
Compliance is checked by the following test.
The appliance is supplied at 1,06 times rated voltage and operated under normal operation
until the motor has reached its highest speed. The lid is then fully opened. The test is
repeated after the drum has been at rest for
