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 60704-2-20 has been prepared by subcommittee 59F: Surface cleaning appliances, of IEC
technical committee 59: Performance of household and similar electrical appliances. It is an
International Standard.
The text of this International Standard is based on the following documents:

The relevant text of IEC 60704‑1:2021 as amended by this document establishes the test code
for wet hard floor cleaners.
This document supplements or modifies the corresponding clauses in IEC 60704-1:2021. When
a particular subclause of IEC 60704-1:2021 is not mentioned in this document, 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 additional to those in Part 1 are numbered starting from
101. Additional annexes are lettered AA, BB, etc.
Unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from
101, including those in a replaced clause or subclause.
In this standard, the following print types are used:
– terms defined in Clause 3: bold type.
A list of all parts in the IEC 60704 series, published under the general title Household and
similar electrical appliances - Test code for the determination of airborne acoustical noise, can
be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
– reconfirmed,
– withdrawn, or
– revised.

INTRODUCTION
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 wet hard floor cleaners.
It is recommended to consider the determination of noise levels as part of a comprehensive
testing procedure covering many aspects of properties and performance of household wet hard
floor cleaners.
NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.

1 Scope
Addition:
This document specifies the determination of airborne acoustical noise of mains operated and
cordless wet hard floor cleaning appliances for household or similar use. In the case of
appliances with combined functionality, this document only addresses the wet cleaning
functionality.
This document does not apply to wet hard floor cleaning appliances for industrial or professional
purposes and robotic wet hard floor cleaning appliances.
NOTE 101 This document is not intended for cleaning appliances according to IEC 60335-2-79, IEC 60704-2-1,
IEC 60704-2-17.
This document describes the determination of the noise emission of wet hard floor cleaners
under normal operating conditions on hard floor in accordance with 4.6 of
IEC/ASTM 62885-6:2023.
NOTE 102 For determining and verifying noise emission values declared in product specifications, see
