SC 59A - Electric dishwashers

IEC TS 63331:2024 applies to electric dishwashers for household and similar use that are supplied with hot and/or cold water.
This document deals with measurement procedures regarding the reduction of microbial contamination resulting from the use of electric dishwashers for household and similar use.
This document specifies methods that enable reproducible measurements. These derived measurement results can only be used for a relative statement. Absolute statements, i.e. health-related claims or conclusions about prevention or treatment of a disease or health improvement, are reserved for explicit regulatory action after a medical assessment.
This document does not apply to appliances intended to be used in medical, veterinary, or pharmaceutical applications.
This document does not address sanitization, disinfection or sterilization measures.
The dishwashing process is a complex operation consisting of cleaning dish items and cleaning the dishwasher itself. This document only focusses on the dish items to be cleaned.

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.

IEC 63136:2019 applies to manually loaded under-counter one-tank and one-tank hood-type electrically heated dishwashing machines for washing plates, dishes, glassware, cutlery and similar articles.
These machines are used in commercial kitchens, such as restaurants, canteens, hospitals and in businesses such as bakeries, butchers' shops, etc.
This document does not apply to commercial dishwashers with transport systems (flight-type and rack conveyor dishwashers) and utensil washers.
This document does not apply to undercounter water-change dishwashers.
This document does not apply to appliances designed exclusively for industrial purposes.
The object is to state and define the principal performance characteristics of electric dishwashers for commercial use and to describe the standard methods of measuring these characteristics.
The characteristics are measured by washing plates.
This document is concerned neither with safety nor with minimum performance requirements.
The contents of the corrigendum of March 2021 have been included in this copy.

IEC 60704-2-3:2017 is intended to be used in conjunction with the third edition (2010) of IEC 60704-1, Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 1: General requirements.
The relevant text of Part 1 as amended by this standard establishes the test code for dishwashers.
This edition includes the following significant technical changes with respect to the previous edition:
a) it doesn’t contain the description of an appropriate test enclosure because the test enclosure has been incorporated in IEC 60704-1:2010, Annex B;
b) the values of standard deviations of sound power levels determined according to this part are given in Clause 1;
c) to prevent an appliance being programmed to recognize the test cycles, and reacting specifically to them, in this new edition an artificial soil is used in addition to the unsoiled load and the rinse aid container has to be filled. This artificial soil successive may build up a film on the load. Therefore, detergent also has to be used. An initial test has shown that no foam is to be expected.
This publication is to be read in conjunction with IEC 60704-1:2010.

Applies to single-unit electric dishwashers for household and similar use, with or without automatic programme control, for cold and/or hot water supply, for detachable or permanent connection to water supply or sewage systems, intended for placing on the floor against a wall, for building-in or placing under a counter, a kitchen worktop or under a sink, for wall-mounting or on a counter. Limitations for the use of this test code are given in 1.1.1 of IEC 60704-1.
