Endorsement notice
The text of the International Standard IEC 60436:2015 was approved by CENELEC as a European Standard
with agreed common modifications.

1 Modification of Introduction
Replace by:
“This edition of the standard EN 60436 Electric dishwashers for household use - Methods for measuring
the performance was developed for the future EU energy labelling and ecodesign scheme and
therefore based on the principle described in the mandate M/481 to CEN, CENELEC and ETSI for
standardisation in the field of household dishwashers relating to REGULATION (EU) 2017/1369 OF
THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 4 July 2017 setting a framework for energy
labelling and repealing Directive 2010/30/EU.

Mandate M/481, issued by the European Commission, includes the standardisation task to develop
measures in testing household dishwashers, which ensure that the prospective harmonized standard
takes into account improved test conditions and test materials to better reflect the user behaviour and
the state of the art at European and international level. Test conditions described in IEC 60436:2015
indeed represent today’s usage behaviours of European households in a better manner.

Common modifications were developed to further improve the standard for its application concerning
EU energy labelling and ecodesign purposes, specifically in regard to the measurement procedure for
low power modes, uncertainty of measurements, and test burden.”

is air-tight and kept in the dark. Once the container has been opened, the remaining dry matter spinach
may be used for four weeks provided it is stored in a re-sealed container in the dark.
For reconstitution of the quantities of minced spinach needed, an appropriate amount of this dry matter
spinach is taken and distilled water is added. Follow the supplier’s (e.g. Annex L.1.11) instruction when
reconstituting the spinach for a test. After reconstituting the spinach shall be handled and stored like
the de-frosted and ground spinach.
Freeze dried spinach from listed suppliers (refer to Annex L) has been proven to result in equivalent

Add the following paragraph after the last paragraph:

“For energy labelling and ecodesign purposes, this subclause is not applicable.”
6.6 Loading and operating
6.6.2 Operating
Modify the first paragraph as follows:

“During the performance tests the starting of the machines may have to be staggered to ensure there is enough
time for a single assessor to assess the performance of each machine at the prescribed time after its cycle
programme finishes. However, test machines shall run at the same time as part of the reference machine
cycle programme.”
Replace the second sentence of the fifth paragraph by the following:

“The index for cleaning is calculated at the number of test runs in the test series in which the value of
ln W C is satisfied. The index for drying is calculated at the number of test runs in the test series in
which the value of ln W is satisfied. These respective numbers of test runs in the test series may be
D
different.”

unglazed edges of porcelain, pot handles or caught between handle and pot body.”
7.2.2 Drying assessment procedure

Replace the first paragraph by the following:

“After completing each test programme the reference machine and test machine shall be
disconnected from the electricity supply; the door or cover is left undisturbed for 30 min. At the end of
this period, open the door of the machine completely and start the assessment of drying performance
immediately.
When a manufacturer provides information (together with the information asked for under 5.1.1) that
at end of programme all activity ceases, the test machine can remain connected to the supply. It shall
be noted in the test report whether the test machine was disconnected or remained connected to the
main supply.”
Replace the Table 1 by the following:

Score Amount of water residue
2 The item is completely free from water residue.
The item has up to two drops of water, or one wet streak (run), or a total wet area of up to 50
mm .
The item has more than two drops of water, or one drop and one streak, or two streaks, or a
total wet area of more than 50 mm .

Replace the text of the last paragraph by the following:
“Record four scores for each pot excluding pot handles:

“There may be significant variations in the water consumption, energy consumption, cycle time or
programme time measured for some of the test runs in a test series.”

Delete the last sentence of the third paragraph.

Add the following text after the third paragraph:

“When calculating the arithmetical mean value of the energy, water consumption and programme time
for dishwashers, where the regeneration of the water softener depends on demand and water
hardness, and does not take place on every cycle, test runs where regeneration took place within
the test series shall be disregarded when increased water, energy consumption and programme time
are in line with manufacturer’s instructions to the consumer in regard to the following points:
- The total impact on the quantity of water, and electrical energy and the period of time
associated with one complete regeneration;
- the frequency with which the softener is regenerated;
- the moment(s) in time during the programme that the regeneration takes place.
The regeneration process may consist of several stages. It may start during one test run and finish
during the following test run. For this purpose, when the regeneration event is in line with
manufacturer’s instructions to the consumer, test runs during which a regeneration operation took
place within the test series shall be disregarded for the purposes of calculating the mean
consumption values. However, no more than two test runs in a test series of five runs, and no more
than three test runs in a test series of six to eight runs shall be disregarded.
NOTE Z1  The information expected to be provided would include regeneration information regarding the water
used for testing according to this standard.
NOTE Z2  The measured energy, water, and time of regeneration operations may vary. If these values differ by
more than 10% from the consumption values provided by the manufacturer, then the laboratory should seek
further guidance from the manufacturer.

If the information provided by the manufacturer is not in line with the measurement or in the absence
of consumer information regarding the impact of regeneration operations on water, energy, and time,
data from all test runs shall be used for the calculation of the mean value for the test series.
In the test report, the test runs in which regeneration of the water softener occurred shall be identified.”
8.2.2 Energy consumption
Modify as follows:
“The energy consumption for the whole test run is calculated from the measured electrical energy
consumption E and the energy of the supplied hot water E (if any), and stated for each test run in
e h
the test report.
The mean energy consumption shall be calculated from the energy consumption for every whole test
run except those test runs where a regeneration event has been identified in accordance with the
manufacturer’s instructions to the consumer as described in 8.2.1.
