Introduction
Replace the existing introductions by the following:
This new edition of EN 50242 / EN 60436 has been developed based on the mandate M/481 to CEN,
CENELEC and ETSI for standardisation in the field of household dishwashers, which relates to
Directive 2009/125/EC of the European Parliament and of the Council and to Directive 2010/30/EU of the
European Parliament and of the Council.
Mandate M/481, issued by the European Commission, includes the standardization task to develop
measures in testing household dishwashers, which ensure “that the prospective harmonised standard(s)
includes a procedure that avoids an appliance being programmed to recognize the test cycles, and
reacting specifically to them, with the exclusion of test cycle recognition that is active only during the
manufacturing of the appliance”.
CLC/TC 59X/WG 2 has identified the deviating test conditions in the previous edition of this standard for
the cleaning performance assessment (soiled test load), including relevant energy and water
consumption measurements, and the drying performance assessment (unsoiled test load), excluding
energy and water consumption measurements, to be the main potential source for an appliance being
programmed to recognize the test cycle, and reacting specifically to them. Therefore, the Combined
Cleaning and Drying evaluation (CCD) has been established to repeal former deviating test conditions,
and to improve alignment with common real life household conditions.
This document submits all common modifications necessary for the application of
IEC 60436:2004/A1:2009 and IEC 60436:2004/A2:2012 in Europe. Accordingly, it incorporates the
changes made in EN 50242:2008/A11:2012 / EN 60436:2008/A11:2012.
In addition, this document submits modifications to Annex O “Additional aspects of the energy
consumption of dishwashers” based on the FDIS draft of IEC 60436 4th Edition prepared by SC 59A
"Electric dishwashers" of IEC/TC 59 "Performance of household and similar electrical appliances".
EN 60436:2016 (E)

shall be used.
The quantity shall be as recommended by the manufacturer, but it shall not be more than
– 2,5 g/place setting for dishwashers with a capacity of ≥ 10 place settings;
– 3,0 g/place setting for dishwashers with a capacity of < 10 place settings.
If no recommendation is given by the manufacturer, use

shall be performed in order to avoid residual scale formation on the test load. For this purpose clean load
is loaded into a dishwasher (no test or reference machine) having a normal / daily use programme. This
programme is run with 30 g of anhydrous fine granular citric acid (Supplier see Clause F.Z2) instead of
detergent for one cycle.
In case new test load is started to use in the tests, ten cycles using detergent (specified in 5.7) and rinse
aid (specified in 5.7) shall be performed in order to avoid the deviations in the test results of tests
performed with new load and used load.
Soup plates (specified in Clause A.2) soiled with oat flakes (specified in 6.4.5) shall be free of starch
residues from the previous tests.
NOTE 3 This can be checked by Lugols solution after each cleaning performance test. Lugols solution is a 1 % Iodine/potassium

7 Drying performance
Replace the heading of Clause 7 by the following:
7 Combined cleaning and drying performance assessment
Replace all subclauses of Clause 7 by the following:
7.1 General
This clause describes the procedure for assessing the cleaning and drying performance.
For each test run the drying assessment of the test machine, including the evaluation of the reference
machine, shall be carried out by one single assessor. The same applies for cleaning performance
assessment. The assessor for drying may or may not be the same person as the assessor for cleaning.
The lighting shall be installed where the evaluation takes place in order to avoid any direct glare. The
luminance measured at the position of evaluation shall be 1 000 lux – 1 500 lux. The colour temperature
shall be between 3 500 K – 4 500 K using diffused light.
The performance assessment is done in the following sequence:
1. Drying evaluation
2. Cleaning evaluation.
After completing each test programme (see 3.4) the dishwasher (reference machine and test unit) shall
be disconnected from the electricity supply; the door or cover is left undisturbed for 30 min.
After 30 min from the completion of the test programme, open the door of the machine completely. Start
the evaluation of the drying performance according to 7.3.
Depending on the equipment of the dishwasher, with or without a separate cutlery rack (not combined
with any other rack), the evaluation of the drying performance has to follow slightly different procedures.
7.2 General requirements to enable subsequent cleaning assessment
It is of general importance to avoid cross-contamination (falling off, transfer or dripping) of soil particles
from one load item to another. In addition, the dishware shall be touched as little as possible (max. at two
positions).
When removing items with cavities (e.g. cups) a horizontal position shall be maintained to avoid spilling
any water residue.
If serving pieces or other parts of the cutlery are positioned in any rack which is not designed exclusively
for cutlery, their drying performance shall be evaluated with the other items of the rack.
A wet rim (no drop or streak) around soil residue shall not be taken into account for the drying
assessment.
If any soil can be found in residual water in cavities (e.g. from bowls or cups), the cleaning performance of
those items shall be evaluated during the drying performance evaluation. In such a case, the cleaning
assessment shall be done by the drying assessor. The soil particles shall be assessed as if they were
dried on. The water and soil in the cup cavities shall not be emptied out into the machine (to avoid carry
over to next cycle run).
When racks have to be removed from the dishwasher, care shall be taken to avoid damaging delicate
parts on the underside such as spray arms. Resting the rack on raised supports may help avoid such
damage occurring. For example, a rack with an attached spray arm shall be placed on a holder.
Close adherence to these timings should guarantee a higher reproducibility and consistency of the drying
performance results.
EN 60436:2016 (E)
7.3 Determination of the drying performance
The evaluation of each item, which consists of removing it from the machine, viewing it, assessing it,
putting it down and recording the score) shall be completed in 8 s ± 1 s. The viewing time for evaluation
shall be 3 s per item.
7.3.1 Drying assessment procedure
Carry out the following evaluation procedures steps:
1 The lower rack shall be pulled out carefully and left on the open door of the dishwasher. The cutlery
basket, if present, shall be removed carefully from the dishwasher.
2 Carry out the drying performance evaluation of the tableware in the lower rack. After assessing each
item, replace it in its original location unless this would restrict access to other items in the rack. In
this case, place such items on a clean, light coloured surface.
3 The lower rack shall be removed from the machine or alternatively the rack shall be covered to avoid
contamination through particles falling from racks on higher levels. Kitchen paper may be used to
cover the baskets.
4 Working upwards through the dishwasher, carry out the drying performance evaluation of the
tableware in each rack following the procedure given for the lower rack in steps 2 and 3.
5 After evaluating the drying performance of the tableware in the uppermost rack, evaluate the drying
performance of the cutlery. After assessing each item of cutlery, either place it separately on a clean
bright surface, or, if a dishwasher has a cutlery rack place each item back in its original position in
the rack. Soil particles which fall from the cutlery during the evaluation shall be retained and included
in the cleaning performance score.
6 When the drying performance evaluation of the whole load has been completed, carry out the
cleaning performance evaluation of the tableware.
The drying evaluation should be carried out near the test machine to avoid drying during transport of
tableware load items in dish racks or cutlery baskets. Dish racks or cutlery baskets removed should be
placed somewhere where no additional heat or air ventilation can influence the drying result.
Inspect each item for possible water residue.
Drying effect is evaluated by visual inspection and judged to be “dry”, “intermediate” or “wet”.
“Dry” is defined as an article being completely free of moisture. In this case, the article shall be given a
score of 2.
“Intermediate” is defined as an article having one or two drops of water, or one wet streak (run). The total
wet area shall be less than 50 mm². In this case, the article shall be given a score of 1.
“Wet” is defined as an article having more than two drops of water, or one drop and one stre
