50 FOREWORD
51 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
52 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
53 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
54 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
55 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
56 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
57 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
58 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
59 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
60 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
61 consensus of opinion on the relevant subjects since each technical committee has representation from all
62 interested IEC National Committees.
63 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
64 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
65 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
66 misinterpretation by any end user.
67 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
68 transparently to the maximum extent possible in their national and regional publications. Any divergence between
69 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
70 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
71 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
72 services carried out by independent certification bodies.
73 6) All users should ensure that they have the latest edition of this publication.
74 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
75 members of its technical committees and IEC National Committees for any personal injury, property damage or
76 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
77 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
78 Publications.
79 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
80 indispensable for the correct application of this publication.
81 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
82 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
83 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
84 may be required to implement this document. However, implementers are cautioned that this may not represent
85 the latest information, which may be obtained from the patent database available at https://patents.iec.ch shall
86 not be held responsible for identifying any or all such patent rights.
87 IEC 60704-2-1 has been prepared by subcommittee 59F: Surface cleaning appliances, of IEC
88 technical committee 59: Performance of household and similar electrical appliances. It is an
89 International Standard.
90 This fifth edition cancels and replaces the fourth edition published in 2020. This edition
91 constitutes a technical revision.
92 This edition includes the following significant technical changes with respect to the previous
93 edition:
94 a) alignment with IEC 60704-1:2021;

59F/518/CDV – 4 – IEC CDV 60704-2-1 © IEC 2025
95 b) addressing consumer relevant testing aspects;
96 c) robustness of standards and closing potential loop holes

133 INTRODUCTION
134 The measuring conditions specified in this document provide for sufficient accuracy in
135 determining the noise emitted and comparing the results of measurements taken by different
136 laboratories, whilst simulating as far as possible the practical use of vacuum cleaners.
137 It is recommended to consider the determination of noise levels as part of a comprehensive
138 testing procedure covering many aspects of properties and performance of household vacuum
139 cleaners.
140 NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.
