international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.

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.

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.
NOTE 103 Attention is drawn to the fact that

– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
– in many countries, additional requirements are specified by the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities, the national
authorities responsible for transportation and the national authorities for buildings.
NOTE 104 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

Part 2-11: Particular requirements for tumble dryers
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This consolidated version of the official IEC Standard and its amendments has been prepared
for user convenience.
IEC 60335-2-11 edition 7.2 contains the seventh edition (2008-07) [documents 61/3646/FDIS and
61/3686/RVD], its amendment 1 (2012-10) [documents 61/4434/FDIS and 61/4493/RVD] and its
amendment 2 (2015-11) [documents 61/5002/FDIS and 61/5056/RVD].
In this Redline version, a vertical line in the margin shows where the technical content is
modified by amendments 1 and 2. Additions are in green text, deletions are in strikethrough red
text. A separate Final version with all changes accepted is available in this publication.

+AMD2:2015 CSV  IEC 2015
International Standard IEC 60335-2-11 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
The principal changes in this edition as compared with the sixth edition of IEC 60335-2-11 are
as follows (minor changes are not listed):
– aligns the text with IEC 60335-1, Ed 4, and its Amendments 1 and 2;
– some notes have been converted to normative text (7.101, 11.8, 20.102, 20.103 and
Annex AA).
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fourth edition (2001) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert that publication into the IEC standard: Safety requirements for electric tumble dryers.
NOTE 2 The following annexes contain provisions suitably modified from other IEC standards:
Annex AA Rinsing agent IEC 60436
Annex BB
Tumble dryers that use a refrigerating system incorporating sealed IEC 60068-2-6 and
motor-compressors for carrying out the drying process IEC 60079-15
Annex CC Non-sparking “n” electrical apparatus IEC 60079-15
Equipment protection by type of protection "n"
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. When this standard states "addition", "modification" or "replacement",
the relevant text in Part 1 is to be adapted accordingly.
NOTE 3 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 4 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
NOTE 5 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.
The following differences exist in the countries indicated below.
– 3.1.9: The textile material has different dimensions (USA).

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features which impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

SAFETY –
Part 2-11: Particular requirements for tumble dryers

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric tumble dryers intended for
household and similar purposes, their rated voltage being not more than 250 V for single-
phase appliances and 480 V for other appliances.
NOTE 101 This standard applies to the drying function of washing machines having a drying cycle.
This standard also deals with the safety of tumble dryers that use a refrigerating system,
incorporating sealed motor-compressors, for drying textile material. These appliances may
use flammable refrigerants. Additional requirements for these appliances are given in
Annex BB.
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 tumble dryers for communal use in blocks of flats or in launderettes.
As far as is practicable, this standard deals with the common 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.
NOTE 103 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
– in many countries, additional requirements are specified by the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities, the national
authorities responsible for transportation and the national authorities for buildings.
NOTE 104 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).

13 Leakage current and electric strength at operating temperature
This clause of Part 1 is applicable except as follows.
13.2 Modification:
For stationary class I appliances, the leakage current shall not exceed 3,5 mA, or 1 mA/kW
rated power input with a limit of 5 mA, whichever is higher.
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 Modification:
The test is carried out with the drum filled with wet textile material as specified for normal
operation, the mass of the water, however, being approximately 1,5 times the mass of the dry
textile material.
Appliances intended to be connected to the water mains are operated with the outlet of the
condensation circuit blocked. The inlet valve is held open and the filling continued for 1 min
after first evidence of overflow or for 5 min after a protective device operates to stop the
flow. Doors are opened but interlocks are not forced.
For all appliances, 0,5 l of water containing approximately 1 % NaCl and 0,6 % of rinsing
agent, as specified in Annex AA, is poured over the top of the appliance, the controls being
placed in the on position. The controls are then operated through their working range, this
operation being repeated after a period of 5 min.
The appliance shall then withstand the electric strength test of 16.3 and inspection shall show
that there is no trace of water on insulation that could result in a reduction of clearances or
creepage distances below the values specified in Clause 29.
16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.
16.2 Modification:
For stationary class I combined appliances, the leakage current shall not exceed 1 mA, or
1 mA/kW rated power input with a limit of 5 mA, whichever is higher.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.

18 Endurance
This clause of Part 1 is not applicable.
19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Modification:
Instead of being subjected to the tests of 19.2 and 19.3, appliances are subjected to the tests
of 19.101 and 19.102, as applicable.
Addition:
If operation without water is a more unfavourable condition for appliances connected to the
water mains, the tests are carried out with the water valve closed. This valve is not closed
after the appliance has started to operate.
19.4 Replacement:
The appliance is operated under the conditions specified in Clause 11 but with dry textile
material. Controls that limit the temperature during the test of Clause 11 and all self-resetting
thermal cut-outs that protect the heating elements are short-circuited simultaneously. The
test is terminated at the end of the maximum period allowed by a timer.
For condensation-type tumble dryers, the test is repeated, but with 75 % of the air outlet of
the condenser blocked. The test is then carried out again with the air outlet fully blocked.
19.9 Not applicable. Addition:
The running overload test is carried out on appliances that have overload protective devices
incorporating electronic circuits to protect the windings of the drum motor. However the test is
not carried out if the protective device senses the winding temperature directly.
19.13 Addition:
The textile material shall not ignite and shall show no charring or glowing.
NOTE 101 Light-brown colouring of the textile material or slight emission of smoke is ignored.
19.101 The appliance is operated under the conditions specified in Clause 11 but with dry
textile material and the drum belt removed. The duration of the test is 90 min or for the
maximum period allowed by a timer.
If air circulation is likely to be prevented due to a fault condition, the test is repeated but with
the drum belt in position and with the air circulation stopped.
NOTE Care should to be taken to ensure that the textile material is tumbling properly by reducing the load if
necessary.
If both of these conditions are likely to occur simultaneously, the tests are combined.
19.102 Appliances that permit test probe C of IEC 61032 to gain access to spaces
containing live parts located below holes in the drum are tested for short circuit conditions.
The short circuit is applied at the most unfavourable place between live parts and between

– 16 – IEC 60335-2-11:2008+AMD1:2012
+AMD2:2015 CSV  IEC 2015
live parts and other metal parts, if such a short circuit can be made by a pin having a
diameter of approximately 1 mm and any length up to 50 mm. The appliance is operated as
specified in Clause 11 but with dry textile material.
19.103 There shall be no risk of fire due to textile material coming into contact with a lamp
cover.
Compliance is checked by the following

Part 2-11: Particular requirements for tumble dryers

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its

provisions is entrusted to appropriately qualified and experienced persons.

This standard recognizes the internationally accepted level of protection against hazards such

as electrical, mechanical, thermal, fire and radiation of appliances when operated as in

normal use taking into account the manufacturer's instructions. It also covers abnormal

situations that can be expected in practice and takes into account the way in which

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features which impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

As far as is practicable, this standard deals with the common 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.
NOTE 103 Attention is drawn to the fact that

– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
– in many countries, additional requirements are specified by the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities, the national
authorities responsible for transportation and the national authorities for buildings.
NOTE 104 This standard does not apply to
– appliances intended exclusively for industrial purposes;
– appliances intended to be used in locations where special conditions prevail, such as the presence of a
corrosive or explosive atmosphere (dust, vapour or gas).

The locking means and its components shall be fit for further use.

NOTE The door is opened and closed during the test if this is necessary for the mechanical operation of the
interlock.
20.102 For appliances with a door opening having a dimension exceeding 200 mm and a
drum having a volume exceeding 60 dm , it shall be possible to open the door from the inside

with a force not exceeding 70 N.

This requirement does not apply to washing machines having a drying function.

Compliance is checked by inspection, by measurement and by applying a force of 70 N
perpendicular to the plane of the door at a point furthest from the hinges.
If the appliance is supplied with a decorative door, the test is carried out with this door closed.
NOTE The force may be applied to the outside of the door.
20.103 Appliances with horizontally hinged doors shall have adequate stability when the
open door is subjected to a load. This requirement is not applicable to built-in appliances.

200 mm and a drum having a volume exceeding 60 dm , it shall not be possible to start the
drum motor after closing the door until a separate means which controls the movement of the
drum is operated manually.
NOTE The volume can be calculated from the maximum depth and the maximum inner diameter of the drum.
Compliance is checked by the following test.
The appliance is supplied at rated voltage, and the door is opened and then closed.
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 are applied one at a time to the electronic
circuit;
– the electromagnetic phenomena tests of 19.11.4.2 and 19.11.4.5 are applied to the
appliance.
