Overview

EN IEC 63136:2019 (adopted by CLC/CENELEC) is the international test-method standard for electric dishwashers for commercial use. It applies to manually loaded, under-counter one‑tank and one‑tank hood‑type electrically heated dishwashing machines used for plates, dishes, glassware, cutlery and similar articles in commercial kitchens (restaurants, canteens, hospitals, bakeries, butchers, etc.). The standard defines how to measure principal performance characteristics by washing plates; it is explicitly not a safety standard and does not set minimum performance requirements. Exclusions include flight‑type and rack conveyor dishwashers, utensil washers, under‑counter water‑change dishwashers and appliances intended solely for industrial use.

Key Topics

• Scope and definitions for commercial under‑counter electric dishwashers (IEC 63136:2019 / EN IEC 63136:2019).
• General measurement conditions: conditioning of the machine, electricity supply, ambient conditions, water supply (temperature, hardness, pressure), detergents and rinse aids, load configuration and temperature probe positioning.
• Cleaning and resoiling performance: standardized soil preparation and application, dot‑pattern test plates, evaluation procedures and calculation of cleaning performance.
• Energy, water consumption and cycle time: standardized methods for measuring initial fill, start‑up, programme energy use, water consumption and ready‑to‑use power.
• Data reporting and evaluation: required laboratory/test data, measurement records and example evaluation sheets.
• Annexes with test materials and fixtures (reference detergent and rinse aid, basic cleaning detergent, stainless steel supports, pipette/dispenser, sesame seeds for tests).

Applications

EN IEC 63136:2019 is used by:

• Manufacturers and R&D teams to validate and compare washer designs and cleaning performance.
• Independent test laboratories to produce reproducible, documented performance reports.
• Procurement specialists and large food service operators specifying equipment based on measured water, energy and cleaning metrics.
• Certification bodies and consultants assessing performance claims and supporting eco‑efficiency labeling or tender evaluations.
• Product managers and marketers preparing objective performance data for product sheets and competitive benchmarking.

Practical outcomes include repeatable cleaning-performance data, comparable energy and water consumption figures, and a common test language for commercial dishwasher performance claims.

Related Standards

• Supersedes: EN 50593:2017 (and its amendments)
• Referenced/harmonized standards (not replaced): IEC 60335‑1, IEC 60335‑2‑58, IEC 60734, IEC 62053‑21 (noting harmonized European versions where applicable).

Using EN IEC 63136:2019 ensures consistent, transparent measurement of commercial dishwasher performance for product development, procurement and lab testing.

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.
