IEC 60704-2-2:2009

Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 2-2: Particular requirements for fan heaters

IEC 60704-2-2:2009 provides the methods of determination of airborne acoustical noise emitted by electric fan heaters, designed for placing on the floor, table or counter,etc., or for wall mounting supplied from mains or from batteries. The main changes from the previous edition are as follows: provisions with regard to measurement uncertainty and standard deviation for declaration and verification have been included in the scope.
This publication is to be read in conjunction with IEC 60704-1:2010.

Appareils électrodomesiques et analogues - Code d'essai pour la détermination du bruit aérien - Partie 2-2: Exigences particulières pour les appareils de chauffage soufflants

La CEI 60704-2-2:2009 fournit la méthode pour la détermination du bruit aérien émis par les appareils de chauffage soufflants électriques, conçus pour être placés sur le sol, sur une table ou sur un plan de travail, etc., ou pour être fixés au mur. Les principales modifications de la présente édition par rapport à l'édition précédente sont l'addition des dispositions pour les incertitudes de mesure, ainsi que des écarts types pour la déclaration et la vérification.
Cette publication doit être lue conjointement avec la CEI 60704-1:2010.

Part 2-2: Particular requirements for fan heaters

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60704-2-2 has been prepared by subcommittee 59C: Heating
appliances, of IEC technical committee 59: Performance of household and similar electrical
appliances.
This second edition cancels and replaces the first edition published in 1985 and constitutes a
technical revision. The main changes from the previous edition are as follows: provisions with
regard to measurement uncertainty and standard deviation for declaration and verification
have been included in the scope.

This publication has been drafted in accordance with ISO/IEC Directives, Part 2.

This part 2-2 is intended to be used in conjunction with IEC 60704-1, 2nd edition 1997:
Household and similar electrical appliances – Test code for the determination of airborne
acoustical noise – Part 1: General requirements.
The relevant text of part 1 as amended by this publication establishes the test code for fan
heaters.
This part 2-2 supplements or modifies the corresponding clauses in IEC 60704-1:1997. When
a particular subclause of part 1 is not mentioned in this part 2-2, that subclause applies as far
as reasonable. Where this standard states "addition“, "modification“ or "replacement“, the
relevant requirement, test specifications or explanatory matter in part 1 shall be adapted
accordingly.
