12 FOREWORD
13 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
14 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
15 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
16 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
17 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
18 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
19 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
20 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
21 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
22 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
23 consensus of opinion on the relevant subjects since each technical committee has representation from all
24 interested IEC National Committees.
25 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
26 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
27 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
28 misinterpretation by any end user.
29 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
30 transparently to the maximum extent possible in their national and regional publications. Any divergence between
31 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
32 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
33 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
34 services carried out by independent certification bodies.
35 6) All users should ensure that they have the latest edition of this publication.
36 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
37 members of its technical committees and IEC National Committees for any personal injury, property damage or
38 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
39 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
40 Publications.
41 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
42 indispensable for the correct application of this publication.
43 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
44 rights. IEC shall not be held responsible for identifying any or all such patent rights.
45 International Standard IEC 60704-2-4 has been prepared by subcommittee 59D: Home laundry
46 appliances, of IEC technical committee 59: Performance of household and similar electrical
47 appliances.
48 This fourth edition cancels and replaces the third edition (2011). Main changes are:
49 • Alignment to IEC 60704-1:2021
50 • Alignment to Edition 6 of IEC 60456:20xx (document 59D/507/CDV), especially regarding
51 test program and detergent
52 • Considering multi-compartment washing machines
53 • Considering wall-mounted washing machines
54 • Definition of the drum speed measurement
55 • Adapting parts for standard test load and test programme

59 Full information on the voting for the approval of this standard can be found in the report on
60 voting indicated in the above table.
61 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
62 This document is intended to be used in conjunction with the fourth edition of IEC 60704-1:2021,
63 Household and similar electrical appliances – Test code for the determination of airborne
64 acoustical noise – Part 1: General requirements.
65 The relevant text of IEC 60704-1:2021 as amended by this document establishes the test code
66 for washing machines and spin extractors.
67 This document supplements or modifies the corresponding clauses in IEC 60704-1:2021. When
68 a particular subclause of IEC 60704-1:2021 is not mentioned in this document, that subclause
69 is applicable as far as reasonable. Where this standard states "addition", "modification" or
70 "replacement", the relevant requirements, test specifications or explanatory matter in IEC
71 60704-1:2021 should be adapted accordingly.
72 Subclauses, tables and figures that are additional to those in IEC 60704-1:2021 are numbered
73 starting from 101. Additional annexes are lettered AA, BB, etc.
74 Unless notes are in a new subclause or involve notes in IEC 60704-1:2021, they are numbered
75 starting from 101, including those in a replaced clause or subclause.
76 A list of all the parts in the IEC 60704 series, under the general title Household and similar
77 electrical appliances – Test code for the determination of airborne acoustical noise, can be
