Overview
IEC 60436:2025 is the fifth edition of the International Standard by the International Electrotechnical Commission (IEC) addressing performance measurement methods for electric dishwashers for household use. This standard applies to dishwashers supplied with hot and/or cold water, including free-standing, built-in, integrated, and multi-compartment models. The document defines principal performance characteristics and elaborates on standardized test methods to assess these key features. Importantly, the standard focuses solely on performance measurement and does not cover safety or minimum performance requirements.
Updated in 2025, IEC 60436 replaces the 2015 edition and the 2020 amendment, introducing a range of technical revisions aimed at reflecting modern dishwasher technologies and market formulations.
Key Topics
Reference Machine and Detergent: Introduction of a new reference machine better suited to evaluate energy and water-saving innovations in modern dishwashers. The standard also updates to a new reference detergent type E that includes upgraded enzymes and a lower silicate content to reduce alkalinity, easing global transportation and usage.
Cleaning Performance Alignment: A scientific alignment factor has been implemented to correlate previous cleaning performance test results with those obtained using the updated reference system.
Component Replacements: New replacements for key soiling components like pans and knives have been introduced due to discontinuation of previous models.
Temperature Control Enhancements: Room temperature measurement is now conducted inside the dishwasher just prior to test start for improved accuracy.
Load Weight Updates: The weight of load items has been revised and specified ranges adjusted to better reflect actual tableware weights.
Low Power Mode Testing: An updated, stepwise method for evaluating low power consumption modes, including network standby, has been developed. This addresses the energy profile of dishwashers with internet-connected smart features.
Unit Variation Assessment: A new approach allows testing of multiple dishwasher units from the same model to better understand performance variations.
Loading and Handling Instructions: New requirements provide clearer guidance for test institutes to standardize loading and handling during testing.
Multi-Compartment Dishwashers: Specific testing methodologies for dishwashers with multiple compartments have been incorporated.
Soil Preparation Process: Improvements to the ballast soil preparation process ensure consistent soiling used in cleaning tests.

Electric dishwashers for household use - 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) IEC draws attention to the possibility that the implementation of this document may involve
the use of (a) patent(s). IEC takes no position concerning the evidence, validity or applicability
of any claimed patent rights in respect thereof. As of the date of publication of this document,
IEC had not received notice of (a) patent(s), which may be required to implement this document.
However, implementers are cautioned that this may not represent the latest information, which
may be obtained from the patent database available at https://patents.iec.ch. IEC shall not be
held responsible for identifying any or all such patent rights.
IEC 60436 has been prepared by subcommittee 59A: Electric dishwashers, of IEC technical
committee 59: Performance of household and similar electrical appliances. It is an International
Standard.
This fifth edition cancels and replaces the fourth edition published in 2015, and Amendment
1:2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Implementation of a new reference machine, which better reflects modern dishwasher
energy and wate
