(Main)Electric dishwashers for household use - Test methods for measuring the performance
Electric dishwashers for household use - Test methods for measuring the performance
Via mandate 481 the European Commission charged Cenelec with the revision of the current test standard to prevent circumvention during energy labelling tests. A dishwasher should not react through the usage of different sensors to a specific test scenario. Due to the fact that a soiled load is used for cleaning performance testing but not for drying performance tests, the test scenarios are not identical. Several solutions were proposed and failed. Finally it was decided to decided to test the applicability of a combined cleaning and drying evaluation (CCD). The method is to be added to the renumbered standard EN60436.

Lave-vaisselle électriques à usage domestique - Méthodes de mesure de l’aptitude à la fonction
La CEI 60436:2004 s'applique aux lave-vaisselle électriques à usage domestique alimentés en eau chaude et/ou froide.
L'objet de la présente norme est d établir et de définir les caractéristiques principales d aptitude à la fonction des lave-vaisselle électriques à usage domestique et de décrire les méthodes normalisées de mesure de ces caractéristiques.
Električni pomivalni stroji za gospodinjstva - Preskusne metode za merjenje lastnosti
Z mandatom 481 je Evropska komisija zadolžila odbor Cenelec, da preveri trenutne preskusne standarde in prepreči, da bi se jim uporabniki med preskusi za energetsko označevanje lahko izognili. Pomivalni stroj naj se z uporabo drugačnih senzorjev ne bi odzval na določen preskusni scenarij. Ker se pri preskušanju pranja uporablja umazano perilo, pri preskušanju sušenja pa ne, preskusna scenarija nista enaka. Predlagane so bile različne rešitve, ki pa niso bile ustrezne. Končno je bilo določeno, da se preskusi ustreznost skupnega ocenjevanja pranja in sušenja (CCD). Metoda se doda na novo oštevilčenemu standardu EN60436.

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".

5.7 Detergent
Replace the text of the paragraph by the following:
For energy labelling and / or ecodesign purposes, the reference detergent B, as described in Annex D,
shall be used.
The quantity shall be as recommended by the manufacturer, but it shall not be more than

dispenser is incorporated in the dishwasher, it shall be used. The dispenser shall be clean and dry prior to
the placement of detergent. In the absence of manufacturer’s recommendations, the detergent shall be
placed in the main compartment of the dispenser.
Detergent from the same batch shall be used for the dishwasher under test and for the reference
dishwasher.
The detergent shall be stored in waterproof bags in quantities of no more than 1 kg in a cool and dry
atmosphere. It shall be used within six months after production and within one month of opening.
Before using, the detergent shall be homogenized in accordance with ISO 607 for example using a

Modify the first paragraph as follows:
The purpose of this test is to measure how well the appliance cleans and dries normally soiled place
settings and serving pieces.
Replace the first sentence of the second paragraph by:
The tests are carried out in parallel with one of the reference machines specified in Annex E or Annex N.

The items should be used for not more than 200 cycles where soiling is applied.
After each cleaning and drying performance test with five to eight cycles a special normalization cycle
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
iodide solution (Merck 109261), which may be obtained from supplier mentioned in Clause F.Z2.
6.3 Soiling agents
Add the following new paragraphs after the last paragraph of 6.3:
All soiling materials used for the reference machine and for the machine under test shall be from the
same batch.
For energy labelling and / or ecodesign purposes, it is necessary that the soilings have the same
properties in all laboratories to ensure comparable and reproducible results.

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