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.
The text of this International Standard is based on the following documents:

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


1 Scope
This document 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.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition
cited applies. For undated references, the latest edition of the referenced document (including
any amendments) applies.

boiler, heating, operation of pumps and fans.
3.5
programme time
time that is measured from the initiation of the programme (excluding any user-programmed
delay) until an end of programme indicator is showing the end of the programme
Note 1 to entry: If there is no end of programme indicator, the programme time is equal to the cycle time.

3.10
energy-consuming element
electrical consumer (e.g. heaters, fans, pumps) in the dishwasher
Note 1 to entry: The control system is not considered as an energy-consuming element.
3.11
washware
materials and utensils that come into contact with foodstuffs and re-usable crates/containers
that are cleaned in a commercial dishwasher
