10 FOREWORD
11 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
12 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
13 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
14 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
15 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
16 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
17 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
18 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
19 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
20 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
21 consensus of opinion on the relevant subjects since each technical committee has representation from all
22 interested IEC National Committees.
23 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
24 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
25 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
26 misinterpretation by any end user.
27 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
28 transparently to the maximum extent possible in their national and regional publications. Any divergence between
29 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
30 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
31 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
32 services carried out by independent certification bodies.
33 6) All users should ensure that they have the latest edition of this publication.
34 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
35 members of its technical committees and IEC National Committees for any personal injury, property damage or
36 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
37 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
38 Publications.
39 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
40 indispensable for the correct application of this publication.
41 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
42 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
43 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
44 may be required to implement this document. However, implementers are cautioned that this may not represent
45 the latest information, which may be obtained from the patent database available at https://patents.iec.ch.
46 IEC shall not be held responsible for identifying any or all such patent rights.
49 IEC 60704-2-20 has been prepared by subcommittee 59F: Surface cleaning appliances, of
50 IEC technical committee 59: Performance of household and similar electrical appliances. It is
51 an International Standard.
52 The text of this International Standard is based on the following documents:
Draft Report on voting

54 Full information on the voting for its approval can be found in the report on voting indicated in
55 the above table.
56 The language used for the development of this International Standard is English.
57 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
58 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
59 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
60 described in greater detail at www.iec.ch/publications.
61 This Part 2-20 is intended to be used in conjunction with IEC 60704-1:2021, Household and
62 similar electrical appliances – Test code for the determination of airborne acoustical noise –
63 Part 1: General requirements.
64 NOTE When "Part 1" is mentioned in this standard, it refers to IEC 60704-1:2021.
65 The relevant text of Part 1 as amended by this document establishes the test code for wet hard
66 floor cleaners.
67 This Part 2-20 supplements or modifies the corresponding clauses in IEC 60704-1:2021. When
68 a particular subclause of Part 1 is not mentioned in this Part 2-20, that subclause is applicable
69 as far as reasonable. Where this standard states "addition", "modification" or "replacement",
70 the relevant requirements, test specifications or explanatory matter in Part 1 should be adapted
71 accordingly.
72 Subclauses, tables, and figures that are additional to those in Part 1 are numbered starting from
73 101. Additional annexes are lettered AA, BB, etc.
74 Unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from
75 101, including those in a replaced clause or subclause.
76 A list of all the parts in the IEC 60704 series, published under the general title Household and
77 similar electrical appliances – Test code for the determination of airborne acoustical noise, can
78 be found on the IEC website.
79 The committee has decided that the contents of this document will remain unchanged until the
80 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
81 specific document. At this date, the document will be
82 • reconfirmed,
83 • withdrawn,
84 • replaced by a revised edition, or
85 • amended.

88 INTRODUCTION
89 The measuring conditions specified in this part of IEC 60704 provide for sufficient accuracy in
90 determining the noise emitted and comparing the results of measurements taken by different
91 laboratories, whilst simulating as far as possible the practical use of wet hard floor cleaners.
92 It is recommended to consider the determination of noise levels as part of a comprehensive
93 testing procedure covering many aspects of properties and performance of household wet hard
94 floor cleaners.
95 NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.
