SAFETY OF HOUSEHOLD AND SIMILAR
ELECTRICAL APPLIANCES –
Part 2-11: Particular requirements for tumble dryers
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This fifth edition cancels and replaces the fourth edition published in 1993, amendment 1
(1998) and amendment 2 (1999). This fifth edition constitutes a technical revision.
The text of this standard is based on the fourth edition, amendments 1 and 2 and the
following documents:
FDIS Report on voting
61/1646/FDIS 61/1742/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This part 2 is intended to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the third edition (1991) of that standard.
– 4 – 60335-2-11 © IEC:2000(E)
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert it into the IEC standard: Safety requirements for electric tumble dryers (fourth edition).
Where a particular subclause of part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. Where this standard states "addition", "modification" or "replacement",
the relevant text in part 1 should be adapted accordingly.
NOTE 1 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 2.
NOTE 2 Subclauses and figures which are additional to those in part 1 are numbered starting from 101.
The following differences exist in some countries:
– 2.2.9: Different size cloths are used (USA).
– 6.2: Tumble dryers are not required to be IPX4 (USA).
– 7.1: An instruction concerning cleaning the lint trap is to be marked on the dryer in letters not less than 8 mm
high and is to be conspicuous when the dryer door is open (Australia, New Zealand).
– 7.12: Actual articles of clothing can be specified instead and warnings are required to be marked on the
appliance regarding the use of chemicals for cleaning (USA).
– 11.2: Other methods are used for conducting heating tests on tumble dryers (USA).
– 11.7: This test is continued until steady conditions are established and different criteria are used to determine
when steady conditions are reached (USA).
– 19.4: The test is conducted differently (USA).
– 19.9: A running overload test is required on automatically controlled tumble dryers (USA).
– 20.101: The requirement is applicable to door openings with a dimension exceeding 20 cm (Norway).
– 20.102: When considering accessibility to rotating drums, the maximum drum volume is 60 dm and the
maximum door opening is 20 cm (USA).
– 20.103: This test is not conducted (USA).
– 22.103: Different methods are used to evaluate the stability of stacked tumble dryers and washing machines
(USA).
– 27.1: Earthing terminals and contacts are permitted to be electrically connected to the neutral conductor of a
tumble dryer (USA)
A bilingual version of this standard may be issued at a later date.

SAFETY OF HOUSEHOLD AND SIMILAR
ELECTRICAL APPLIANCES –
Part 2-11: Particular requirements for tumble dryers
1 Scope
This clause of part 1 is replaced by:
This standard deals with the safety of electric tumble dryers intended for household and
similar purposes and having a rated voltage not more than 250 V for single-phase appliances
and 480 V for other appliances.
NOTE 1 This standard applies to the drying function of appliances having both a washing and drying function.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances for communal use in blocks of flats or in laundrettes,
are also within the scope of this standard.
So far as is practicable, this standard deals with the common hazards presented by appliances
which are encountered by all persons in and around the home. However, this standard does not
in general take into account
– the use of appliances by young children or infirm persons without supervision;
– playing with the appliance by young children.
NOTE 2 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;
– For appliances intended to be used in tropical countries, special 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 3 – This standard does not apply to:
– appliances intended exclusively for industrial or commercial purp
