TEST CODE FOR THE DETERMINATION
OF AIRBORNE ACOUSTICAL NOISE –
Part 2-1: Particular requirements for dry vacuum cleaners
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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change has
been made. Additions are in green text, deletions are in strikethrough red text.

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
edition:
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;
d) specific requirements on equipping and pre-conditioning have been added;
e) topic ageing of test carpet is addressed.
The text of this International Standard is based on the following documents:
FDIS Report on voting
59F/399/FDIS 59F/408/RVD
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 2-1 is intended to be used in conjunction with IEC 60704-1:2010, Household and
similar electrical appliances – Test code for the determination of airborne acoustical noise –
Part 1: General requirements.
NOTE When "Part 1" is mentioned in this standard, it refers to IEC 60704-1:2010.
The relevant text of Part 1 as amended by this document establishes the test code for vacuum
cleaners.
This Part 2-1 supplements or modifies the corresponding clauses in IEC 60704-1:2010. When
a particular subclause of Part 1 is not mentioned in this Part 2-1, 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 Part 1 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.
A list of all the 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 "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.
