This European Standard was approved by CENELEC on 2005-03-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this EuropeanStandard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained onapplication to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

The text of the International Standard IEC 61121:2002, prepared by SC 59D, Home laundry
appliances, of IEC TC 59, Performance of household electrical appliances, together with the
common modifications prepared by the Technical Committee CENELEC TC 59X, Consumer
information related to household electrical appliances, was submitted to the Unique AcceptanceProcedure (UAP) but did not receive sufficient support.
A new draft, including also the corrigenda April 2003 and September 2003 to IEC 61121:2002,
allowing to maintain the classification of tumble dryers according to the energy label Directive
95/13/EC, was submitted to the formal vote and was approved by CENELEC as EN 61121 on2005-03-01.
Significant technical differences are
a) reference machine in 7.3.2 is neutralized,
b) an addition to Z1.1 describes factors which shall be used to correct the value for the energy
consumption of the appliance found during the test in order to get the correct label value fordeclaration.
This European Standard supersedes EN 61121:1999 and its amendment A11:2000.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-12-01
Annexes ZA and ZB have been added by CENELEC.
Clauses, tables and annexes which are additional to those given in IEC 61121 are prefixed “Z”.__________

The text of the International Standard IEC 61121:2002 + corrigendum April 2003 + corrigendumSeptember 2003 was approved by CENELEC as a European Standard with agreed common
modifications as given below.
Add a fourth paragraph:
This European Standard also specifies, as far as necessary, the test methods which shall be
applied in accordance with the Commission's Directive 95/13/EC of 23 May 1995 implementing
Council Directive 92/75/EEC with regard to energy labelling of household electric tumble dryers
and adds clauses defining permitted tolerances to values declared by the manufacturer and controlprocedures for checking these declared values.
2 Normative references
NOTE Normative references to International Standards are listed in Annex ZB (normative).5 Rated capacity
Add as first paragraph:
The rated capacity for measurements to determine values to be declared for the dry cotton cycle
according to the Commission’s Directive in Clause 1, is the value declared by the manufacturer as
highest amount of cotton textiles to be dried, given in the instruction manual or on the energy labelsupplied with the machine, whatever is higher.
6 General conditions for measurements
Replace 6.1 by:
The measurements shall be carried out on a tumble dryer installed and used in accordance withthe manufacturer's instructions, except as required by this standard.
For the purpose of energy labelling only those test methods are applicable which are requiredaccording to the Commission’s Directive mentioned in Clause 1.
If there is more than one option for installation, the one chosen for testing shall be reported.
For the purpose of energy labelling according to the Commission directive mentioned in Clause 1,the measurements shall be carried out on a new machine.

EN 61121:2005 – 4 –
Where the tumble dryer is intended for use without a duct (i.e. the tumble dryer is intended to be
vented into the room), the tumble dryer shall be tested as supplied without a duct.
Where the tumble dryer is intended for use with a duct and the duct is supplied with the tumble
dryer (i.e. not as a separate accessory), the tumble dryer is tested with this duct, placed in a
configuration consisting of three right angle bends as in Figure A.2, as far as possible.
Where the tumble dryer is intended for use with a duct and the duct is not supplied with the
tumble dryer, the tumble dryer shall be tested with a duct as specified in Annex A.
Where a manufacturer gives the option to use the tumble dryer both with and without a duct, thetumble dryer shall be tested without a duct.
The test report shall clearly state which duct configuration, if any, is used in each test.6.2.1 Electrical supply
Replace the text by:
The supply voltage shall be maintained at 230 V with a relative tolerance of ± 1 %.
The supply frequency shall be maintained at 50 Hz with a relative tolerance of ± 1 %.6.2.3 Ambient temperature
Replace "(20 ± 2) °C" by "(23 ± 2) °C".
6.2.4 Ambient humidity
Replace "(65 ± 5) %" by "(55 ± 5) %".
Replace the 2 sentence in the 1st paragraph by:
To minimize the influence of ageing of the textiles, the cotton base load shall consist of items that
are well distributed in age for all different parts to give an weighted average age of the loadbetween 30 and 50 test cycles, using the weight per piece as given in Annex B.
An example of how textiles may be exchanged is given in Annex ZA.
Replace the first sentence by:
For normalisation wash the test load in a Wascator reference machine as defined in EN 60456with 15 g/kg of the reference detergent A* in EN 60456.
---------------------- Page: 5 ----------------------
– 5 – EN 61121:2005
Replace the 2 and 3 sentence by:
Conditioning is carried out to define the nominal mass of the textiles.
Three methods could be used alternatively:
1) the textiles are left at least for 15 h in an ambient temperature of (20 ± 2) °C and humidity of
(65 ± 5) % unless the weight of the load has changed by less than 0,5 % for two successivemeasurements. The measurements are carried out at two hour intervals;
2) the textiles shall be hung singly and separately so that air can freely circulate. The load is left in
an ambient temperature of (20 ± 2) °C and relative humidity (65 ± 5) % for a period of not lessthan 15 h;
3) bone dry method.
Add after the fourth paragraph:
For the purpose of the Commission’s Directive as specified in Clause 1, the values of the initialmoisture content are as given in column B of Table 2.
Delete fifth paragraph.
8.9 Ambient humidity
Replace: “18 – 22 °C“ by „as given in 6.2.3“.
Replace in the note “12” by “12 h”
18.104.22.168 Procedure for automatic dryer
Add the following sentence as the last sentence in 9.2.1
