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.

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.

4 Requirements
The requirements shall be in accordance with Clause 4 of IEC 60456:2010 and Clause 4 of
IEC 61121:2012 as appropriate.
5 Test conditions, materials, equipment and instrumentation
5.1 General
Test conditions, materials, equipment and instrumentation shall be in accordance with
Clause 5 of IEC 60456:2010. However, 5.2.3 of IEC 60456:2010 is modified as indicated in
5.2:
5.2 Ambient temperature and humidity
The ambient conditions shall be in accordance with 5.2.3 of IEC 61121:2012.
6 Preparation for testing
The preparation for testing shall be in accordance with Clause 6 of IEC 60456:2010 and with
6.1 to 6.4 of IEC 61121:2012.
In some cases the normative load for the rated washing capacity includes a lower number of
a specific type of item than the normative load for the rated drying capacity. In this case the
procedure described in Annex A shall be followed. If the test is carried out at the rated
washing capacity, this amount of test load shall be washed and dried. If the rated drying
capacity of the machine under test is lower than the rated washing capacity, the base load
is split after the washing cycle into a first partial load p whose weight is equal to the weight

62512 © IEC:2012 – 9 –
of the rated drying capacity and a second partial load of the remaining items. This causes
an interrupted operation cycle as the test load has to be split between washing and drying
operation. Stain test strips have to be removed at the end of the washing process. The items
used in the first partial load have to be identified in advance of a test series in using their
conditioned weight forming a test load as defined in Table 3 of IEC 61121:2012 at the
required rated drying capacity.
The remaining items shall be dried to a final moisture content of (0 ± 3) % in a tumble dryer
before being reused. Follow Annex A.
If the test is carried out at the rated washing-drying capacity a test load according to
IEC 60456:2010 shall be used and washed and dried in a continuous operation cycle. Stain
test strips are removed at the end of the drying process.
7 Performance measurements – General requirements
The performance measurements shall be in accordance with Clause 7 of IEC 60456:2010.
8 Tests for performance
8.1 Determination of the washing performance
Washing performance shall be measured in accordance with Clause 8 of IEC 60456:2010 with
regard to the cotton test load and 8.3.of this standard.
NOTE The use of other types of textiles is under consideration.
8.2 Determination of the water extraction performance and rinsing performance
The water extraction measurement for interrupted operation cycles shall be done in
accordance with 8.4 of IEC 60456:2010. It does not apply to continuous operation cycles.
The rinsing performance measurement does not apply to this International Standard.
8.3 Determination of the water and energy consumption and programme time
8.3.1 General
This clause specifies the procedure and evaluation for the determination of water and energy
consumption and programme time during washing, spin extraction and drying. It also specifies
the method for the determination of the duration of these cycles and of the complete
operating cycle.
NOTE The tests in this clause may be combined with the tests in 9.1 and 9.2.
8.3.2 Washing cycle
The measurement shall be carried out in accordance with IEC 60456:2010.
8.3.3 Drying cycle
8.3.3.1 General
The mass of the conditioned base load is recorded as W .
A washing cycle shall be performed according to 8.1.

