41 FOREWORD
42 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
43 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
44 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
45 in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to
46 technical committees; any IEC National Committee interested in the subject dealt with may participate in this
47 preparatory work. International, governmental and non-governmental organizations liasing with the IEC also
48 participate in this preparation. The IEC collaborates closely with the International Organization for
49 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
50 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
51 international consensus of opinion on the relevant subjects since each technical committee has representation
52 from all interested National Committees.
53 3) The documents produced have the form of recommendations for international use and are published in the form
54 of standards, technical specifications, technical reports or guides and they are accepted by the National
55 Committees in that sense.
56 4) In order to promote international unification, IEC National Committees undertake to apply IEC International
57 Standards transparently to the maximum extent possible in their national and regional standards. Any divergence
58 between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the
59 latter.
60 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
61 equipment declared to be in conformity with one of its standards.
62 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
63 of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
64 International Standard IEC 60704-2-9 has been prepared by subcommittee 59L: small
65 appliances, of IEC technical committee 59: Performance of household electrical appliances.
66 The text of this publication is based on the following documents:
FDIS Report on Voting
59L/XXX/FDIS 59L/XXX/RVD
68 Full information on the voting for the approval of this standard can be found in the report on
69 voting indicated in the above table.
70 This publication has been drafted in accordance with ISO/IEC Directives, Part 2.
71 IEC 60704 consists of the following parts, under the general title Test code for the determination
72 of airborne acoustical noise:
73 Part 1: General requirements
74 Part 2: Particular requirements
75 Part 3: Procedure for determining and verifying declared noise emission values
76 This part 2-9 is intended to be used in conjunction with the fourth edition of IEC 60704-1:2021:
77 Household and similar electrical appliances – Test code for the determination of airborne
78 acoustical noise – Part 1: General requirements.
