IEC 62512:2012

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.

Lavantes-séchantes électriques à usage domestique - Méthodes de mesure de l'aptitude à la fonction

La CEI 62512:2012 fournit une méthode d'application générale et convenue permettant de soumettre à essai la fonction de lavage et de séchage des lavantes-séchantes. Bien que fondée sur la CEI 61121:2012 relative aux sèche-linge à tambour et sur la CEI 60456:2010 relative aux machines à laver le linge, la présente norme spécifie les conditions qu'il est nécessaire d'appliquer pour soumettre à essai la fonction combinée de lavage et de séchage. La présente norme spécifie les principaux éléments suivants:
- la définition des charges à soumettre à essai au cours de cycles d'opération continus et interrompus;
- la méthode d'essai des opérations automatiques et non automatiques des cycles de séchage;
- le mode de traitement de la charge pour les cycles d'opération interrompus;
- la correction à appliquer aux résultats d'essai des cycles d'opération continus et interrompus.

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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International standard IEC 62512 has been prepared by subcommittee 59D: Home laundry
appliances, of IEC Technical Committee 59: Performance of household and similar electrical

INTRODUCTION
This first edition has been developed to provide 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.
