Household and similar electrical appliances - Test code for the determination of airborne acoustical noise -- Part 3: Procedure for determining and verifying declared noise emission values
This part of IEC 60704 describes procedures for determining and verifying the declared values of the noise emitted by household and similar appliances. It applies to all categories of household and similar electrical appliances covered by IEC 60704-1 and IEC 60704-2 dealing with particular requirements for special categories of appliances. It applies to appliances being produced in quantity (in series, batches, lots) manufactured to the same technical specification and characterized by the same labeled value of noise emission. This part of IEC 60704 considers the term "declaration" to include all means for providing information on the noise emission values to potential users (consumers) of the appliances; this includes labels, brochures, advertisements, commercial and technical information papers, etc.; - considers the declaration for appliances manufactured by mass production, with the same declared value for the lot (batch); - specifies a simple statistical method for verifying the declared values by investigating a sample of only three appliances.

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 60704-3 has been prepared by IEC technical committee 59:
Performance of household electrical appliances.
This second edition cancels and replaces the first edition published in 1992 and constitutes a
technical revision. Major changes in this second edition involve revised values in Table A.1,
including added values for fans and ovens and designation of values for standard deviations
of production as informative rather than normative. Additionally, it was determined that
standard deviations specified in part 2 documents of the IEC 60704 series supersede the
values given in Table A.1.

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 3 of IEC 60704 is intended to be used in conjunction with the latest edition of
IEC 60704-1 and IEC 60704-2. It was established on the basis of the second edition (1997) of
IEC 60704-1.
IEC 60704 consists of the following parts, under the general title Household and similar
electrical appliances – Test code for the determination of airborne acoustical noise:
Part 1 General requirements
Part 2-1 Particular requirements for vacuum cleaners
Part 2-2 Particular requirements for forced draught convection heaters
Part 2-3 Particular requirements for dishwashers
Part 2-4 Particular requirements for washing machines and spin extractors
Part 2-5 Particular requirements for electric thermal storage room heaters
Part 2-6 Particular requirements for tumble dryers
Part 2-7 Particular requirements for fans
Part 2-8 Particular requirements for electric shavers
Part 2-9 Particular requirements for electric hair care appliances
Part 2-10 Particular requirements for electric cooking ranges, ovens, grills, microwave
ovens and any combination of these
Part 2-11 Particular requirements for electrically operated food preparation
Part 2-13 Particular requirements for range hoods
Part 3 Procedure for determining and verifying declared noise emission values
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or

INTRODUCTION
Although the noise levels produced by household appliances are not known to present
a hazard to the hearing of users or other exposed persons, and as a result no noise limits
have been specified by relevant authorities responsible for health protection, a
comprehensive and correct declaration of noise emission will be very helpful to enable the
potential buyer to make a good choice between appliances of the same category (serving for
the same purpose) of different makes or for different models.
In order to ensure a correct declaration of noise emission values, this part of IEC 60704
prescribes a simple method for verifying declared values and provides information for
determining the noise emission values.
The necessary measurements are carried out according to the relevant parts of IEC 60704.

Part 3: Procedure for determining and verifying
declared noise emission values
1 Scope
This part of IEC 60704 describes procedures for determining and verifying the declared
values of the noise emitted by household and similar appliances.
It applies to all categories of household and similar electrical appliances covered by
IEC 60704-1 and IEC 60704-2 dealing with particular requirements for special categories of
appliances.
It applies to appliances being produced in quantity (in series, batches, lots) manufactured to
the same technical specification and characterized by the same labeled value of noise
emission.
This part of IEC 60704
− considers the term "declaration" to include all means for providing information on the
noise emission values to potential users (consumers) of the appliances; this includes
labels, brochures, advertisements, commercial and technical information papers, etc.;
− considers the declaration for appliances manufactured by mass production, with the same
declared value for the lot (batch);
− specifies a simple statistical method for verifying the declared values by investigating a
sample of only three appliances.
