Electric dishwashers for household use - Methods for measuring the performance

IEC 60436:2015 applies to electric dishwashers for household and similar use that are supplied with hot and/or cold water. The object is to state and define the principal performance characteristics of electric dishwashers for household and similar use and to describe the standard methods of measuring these characteristics. This standard is concerned neither with safety nor with minimum performance requirements. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:
a) Addition of a specification of the reference dishwasher G1222, addition of the microwave oven 752C, inclusion of standby/low power modes and updated cutlery and tableware items.
b) Combined cleaning and drying: combining the cleaning and drying performance evaluations into one test, along with the energy and water consumption evaluation, prevents an opportunity for circumvention if tests were performed separately. A dishwasher can detect whether soil is present (cleaning evaluation) or not (drying evaluation) and adjust the cycle to favour performance; combining the tests addresses this.
c) New dish load items: new dish load items were incorporated which reflect consumer use. New items are: stainless pots, coffee mugs, melamine plastic items, and glass bowl. The new load items provide different shapes which challenge a dishwasher water spray patterns and provide additional surfaces for soil removal assessment.
d) Detergent: a new detergent "D" is specified which mirrors current tablet formulations available on the market. Detergent type D is phosphate free, with percarbonate instead of perborate bleach and more active enzymes.
e) Repeatability and reproducibility improvements.
f) Addition of annexes for the evaluation of soil sensing programmes, rinsing performance, dishwasher filtration and of an annex on the inlet water temperature influence on energy consumption.

Lave-vaisselle électriques à usage domestique - Méthodes de mesure de l’aptitude à la fonction

L'IEC 60436:2015 s'applique aux lave-vaisselle électriques à usage domestique et similaire 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 similaire et de décrire les méthodes normalisées de mesure de ces caractéristiques. La présente norme ne traite ni des exigences de sécurité ni des exigences minimales relatives à l'aptitude à la fonction. Cette édition constitue une révision technique et inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) Ajout d'une spécification du lave-vaisselle de référence G1222, ajout d'un four à micro-ondes 752C, insertion des modes veille/basse puissance et des couverts et articles de table renouvelés.
b) Nettoyage et séchage combinés: la combinaison des évaluationsd'aptitude au nettoyage et au séchage dans un essai unique, ainsi que l'évaluation relative à la consommation d'eau et d'énergie, empêchent les possibilités de contournement si les essais ont été effectués séparément. Un lave-vaisselle peut détecter la présence (évaluation de nettoyage) ou l'absence (évaluation de séchage) de salissures et ajuster le cycle pour favoriser l'aptitude à la fonction; les essais sont combinés à cette fin.
c) Nouveaux articles de charge: de nouveaux articles de charge ont été incorporés pour refléter l'utilisation du consommateur. Les nouveaux articles sont: marmites en acier inoxydable, tasses à café, articles en mélamine et bols en verre. Les nouveaux articles de charge aux formes différentes défient les systèmes de pulvérisation d'eau du lave-vaisselle et fournissent des surfaces supplémentaires pour l'évaluation d élimination de la salissure.
d) Détergent: un nouveau détergent "D" est spécifié et reflète les formulations des produits actuellement sur le marché. Le détergent de type D ne renferme pas de phosphate, contient un agent de blanchiment au perborate et non au percarbonate et possède un plus grand nombre d'enzymes actives.
e) Améliorations relatives à la répétabilité et à la reproductibilité.
f) Ajout d'annexes pour l'évaluation des programmes de détection de la salissure, de l'aptitude au rinçage et d'une annexe relative à l'influence de la température d'entrée d'eau sur la consommation d'énergie.

• latest date by which this document has to be (dop) 2020-09-27
implemented at national level by publication of an
identical national standard or by endorsement

SIST EN 60436:2020
EN 60436:2020 (E)
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.”
2 Modification of Clause 1 "Scope"
