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
IEC 60704-3:2019 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 all parts of IEC 60704-2, which include particular requirements for special categories of appliances. It applies to appliances being produced in quantity, such as in batches, series or lots, which are manufactured to the same technical specification and characterized by the same declared 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;
– specifies a simple statistical method for verifying the declared values by investigating a sample of only three appliances.
This International Standard is to be used in conjunction with IEC 60704-1:2010 and the latest edition of IEC 60704-2 (all parts).
This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition:
a) in Annex A, standard deviations that are now specified for various appliance categories in the parts of IEC 60704-2 have been excluded from Table A.1;
b) furthermore, this edition makes reference to new standards and is implementing ISO/IEC Directives, Part 2 in a more accurate manner.

This third edition cancels and replaces the second edition published in 2006. This edition
constitutes a technical revision. It includes the following significant technical changes with
respect to the previous edition:
a) in Annex A, standard deviations that are now specified for various appliance categories in
the parts of IEC 60704-2 have been excluded from Table A.1;
b) furthermore, this edition makes reference to new standards and is implementing
ISO/IEC Directives, Part 2 in a more accurate manner.
Standard deviations specified in part 2 documents of the IEC 60704 series supersede the
values given in Table A.1.
The text of this International Standard is based on the following documents:
CDV Report on voting
59/675/CDV 59/680A/RVC
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.

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 is 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 describes 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.
Different countries are implementing different market surveillance strategies. This document
is not implementing a mandatory market surveillance strategy.
