Electric dishwashers for commercial use - Test methods for measuring the performance

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.

Lave-vaisselle électriques à usage collectif - Méthodes d'essai et de mesure de l'aptitude à la fonction

L'IEC 63136:2019 s'applique aux lave-vaisselle sous comptoir à un réservoir ainsi qu'aux lave-vaisselle à capot à un réservoir, à chauffage électrique et à charge manuelle, destinés à laver les assiettes, plats, verres, couverts et articles analogues. Ces machines sont utilisées dans les cuisines collectives, notamment les restaurants, les cantines, les hôpitaux, et dans les entreprises telles que les boulangeries, boucheries, etc. Le présent document ne s'applique pas aux lave-vaisselle à usage collectif comportant des systèmes de transport (lave-vaisselle à convoyeur et à avancement automatique des paniers), ni aux lave-ustensiles. Le présent document ne s'applique pas aux lave-vaisselle sous comptoir à changement d'eau. Le présent document ne s'applique pas aux appareils conçus exclusivement pour des usages industriels. L'objet du présent document est d'établir et de définir les caractéristiques principales d'aptitude à la fonction des lave-vaisselle électriques à usage collectif et de décrire les méthodes de mesure normalisées de ces caractéristiques. Les caractéristiques sont évaluées par le lavage d'assiettes. Le présent document ne traite ni de la sécurité, ni des exigences minimales d'aptitude à la fonction.

Električni pomivalni stroji za komercialno uporabo - Preskusne metode za merjenje lastnosti

Ta tehnični standard se uporablja za podpultne pomivalne stroje za ročno nalaganje z enim rezervoarjem in pomivalne stroje z enim rezervoarjem, pokrovom ter električnim ogrevanjem za pomivanje krožnikov, posode, steklene posode, jedilnega pribora in podobnih izdelkov. Ti stroji se uporabljajo v komercialnih kuhinjah, na primer v restavracijah, menzah, bolnišnicah, ter v obrtnih enotah, kot so pekarne, mesnice itd. Ta dokument se ne uporablja za komercialne pomivalne stroje s tračnimi sistemi (tračni in komorni pomivalni stroji) ter pomivalne stroje za jedilni pribor. Ta dokument se ne uporablja za podpultne pomivalne stroje z menjavo vode. Ta dokument se ne uporablja za naprave, zasnovane izključno za industrijsko uporabo. Namen tega standarda je navesti in opredeliti glavne značilnosti delovanja električnih pomivalnih strojev za komercialno uporabo ter opisati standardne metode merjenja teh značilnosti. Značilnosti se merijo na podlagi pomivanja krožnikov. Ta dokument ne opredeljuje varnostnih zahtev niti minimalnih zahtev glede zmogljivosti.

ELECTRIC DISHWASHER FOR COMMERCIAL USE –
TEST METHODS FOR MEASURING THE PERFORMANCE
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC

Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 63136 has been prepared by subcommittee 59A: Electric

dishwashers, of IEC technical committee 59: Performance of household and similar electrical

appliances.
EN 50593:2017 has served as a basis for the elaboration of this standard.

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.
