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

Part 2-16: Particular requirements for washer-dryers

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 60704-2-16 has been prepared by subcommittee 59D: Home and
similar laundry appliances of IEC technical committee 59: Performance of household and
similar electrical appliances.
The text of this International Standard is based on the following documents:

INTRODUCTION
The noise of washer-dryers has been measured up to now by making use of two standards,
IEC 60704-2-4 and IEC 60704-2-6. This first edition of IEC 60704-2-16 makes it possible to
test the noise of washer-dryers by using one single standard. The following significant
technical changes with respect to the separate use of IEC 60704-2-4:2011 and
IEC 60704-2-6:2012 have been introduced:
• measurement uncertainty and standard deviations are taken into account,
• definition of periods and cycles, in particular definition of thermal spin period and
continuous cycle,
• definitions of standard test programme and standard test load,
• location and mounting,
• information to be reported.
The measuring conditions specified in this document provide for sufficient accuracy in
determining the noise emitted and comparing the results of measurements taken by different
laboratories, whilst simulating as far as possible the practical use of household washer-
dryers.
It is recommended to consider the determination of noise levels as part of a comprehensive
testing procedure covering many aspects of the properties and performance of household
washer-dryers.
NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.

1.1.3 Size of the source
Replacement:
The method specified in ISO 3744 is applicable to noise sources of any size. When applying
ISO 3743-1 and ISO 3743-2, care should be taken that the maximum size of the washer-
dryers under test fulfils the requirements specified in 1.2 of ISO 3743-1:2010 and 1.3 of