– 10 – 62512 © IEC:2012
The base loads shall be dried to a nominal target final moisture content value of 0 % in
accordance with IEC 61121:2012, Table 6, unless otherwise specified.
The measurements shall be carried out in accordance with 8.2.2 of IEC 61121:2012 and in
conformity with the manufacturer’s instructions.
For washer-dryers with automatic drying (continuous and interrupted) the programme shall
be selected which gives the target final moisture content value. For washer-dryers without
automatic drying (continuous and interrupted) the timer shall be set to obtain the target final
moisture content value given above. The time required for this shall be determined by
monitoring the drying process. This can be done by pre-testing.
8.2.5 of IEC 60456:2010 and 8.2.5 of IEC 61121:2012 using the final moisture content µ as
f
defined in Equation (2) shall be applied accordingly to identify valid test runs. No criterion on
the validity of the average final moisture content of a test series is applied.
There should be no change of setting or control of final humidity (automatic or non-automatic)
for a single test series, except that time controlled drying programmes may be added when
the final moisture content is not achieved.
If at the end of programme the final moisture content is not below the upper limit of the
range of allowable moisture contents a time dependent programme may be added with the
shortest possible time, but not less than 20 min. The additional use of time controlled
programmes shall be reported.
The time this programme takes (including cool-down of this programme) and the energy, and
water used during this time shall be added to the consumption values.
8.3.3.2 Procedure for interrupted operation cycle
Immediately after the washing cycle is finished the strips are removed from the test load and
the test load shall be divided into two parts. The load shall be kept in a plastic bag between
the washing cycle and the drying cycle.
In this case all the items of the base load shall be marked before starting the washing cycle,
in order to identify to which partial load each item belongs. The partial loads shall consist of
the same items throughout the test series.
The initial mass of the first partial load p is recorded as W .

(30 ± 5) min after finishing the washing cycle the load shall be put into the machine, the door
closed and the drying cycle started immediately. The washer-dryer shall be loaded for drying
by shaking every single item before laying them into the drum.
NOTE The described procedure is considered to reflect consumer behaviour.

62512 © IEC:2012 – 11 –
At the end of programme and when the washer-dryer has stopped, the load shall then be
removed within 5 min and immediately weighed. This weight shall be recorded as W .

8.3.3.3 Procedure for continuous operation cycle
At the end of programme and when the washer-dryer has stopped, the load shall be removed
within 5 min, the test strips are separated and the remaining load shall be immediately
weighed. This weight shall be recorded as W .
fp
8.3.4 Determination of energy consumption in "off" mode and "left on" mode
Determination of power consumption in off mode and left on mode shall be made after a
complete operation cycle in accordance with Annex L of IEC 60456:2010.
9 Assessment of performance
9.1 General
After drying the following calculations shall be carried out:
Step 1: Final moisture content:
The final moisture content µ shall be calculated as follows:
f
W −W
f 0
µ = × 100 (2)
f
W
with W either W or W
.
f fc fp
Step 2: Correction of measured values:
– Cold water energy consumption correction shall be made in accordance with 9.5 of
IEC 60456:2010.
– For the interrupted operation cycle, corrections shall be made in accordance with
9.3, 9.4 and 9.5 of IEC 61121:2012 using the actual initial moisture content.
– For the continuous operation cycle, the energy consumption shall be corrected by
the evaporation energy of the water as follows:
µ
f
(3)
E = E + × W × 0,000 628
d m 0c
where 0,000 628 is the evaporation energy of the water (in kWh/g)
.
NOTE The continuous operation cycle has a higher uncertainty in the measured values caused by the
uninterrupted operation cycle. Therefore these values cannot be compared to an interrupted operation cycle.
Step 3: Calculation of following quantities for each valid cycle:
– Drying time
The drying time t is the time for the first partial load to dry including the cool down
dp
period measured during the tests. If the washer-dryer has no cool down period, it shall
be reported.
The drying time does not include the preparation time as specified in 8.3.3.2.
– Total operation time
The total operation time is either the sum of the washing time according to 8.3.2 plus
the drying time for an interrupted operation cycle or it is the time measured for a
continuous operation cycle up to the programme has ended according to 8.3.3.3.
– Energy consumption of the drying cycle

