Overview

EN IEC 60704-2-20:2026 is a European and international standard developed by CLC and IEC that specifies the procedures for determining the airborne acoustical noise emitted by household and similar wet hard floor cleaning appliances. It applies to both mains-operated and cordless wet hard floor cleaners but excludes industrial, professional, and robotic appliances, as well as those covered by other specific IEC standards such as IEC 60335-2-79, IEC 60704-2-1, and IEC 60704-2-17.

The standard outlines the requirements and methodologies for measuring noise emission under normal operating conditions, using a standardized hard floor surface. The results are intended to support manufacturers, laboratories, and regulatory bodies in declaring and verifying the sound power levels of wet hard floor cleaners, thus enabling more accurate and comparable product information.

Key Topics

• Scope and Applicability

  • Applies to household and similar use wet hard floor cleaners (including cordless models)
  • Focuses solely on wet cleaning functionality where combined appliances are concerned
  • Excludes devices designed for industrial, professional, or robotic use

• Measurement Methods

  • Details both direct and comparison methods for noise measurement, outlining procedures for handling acoustical environments
  • Specifies the use of ISO 3743-1, ISO 3743-2, and ISO 3744 measurement methods for the acoustical environment
  • Describes requirements for the stabilization and pre-conditioning of appliances prior to testing

• Instrumentation

  • Guidance on microphones and the use of windscreens
  • Procedures for correcting sound pressure levels based on microphone sensitivity changes

• Test Set-Up

  • Standardization of equipment handling (positioning of handles, use of cleaning heads, and appliance settings)
  • Pre-conditioning steps for both steam cleaners and other wet hard floor cleaners, such as pad preparation and running-in requirements
  • Operating appliances on a standardized hard floor with specified properties to ensure uniformity

• Data Reporting

  • Outlines the necessary information to be recorded and reported for each test, including cleaning head type, settings, and type of hard floor used

Applications

EN IEC 60704-2-20:2026 is essential for:

• Manufacturers: Enables the provision of standardized and comparable airborne acoustical noise data in product documentation, supporting transparency and regulatory compliance.
• Testing Laboratories: Offers validated and reproducible procedures for sound power level determination, ensuring laboratory-to-laboratory consistency.
• Regulatory Agencies: Guides market surveillance authorities in verifying noise emission claims made in accordance with product specifications.
• Consumers: Provides reliable noise level information, assisting in the selection of quieter and more efficient wet hard floor cleaning appliances.

This standard is also valuable in the context of eco-labeling, energy labeling, and product safety certification, where accurate noise measurement is an important parameter.

Related Standards

When using EN IEC 60704-2-20:2026, consider referencing the following related standards:

• IEC 60704-1:2021: General requirements for airborne acoustical noise test codes for household and similar appliances.
• IEC/ASTM 62885-6:2023: Methods for measuring the performance of wet hard floor cleaning appliances.
• IEC 60704-3: Procedures for determining and verifying declared noise emission values for household appliances.

By harmonizing with these documents, EN IEC 60704-2-20:2026 ensures that noise measurement for wet hard floor cleaning appliances remains robust, consistent, and internationally recognized.

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.

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.
