(Amendment)Electric clothes washer-dryers for household use - Methods for measuring the performance
Electric clothes washer-dryers for household use - Methods for measuring the performance
IEC 62512:2012 provides a globally applicable and agreed method to test the washing and drying function of washer-dryers. Although this standard is based on IEC 61121:2012 on tumble dryers and IEC 60456:2010 on clothes washers, it specifies the conditions needed to test the combined function of washing and drying. The main elements of this standard are: - the definition of the loads to be tested in continuous and interrupted operation cycles; - the method for testing automatic and not automatic operation of the drying cycles; - the way to handle the load for interrupted operation cycles; - the correction to be applied to test results for continuous and interrupted operation cycles.

European foreword
This document (EN IEC 62512:2020/A11:2020) consists of the text of IEC 62512:2012 prepared by
IEC/SD 59, "Home laundry appliances", together with the common modifications prepared by CLC/TC
59X "Performance of household and similar electrical appliances".
The following dates are fixed:
• latest date by which this document has to be (dop) 2021-07-21
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2023-10-21
conflicting with this document have to be
withdrawn
This document supersedes EN 50229:2015.
Significant technical differences are:
a the definition of the loads to be tested in continuous, segmented and interrupted operation cycles;
b the method for testing automatic and not automatic operation of the drying cycles;
c the way to handle the load for interrupted operation cycles;
d the correction to be applied to test results for continuous and interrupted operation cycles;
e the definition of a procedure for a segmented operation cycle to simulate a continuous wash and
dry cycle, if the machine does not offer those programme setting;
f the test procedure for the performance measurements for multi-drum washer dryers according to
EU energy label regulation.
This document also specifies, as far as necessary, the test method for household washing machines in
accordance with the COMMISSION DELEGATED REGULATION (EU) 2019/2014 of 11 March 2019
supplementing Regulation 2017/1369 of the European Parliament and of the Council with regard to
energy labelling of household washing machines and household washer-dryers and repealing
Commission Regulation (EU) No 1061/2010 and Commission Directive 96/60/EC and in accordance
with the COMMISSION REGULATION (EU) 2019/2023 of 1 October 2019 laying down ecodesign
requirements for household washing machines and household washer-dryers pursuant to Directive
2009/125/EC of the European Parliament and of the Council, amending Commission Regulation (EC)
No 1275/2008 and repealing Commission regulation (EU) No 1015/2010.
Clauses, notes, tables, figures and annexes which are additional to those in IEC 62512:2012 are
prefixed “Z”.
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
document.
This document has been prepared in view of the upcoming Standardization Request which will be given
to CENELEC by the European Commission and the European Free Trade Association and supports
Commission Delegated Regulation (EU) 2019/2014 and Commission Regulation (EU) 2019/2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
