Overview

EN IEC 60704-2-1:2020 (also published as IEC 60704-2-1:2020) is the Part 2-1 test code for the determination of airborne acoustical noise emitted by dry vacuum cleaners intended for household or similar use. This fourth edition updates the previous 2014 version and is intended to be used together with IEC 60704-1:2010 (Part 1: General requirements). It defines measurement conditions and particular requirements to produce reproducible sound pressure and sound power level results for mains-operated and cordless vacuum cleaners. The standard excludes industrial or professional vacuum cleaners.

Key Topics

• Scope and object: Applies to household dry vacuum cleaners (mains and cordless) and does not cover industrial/professional appliances.
• Measurement methods: Permits use of established engineering methods such as ISO 3743-1, ISO 3743-2 and ISO 3744 for determining sound power and sound pressure.
• Definitions added: New definitions for terms like cleaning head, active nozzle and standard Wilton test carpet to clarify test configurations.
• Test material and reference: The explicit specification for the standard Wilton test carpet was removed from this edition and reference is made to IEC/TS 62885-1 for test material and equipment.
• Equipping and pre-conditioning: New requirements on how to equip appliances for test (accessories, nozzles, hoses) and pre-condition them prior to measurement to ensure consistent results.
• Ageing of test carpet: The standard addresses the effect of test carpet ageing and related handling to maintain measurement validity.
• Reporting and uncertainty: Specifies information to be recorded and reported, and addresses measurement uncertainty and statistical deviations for declaration and verification.

Applications

EN IEC 60704-2-1:2020 is used by:

• Manufacturers and product developers for acoustic design, benchmarking and optimizing vacuum cleaner noise performance.
• Independent test laboratories for standardized noise testing and sound power level determination.
• Compliance and certification bodies when assessing conformity with noise-related product requirements.
• Procurement teams and retailers who require comparable noise data for product selection.
• Acoustical engineers and R&D teams conducting validation tests, quality control and comparative testing across models (including cordless designs).

Practical outcomes include consistent measurement data for product labeling, design improvement, regulatory compliance and consumer information on vacuum cleaner noise levels.

Related Standards

• IEC 60704-1:2010 - Part 1: General requirements (to be used in conjunction)
• IEC/TS 62885-1 - Surface cleaning appliances: test material and equipment (referenced for test carpet)
• ISO 3743-1, ISO 3743-2, ISO 3744 - Accepted acoustics methods for sound power/pressure testing
• Other parts of the IEC 60704 series covering different appliance types and test conditions

Keywords: EN IEC 60704-2-1:2020, vacuum cleaners, airborne acoustical noise, test code, cordless vacuum, noise measurement, sound power level, IEC 60704-1.

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 60704-2-1 has been prepared by subcommittee 59F: Surface
cleaning appliances, of IEC technical committee 59: Performance of household and similar
electrical appliances.
This fourth edition cancels and replaces the third edition published in 2014. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous

a) product scope is extended to cordless and similar vacuum cleaners;
b) definitions of "cleaning head", "active nozzle" and "standard Wilton test carpet" have been
added;
c) specification of standard Wilton test carpet has been removed; reference is made to
IEC TS 62885-1;

INTRODUCTION
The measuring conditions specified in this part of IEC 60704 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 vacuum 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 vacuum
cleaners.
NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.
