33 Part 2-7: Particular requirements for fans
35 FOREWORD
36 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
37 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
38 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
39 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
40 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
41 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
42 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
43 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
44 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
45 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
46 consensus of opinion on the relevant subjects since each technical committee has representation from all
47 interested IEC National Committees.
48 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
49 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
50 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
51 misinterpretation by any end user.
52 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
53 transparently to the maximum extent possible in their national and regional publications. Any divergence between
54 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
55 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
56 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
57 services carried out by independent certification bodies.
58 6) All users should ensure that they have the latest edition of this publication.
59 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
60 members of its technical committees and IEC National Committees for any personal injury, property damage or
61 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
62 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
63 Publications.
64 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
65 indispensable for the correct application of this publication.
66 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
67 rights. IEC shall not be held responsible for identifying any or all such patent rights.
68 International Standard IEC 60704-2-7 has been prepared by subcommittee 59L: Small
69 household appliances, of IEC technical committee 59: Performance of household and similar
70 electrical appliances.
71 This third edition cancels and replaces the second edition published in 2020. This edition
72 constitutes a technical revision.
73 This edition includes the following significant changes with respect to the previous edition:
74 a) it has been adjusted with regard to IEC 60704-1:2021;
75 b) Scope has been expanded to handheld, neckband and embedded fans.
76 c) Positioning and mounting reworked
77 d) Test concept of partition ventilating fans changed to measuring both inlet and outlet side
78 together

CDV Report on voting
xxx/xxx/xxx xxx/xxx/xxx
81 Full information on the voting for the approval of this standard can be found in the report on
82 voting indicated in the above table.
83 This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
84 A list of all parts in the IEC 60704 series, published under the general title Household and
85 similar electrical appliances – Test code for the determination of airborne acoustical noise, can
86 be found on the IEC website.
87 This International Standard is to be used in conjunction with IEC 60704-1:2021, Household and
88 similar electrical appliances – Test code for the determination of airborne acoustical noise –
89 Part 1: General requirements.
90 .
91 The relevant text of IEC 60704-1:2021 as amended by this standard establishes the test code
92 for fans.
93 This Part 2-7 supplements or modifies the corresponding clauses in IEC 60704-1:2021, so as
94 to establish the test code for fans. When a particular subclause of IEC 60704-1:2021 is not
95 mentioned in this Part 2-7, that subclause is applicable as far as reasonable. Where this
96 standard states "addition", "modification" or "replacement", the relevant requirements, test
97 specifications or explanatory matter in IEC 60704-1:2021 shall be adapted accordingly.
98 Subclauses, tables and figures that are numbered starting from 101 are additional to those
99 inIEC 60704-1:2021.
100 Unless notes are in a new subclause or involve notes in IEC 60704-1:2021, they are numbered
101 starting from 101, including those in a replaced clause or subclause.
