European foreword

This document (EN 60456:2016/A11:2020) consists of the text IEC 60456:2010 prepared by SC
59D "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 (dop) 2021-07-21
be implemented at national level by publi-
cation 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withdrawn
Significant technical differences are:
a) the programme to be tested for the combined test series is the new introduced eco 40-60
programme. This programme needs to be tested with default settings with the given temper-
ature;
b) the test loads that have to be used for testing are full, half and quarter of the rated capacity
of the washing machine. Therefore, a new quarter load is introduced and defined to be ap-
proximately a quarter of the rated capacity (see table ZA15). The quarter load is treated as a
separate load and not created by dividing full load or half load;
c) the number of test runs per treatment for the combined test series changed to 3 tests with
full load, 4 tests with half load and 3 tests with quarter load;
d) the time between two subsequent test runs within one day changed from 2 h to one hour;
e) the normalization run is included in the calculation of the load age. The maximum number of
usages for the cotton base load per item is changed to 96 and the weighted average age of the
base load is changed to be between 35 and 60 normalisation runs and test runs.
f) rinsing effectiveness is integrated. It is referred to CLC/TS 50677 (see ZA 4.10);
g) temperature inside the load is integrated. It is referred to CLC/TS 50707:2020 (under prepa-
ration) (see ZA4.11);
h) the procedure to measure low power modes is modified (see ZA4.9);
i) specific weighting factors are introduced for the calculation of the weighted average value of
the combined test series and
j) Annex ZB Tolerances and control procedures is deleted. Annex ZB is replaced by an new
Annex ZB which defines the testing procedure for multi-drum washing machines.
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 Di-
rective 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 Commis-
sion regulation EU) No 1015/2010.

performance for one treatment.
3.1.22
rated capacity
maximum mass of dry textiles of a particular type which the manufacturer declares can be treated in the
test washing machine on the programme selected; for multi-drum mode washing machines the
rated capacities are for each individual drum
Note Z1 to entry: For different textile types the rated capacity of a multi-drum washing machine is usually different.
3.1.23
programme time
the time from the initiation of the programme (excluding any user programmed delay) until the
end of the programme and if the end of programme is not indicated, the programme time is
equal to the cycle time
3.1.24
end of programme
the time when the test washing machine indicates the end of the programme and the load is
accessible to the user; where there is no end of programme indicator and the door is locked
during operation, the programme is complete when the load is accessible to the user; where
there is no end of programme indicator and the door is not locked during operation, the pro-
gramme is complete when the power consumption of the appliance drops to some steady state
condition and is not performing any function
Note to entry Z1: An indication of the end of the programme may be in the form of a light (on or off), a sound, an
indicator shown on a display or the release of a door or latch. In some washing machines there may be a short
delay from an end of programme indicator until the load is accessible by the user.

3.1.Z13
multi-drum washing machine
washing machine equipped with more than one drum whether in separate units or in the same
casing
3.1.Z14
multi-drum mode
programme where some or all of the drums of a multi-drum washing machine are operated
simultaneously
Note Z1 to entry: A washing machine with more than one drum for the treatment of the textiles, where drums cannot
be operated simultaneously is not regarded as having a multi-drum mode. In this case each drum has to be tested
separately.
Note Z1 to entry: This definition may apply only for specific programmes. In this case only these programmes can
be tested in multi-drum mode.
Add the following:
3.1.Z15
simultaneous programme
series of operations which are pre-defined within the multi-drum washing machine and which
are declared by the manufacturer as suitable for washing certain textile types in two or more
drums at the same time
3.1.Z16
simultaneous cycle
complete washing process, started at the same time for two or more drums, as defined by the
simultaneous programme selected, consisting of a series of operations (wash, rinse, spin,
etc.) and including any operations that occur after the completion of the simultaneous pro-
gramme
Note Z1 to entry: Examples of operations that may occur after the completion of the programme are pumping,
monitoring and anti-creasing (where applicable).
3.1.Z17
combined rated capacity
sum of rated capacities of all drums suitable for running a simultaneous programme
3.1.Z18
combined programme time
the time from the simultaneous initiation of the programme for two or more drums (excluding
any user programmed delay) until the end of the simultaneous programme; if the end of
programme is not indicated, the combined programme time is equal to the combined cycle
time
3.1.Z19
combined cycle time
time from the simultaneous initiation of the programme for two or more drums (excluding any
user programmed delay) until all activity ceases; activity is considered to have ceased when
the power consumption reverts to a steady state condition that persists indefinitely without user
intervention; if there is no activity after the end of the programme, the combined cycle time
is equal to the combined programme time
Note Z1 to entry: Cycle time includes any activity that may occur after the programme is completed. This could
include any electronic activity or any additional mechanical activity that occurs for a limited period after any end of
programme indicator. Any cyclic event that occurs indefinitely is considered to be steady state.

3 Modification to Clause 5, "Test conditions, materials, equipment and
instrumentation"
5.1 General
Delete the following sentence:
Rounding rules that are given in the regulation supersede standardization.
5.2 Ambient conditions
5.2.2 Water supply
5.2.2.3 Water temperature
Replace Note 2 by the following note:
NOTE Z Clause ZA.4.8 describes the recording of water volumes on a continuous basis during filling in order to
determine weighted average temperature.
5.3.2 Base loads
5.3.2.1 Cotton base load
Add after the first paragraph the following note:
NOTE Z1 For the combined test series according to Annex ZA one base load is used to test the full load and half
load and a separate base load is used to test the quarter load.
5.5 Instrumentation and accuracy

4 Modification to Clause 6, "Preparation for testing"
6.2 Test washing machine and reference machine preparation
6.2.1 Test washing machine
6.2.1.3 Preparation of the test washing machine for a test series
Replace the 2nd paragraph with the following:
All filters shall be thoroughly cleaned before each combined test series.
After cleaning the filters a cleaning run shall be undertaken on a programme with the maximum
wash temperature set and setting maximum main wash water level if applicable, without load
and without detergent.
The cleaning run shall be carried out not less than one day in advance but not more than two
weeks in advance and without any other run before the combined test series is started.
After the cleaning run the test washing machine shall be allowed to cool down to the ambient
temperature of the test room. It shall be accepted that this requirement has been met if the
internal surface temperature of the test washing machine drum is at ambient air temperature
of the test room, or if the test washing machine has been left standing at stable laboratory
ambient temperature with the door left o
