Foreword
This document (EN 61121:2013) consists of the text of IEC 61121:2012 prepared by IEC/SC 59D "Home
laundry appliances" of IEC/TC 59 "Performance of household and similar electrical appliances", together with
the common modifications prepared by CLC/TC 59X "Performance of household and similar electrical
appliances".
The following dates are fixed:
(dop) 2013-12-31
• latest date by which this document has to be implemented
at national level by publication of an identical
national standard or by endorsement
(dow) 2015-12-31
• latest date by which the national standards conflicting
with this document have to be withdrawn

This document supersedes EN 61121:2005.
a) a test procedure for a combined test sequence of full and partial load was introduced;
b) a test procedure for measuring power consumption in low power modes is introduced;
c) a formula to calculate the energy consumption of tumble dryers including low power modes was added;
d) control procedures for checking measured values in comparison to values declared by the manufacturer
under consideration of permitted tolerances are updated.
Clauses, subclauses, notes, tables and figures which are additional to those in IEC 61121:2012 are
prefixed “Z”.
Words in bold in the text are defined in Clause 3.
This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
This European Standard specifies, as far as necessary, the test methods which shall be applied in
accordance with the COMMISSION DELEGATED REGULATION (EU) No 392/2012 implementing Directive
2010/30/EU the European Parliament and of the Council with regard to energy labelling of household tumble
dryers and in accordance with the COMMISSION REGULATION (EU) No 932/2012 implementing Directive
2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for
household tumble dryers.
The procedures described in this European Standard were modified substantially compared to the previous
version, e.g. with regard to partial load. Therefore, results of tests according to this standard cannot and
shall not be directly compared to results of similar procedures of previous versions. In addition, results based
on a specific reference programme shall not be compared to results based on other reference programs.
Annex ZA sets out the procedure to be applied for testing according to Commission Regulations with regard
to energy labelling and ecodesign and provides all necessary links to all relevant clauses of this European
Standard.
– 3 – EN 61121:2013
Annex ZB provides control procedures for checking measured values in comparison to values declared by
the manufacturer under consideration of permitted tolerances.
Annex ZC lists normative references.

4 Requirements
4.1 General
Replace the first paragraph by:
This European Standard does not specify minimum performance requirements for tumble dryers. However,
tumble dryers have to be able to achieve valid test runs and valid test series with final moisture content
values that are in the allowable ranges as set out on Table 6. This European Standard does however set
methods for the measurement of following performance parameters:
5 Test conditions, materials, equipment and instrumentation
5.2.1 Electricity supply
Replace the first two paragraphs by:
The supply voltage shall be maintained throughout the test at 230 V ± 1 % or at 400 V ± 1 % as defined by
the manufacturer’s installation guide. If more than one option for installation is available and no clear
indication for testing is given, the supply voltage shall be 230 V ± 1 %. The supply voltage measured during
the tests shall be recorded.
NOTE In case of a fixed cable, the plug (or the end of the cable) is the reference point to maintain the voltage.
The supply frequency shall be maintained at 50 Hz ± 1 %.
5.2.2.4 Water hardness
Replace by:
Hard water with a total hardness of (2,5 ± 0,2) mmol/l according to EN 60734 shall be used. If available,
naturally occurring water of the correct total hardness and, if applicable, the correct pH, alkalinity and
conductivity may be used. Alternatively, water of the correct total hardness shall be prepared according to
EN 60734.
The total hardness of the water used shall be reported.
The pH, alkalinity and conductivity of the water used to wet the load shall be reported.

Add a second paragraph:
Before each test series the filters, heat exchangers and ducts intended to be serviced by the consumer shall
be cleaned according to the manufacturer’s instructions.
6.4 Preparation of the tumble dryer for a test run
Replace the first paragraph by:
Before each test run the filters, heat exchangers and ducts intended to be serviced by the consumer shall be
cleaned according to the manufacturer’s instructions.
The manufacturer’s specification for the frequency of cleaning of the heat exchanger and related filters
shall be followed. If no specification is given regarding frequency, or the specified frequency is greater than
six cycles then the heat excha
