European foreword
This document (EN 60456:2016) consists of the text of IEC 60456:2010 prepared by SC 59D
“Home laundry appliances” of IEC/TC 59 "Performance of household and similar electrical ap-
pliances”, together with the common modifications prepared by CLC/TC 59X "Performance of
household and similar electrical appliances".

The following dates are fixed:

(dop) 2016-12-14
• latest date by which this document has to be imple-
mented at national level by publication of an identical
national standard or by endorsement
• latest date by which the national standards conflicting (dow) 2018-12-14
with this document have to be withdrawn

This document supersedes EN 60456:2011.
Significant technical differences are:
a) the test procedure to measure power and energy consumption in left-on-mode and the
referenced standard has been corrected; (Z.A. 4.9);
b) deletion of RMS and two sided confidence level formulas (Z.A. 5.2);
c) corrections in evaluation of water extraction performance (formulas) are integrated (Z.A.
5.4);
d) corrections in evaluation of spin speed (formulas) are integrated (Z.A. 5.5);
e) corrections in evaluation of power and energy consumption measurements in left-on-
mode (formulas and references) are integrated (Z.A. 5.9);
f) Table ZA17: Correction of the reported precision;
g) Annex ZB is re-phrased;
h) the normative references in Annex ZC are updated;
i) new Annexes ZZA and ZZB.
This European Standard also specifies, as far as necessary, the test methods which shall be
applied in accordance with the COMMISSION DELEGATED REGULATION (EU) No
1061/2010 implementing Directive 2010/30/EU of the European Parliament and of the Council
with regard to energy labelling of household washing machines and in accordance with the
COMMISSION REGULATION (EU) No 1015/2010 implementing Directive 2009/125/EC of the
European Parliament and of the Council with regard to ecodesign requirements for household
washing machines.
Clauses, subclauses, notes, tables, figures and annexes which are additional to those in
IEC 60456:2010 are prefixed “Z”.
Annex ZA sets out the procedure to be applied for testing according to Commission Regula-
tions with regard to energy labelling and ecodesign and provides all necessary links to all rel-
evant clauses of this European Standard.
Annex ZB has been re-phrased and provides control procedures for checking measured val-
ues in comparison to values declared by the manufacturer and taking into account any permit-
ted tolerances.

5 Test conditions, materials, equipment and instrumentation
5.1 General
Add
Rounding rules that are given in the regulation supersede standardization.
5.2 Ambient conditions
5.2.1 Electricity supply
Replace the text under 5.2.1 as follows:
The supply voltage to each test washing machine 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 Z1  In the case of a fixed cable, the plug (or the end of the cable) is the reference point at which the supply
voltage shall be maintained.

The supply frequency to each test washing machine shall be maintained at 50 Hz ± 1 %
throughout the test.

5.2.2 Water supply
5.2.2.2 Water hardness
Add after the first paragraph the following new paragraph:
For the combined test series according to Annex ZA water with a total hardness of
(2,5 ± 0,2) mmol/l (hard water) shall be used.
5.2.2.3 Water temperature
Add after NOTE 1 the following new paragraph:
For the combined test series according to Annex ZA the temperature of the hot water supply
(if applicable) shall be set according to declaration given by the manufacturer (± 2 K) in the
instruction manual. If no clear indication is given, the hot water supply temperature shall be
set at (60 ± 2) °C.
When the manufacturer specifies a hot water temperature range, which includes (60 ± 2) °C,
the hot water temperature shall be set at (60 ± 2) °C. When the manufacturer specifies a hot
water temperature range, which does not include (60 ± 2) °C, the hot water temperature shall
be set at the end of the temperature range which is closest to (60 ± 2) °C. When the manufac-
turer specifies a single temperature with a tolerance, then that temperature shall be used.
The hot and cold water inlet supply temperature (as applicable) shall be determined as close
as possible to the point of connection of each test washing machine to the laboratory water
supply system.
Add at the end the following new paragraph and replace NOTE 2 as follows:
For the combined test series according to Annex ZA the water supply system shall be config-
ured so that the temperature of all water entering the inlet hose of the test washing machine
is within specified tolerance with the exception of up to 250 ml of each increment. A tempera-
ture recording system shall record inlet water temperature at intervals of no less than once
per second.
NOTE 2 Clause 8 requires water temperatures and volumes to be recorded on a continuous basis during filling in
order to determine weighted average temperature.

6 Preparation for testing
6.2 Test washing machine and reference machine preparation

6.2.1.3 Preparation of the test washing machine for a test series

Replace the second paragraph by:
Any filters shall be thoroughly cleaned before each test series. Prior to the test series (not
less than one day in advance but not more than two week in advance and without any other
run before the test series is started) a cleaning run shall be undertaken on a programme
with the maximum wash temperature set and setting maximum main wash water level if appli-
cable without load and without detergent. After the cleaning run the machine shall stay stand-
ing at the stable laboratory ambient temperature until the test series is finished.

6.2.1.4 Preparation of the test machine for a test run

Replace the second paragraph by:
The test washing machine shall be at laboratory ambient temperature at the beginning of
each test run. 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 open and standing at the stable laborato-
