HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES – TEST CODE
FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE –

Part 2-3: Particular requirements for dishwashers

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 60704-2-3 has been prepared by subcommittee 59A: Electric
dishwashers, of IEC technical committee 59: Performance of household and similar electrical
appliances.
This fourth edition cancels and replaces the third edition published in 2017. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Alignment to IEC 60704-1:2021
b) Change of the position of the test sample in the test enclosure (aligned to IEC60704-1:2021)
c) Detergent changed (aligned to IEC 60436)
The text of this standard is based on the following documents:

FDIS Report on voting
xxx xxx
Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 2-3 is intended to be used in conjunction with the fourth edition of
IEC 60704-1:2021, Household and similar electrical appliances – Test code for the
determination of airborne acoustical noise – Part 1: General requirements.
The relevant text of IEC 60704-1:2021 as amended by this standard establishes the test code
for dishwashers.
This Part 2-3 supplements or modifies the corresponding clauses in IEC 60704-1:2021, so as
to establish the test code for dishwashers. When a particular subclause of IEC 60704-1:2021
is not mentioned in this Part 2-3, that subclause is applicable as far as reasonable. Where this
standard states "addition", "modification" or "replacement", the relevant requirements, test
specifications or explanatory matter in IEC 60704-1:2021 should be adapted accordingly.
Subclauses, tables and figures that are numbered starting from 101 are additional to those in
IEC 60704-1:2021.
Unless notes are in a new subclause or involve notes in IEC 60704-1:2021, they are numbered
starting from 101, including those in a replaced clause or subclause.
Additional annexes are lettered AA, BB, etc.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

1 INTRODUCTION
2 The measuring conditions specified in this Part 2-3 provide for sufficient accuracy in
3 determining the noise emitted and comparing the results of measurements taken by different
4 laboratories, whilst simulating as far as possible the practical use of dishwashers.
5 It is recommended to consider the determination of noise levels as part of a comprehensive
6 testing procedure covering many aspects of properties and performance of household
7 dishwashers.
8 NOTE As stated in the Introduction to IEC 60704-1:2021, this test code concerns airborne noise only.

13 Part 2-3: Particular requirements for dishwashers
17 1 Scope
18 Addition:
19 These particular requirements apply to single unit electric dishwashers for household and
20 similar use, with or without automatic programme control, for cold and/or warm water supply,
21 for detachable or permanent connection to water supply or sewage systems, intended for
22 placing on the floor against a wall, for building-in or placing under a counter, a kitchen worktop
23 or under a sink, for wall-mounting or on a counter.
24 2 Normative references

26 IEC 60436:20xx, Electric dishwashers for household use – Methods for measuring the
27 performance
Note from Secretary of SC59A: IEC 60436 is under revision and is foreseen to be
published by the end of 2024. This document will reference the latest version of
IEC 60436.
29 3 Terms and definitions

31 operational cycle
32 Replacement:
33 starts with the initiation of the programme (excluding any user programmed delay) and ends
34 when all activity ceases (i.e. the dishwasher may revert to off mode or it may have a steady
35 state power consumption until the user opens the dishwasher or turns the unit off )
36 Note 1 to entry: Audible program end signals should be switched off or set to the lowest configuration. If this is not
37 possible the audible signals shall be included in the measurement.
38 3.101

50 4.2 Direct method
51 Addition:
52 If pure tone components are present in the noise emitted by the source, the estimated standard
53 deviation of the measured sound pressure levels in the special reverberation room can increase.
54 In such cases, additional microphone positions or source positions can be necessary, as
55 specified in ISO 3743-2:2018.