– 12 – 62512 © IEC:2012
The energy consumption of the drying cycle is the energy consumed for drying the
first partial load according to Clause 8.
– Total operation energy consumption
The total operation energy consumption is either the sum of the energy consumption
according to 8.3.2 plus the energy consumption of the drying cycle for an interrupted
operation cycle or the energy consumption measured for a continuous operation
cycle until the programme has ended according to 8.3.3.3.
– Water consumption of the drying cycle
The water consumption of the drying cycle, if any, is the water consumed for drying
the first partial load measured during the tests according to Clause 8 and reported in
litres.
– Total operation water consumption
The total operation water consumption is either the sum of the water consumption
according to 8.3.2 plus the water consumption of the drying cycle for an interrupted
operation cycle or it is the water consumption measured for a continuous operation
cycle until the programme has ended according to 8.3.3.3.
– Averaging the data for drying time (if appropriate), total operation time, energy and
water consumption and final moisture content for all five test cycles.
– Rounding shall only be applied to reported values in Annex B. If numbers have to be
rounded they shall be rounded to the nearest number in accordance with B.3, Rule B
of ISO 80000-1:2009. If the rounding takes place to the right of the comma, the omitted
places shall not be filled with zeros.
NOTE Performance data (time, energy consumption and water consumption) of continuous and non-
continuous drying operation are not comparable.
9.2 Determination of the airborne acoustical noise
Noise emission values, when declared, shall be measured separately for the washing,
spinning and drying cycles in accordance with IEC 60704-2-4 and IEC 60704-2-6. The same
programmes used for the tests under Clause 8 shall be used.
The measurement of airborne acoustical noise shall be done in the interrupted operation
cycle.
10 Data to be reported
Data to be reported shall be in accordance with Clause 11 of IEC 60456:2010 and Clause 10
of IEC 61121:2012, as appropriate, and with Annex B.

62512 © IEC:2012 – 13 –
Annex A
(normative)
Splitting of the base load
When the base load for cotton as defined in IEC 60456:2010 is used, parts of the load have to
be removed for the drying if the rated drying capacity is lower than the rated washing
capacity. In this case it may happen that not enough towels or pillow cases are available to
form a load following the rated drying capacity.
In these cases the splitting of the rated washer load shall be carried out as follows:
1) build a load consisting of the rated number of sheets and pillow cases as declared in
Clause 6 of IEC 60456:2010;
2) add all the towels of the basic load;
3) add pillow cases to reach the minimum rated drying capacity minus 60 g;
4) remove towels until the rated capacity is reached within ± 60 g;
5) in case steps 1 to 4 do not meet the target weight continue with step 6;
6) replace three pillow cases by one more sheet;
7) continue with steps 3 and 4.
For example, the composition of the loads for a rated washing capacity of 9 kg is shown in
Table A.1.
Table A.1 – Composition of loads for rated capacities of 8 and 9 kg
Required test Approximate base Number of sheets Number of Number of
load mass load mass pillowcases towels
kg kg
9 8,82 4 14 23
8 7,84 3 12 25
In this case the number of towels would not be sufficient to form a load complying with a
rated drying capacity of 8 kg, since not enough towels are available in the wash load for the
rated washing capacity of 9 kg.
In this case one of the next heavier items is used, starting with a pillowcase, to form the test
load for the rated drying capacity. In this example this would result in the test load shown in
Table A.2.

LAVANTES-SÉCHANTES ÉLECTRIQUES À USAGE DOMESTIQUE –
MÉTHODES DE MESURE DE L’APTITUDE À LA FONCTION

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a
pour objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les
domaines de l'électricité et de l'électronique. A cet effet, la CEI – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de la CEI"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent
également aux travaux. La CEI collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI ne peut pas être tenue responsable
de l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications
nationales et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications
nationales ou régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de la CEI. La CEI n'est responsable d'aucun des services effectués par les organismes de
certification indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à la CEI, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de la CEI, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de la CEI ou de
toute autre Publication de la CEI, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de la CEI peuvent faire
l’objet de droits de brevet. La CEI ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits
de brevets et de ne pas avoir signalé leur existence.
La Norme internationale CEI 62512 a été établie par le sous-comité 59D: Appareils de lavage
du linge, du comité d’études 59 de la CEI: Aptitude à la fonction des appareils
électrodomestiques et analogues.
Le texte de cette norme est issu des documents suivants:
