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

Part 2-11: 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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s).
IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect
thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which may
be required to implement this document. However, implementers are cautioned that this may not represent the
latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC shall

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules can differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal publications, basic safety publications and group safety publications covering a hazard are not
applicable since they have been taken into consideration when developing the general and particular requirements
for the IEC 60335 series of standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features which impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with the
standard.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-11: Particular requirements for tumble dryers

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 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 including direct current (DC) supplied appliances.
This standard applies to the drying function of washing machines having a drying cycle.
This standard also deals with the safety of heat pump type tumble dryers. These appliances
may use flammable refrigerants. Additional requirements for these appliances are given in
normative Annex AA.
Appliances not intended for normal household use but which nevertheless can 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 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.
However, in general, it does not take into account
– persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities,
the national authorities responsible for the protection of labour, the national water supply
authorities.
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);
– appliances incorporating steam generating devices in which steam is produced at a pressure
exceeding 50 kPa.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60335-2-11 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This ninth edition cancels and replaces the eighth edition published in 2019. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) conversion of some notes to normative text (Clause 1, Annex AA);
c) implement new definitions to type of appliances (3.5.102, 3.5.103, 3.5.104);
d) specific requirements have been added in 22.51 for remote operation;

e) specific requirements have been added in Clause 24 for motor running capacitors;
f) new modifications in Annex R;
g) update of requirements for appliance that use flammable refrigerants in Clause 21 and
Clause 22 of Annex AA;
h) implement new requirements for non-sparking "n" electrical apparatus in Annex BB.
The text of this International Standard is based on the following documents:
Draft Report on voting
61/7072/FDIS 61/7096/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications.
A list of all parts of the IEC 60335 series, under the general title: Household and similar
electrical appliances – Safety, can be found on the IEC website.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
NOTE 1 When "Part 1" is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to convert
that publication into the IEC standard: Particular requirements for tumble dryers.

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.

The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• 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 can need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 12 months or later than 36 months from the date of publication.

IMPORTANT – The "colour inside" logo on the cover page of this document indicates that it

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules can differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal publications, basic safety publications and group safety publications covering a hazard are not
applicable since they have been taken into consideration when developing the general and particular requirements
for the IEC 60335 series of standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features which impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with the
standard.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

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

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 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 including direct current (DC) supplied appliances.
This standard applies to the drying function of washing machines having a drying cycle.
This standard also deals with the safety of heat pump type tumble dryers. These appliances
may use flammable refrigerants. Additional requirements for these appliances are given in
normative Annex AA.
Appliances not intended for normal household use but which nevertheless can 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 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.
However, in general, it does not take into account
– persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities,
the national authorities responsible for the protection of labour, the national water supply
authorities.
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);
– appliances incorporating steam generating devices in which steam is produced at a pressure
exceeding 50 kPa.

probe of Figure 101 is used to measure the temperature rises of external accessible surfaces
specified in Table 101. The probe is applied with a force of 4 N ± 1 N to the surface in such a
way that the best possible contact between the probe and the surface is ensured. The
measurement is performed after a contact period of 30 s.
The probe may be held in place using a laboratory stand clamp or similar device. Any measuring
instrument giving the same results as the probe may be used.
11.7 Modification:
Replace the first paragraph with the following:
Appliances incorporating a timer, a humidity sensing control or other time-limiting control are
operated in cycles. Each cycle comprises an operating period having a duration equal to the
maximum time that can be provided by the control and a rest period of 4 min during which the
appliance is reloaded.
The test may be ended if the temperature rise of any part does not exceed the value determined
during the preceding cycle by more than 8 K.
Appliances having a combined washing-drying cycle are operated with the drying programme
resulting in the highest temperature rise.
Appliances with a steam generator are operated with that steam mode resulting in the highest
temperature rise.
Other appliances are operated continuously until steady conditions are established.
11.8 Modification:
Replace the first paragraph with the following:
During the test, the temperature rises are monitored continuously and shall not exceed the
values shown in Table 3 and Table 101.

12 Charging of metal-ion batteries
This clause of Part 1 is applicable
13 Leakage current and electric strength at operating temperature
This clause of Part 1 is applicable except as follows.
13.2 Modification:
Replace the last two dashed items in the eighth paragraph with the following:
– for stationary class I appliances 3,5 mA, or 1 mA per kW of rated power input
with a maximum 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 Addition:
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 the spillage solution is rapidly poured over the top of the appliance,
so that the spillage solution flows over the surfaces of the appliance that incorporate controls,
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.

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 adjusted
after the appliance has started to operate.
The steam generator is operated without water.
19.2 Not applicable
19.3 Not applicable
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 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. Care shall be taken to ensure that
the textile material is tumbling properly by reducing the load if necessary.
If both 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 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 test.

Ten layers of cheesecloth are placed over the lamp cover. The appliance is supplied at rated
voltage with the door open until steady conditions are established. The temperature rise of the
cover shall not exceed 150 K.
