INTRODUCTION to IEC 60704-1:2021
Although the noise emitted by household appliances does not generally present a hazard to
the hearing of the operator and other exposed persons, the need for standardization
procedures for the determination of the noise emitted has been recognized for a long time.
Such procedures should be specified, not only for special types of appliances, but also the
principles should be applicable to the majority of appliances in general use.
Generally, the determination of noise levels is only part of a comprehensive testing procedure
covering many aspects of the properties and performances of the appliance. It is therefore
important that the requirements for noise measurements (such as test environment,
instrumentation, and amount of labour involved) be kept at a modest level.
The results of noise measurements are used for many purposes, for example for noise
declaration, as well as for comparing the noise emitted by a specific appliance to the noise
emitted by other appliances of the same family. In other cases, the results are taken as a
basis for engineering action in the development stages of new pieces of equipment, or in
deciding on means for sound insulation. For all purposes, it is important to specify procedures
with known accuracy so that the results of measurements taken by different laboratories can
be compared.
These conditions have, as far as possible, been taken into account in the preparation of this
test code. The acoustic measuring methods are based on those described in
ISO 3743‑1:2010, ISO 3743-2:2018 and ISO 3744:2010.
The adoption of these methods permits the use of hemi-anechoic rooms, special reverberation
test rooms and hard-walled test rooms. The result of the measurements is the sound power
level of the appliance. Within the measuring uncertainty specific to these methods, the results
from the determination under free field conditions over a reflecting plane are equal to those
obtained in reverberant fields.
The use of intensity methods as described in ISO 9614-1:1993, ISO 9614-2:1996, and
ISO 9614-3:2002 is applicable under special conditions, which are described in specific parts
of the IEC 60704-2 series.
This test code is concerned with airborne noise only. In some cases, structure-borne noise,
for example transmitted to the adjoining room, can be of importance.

INTRODUCTION to IEC 60704-2-1:2026
The measuring conditions specified in this document provide for sufficient accuracy in
determining the noise emitted and comparing the results of measurements taken by different
laboratories, whilst simulating as far as possible the practical use of dry vacuum cleaners.
It is recommended to consider the determination of noise levels as part of a comprehensive
testing procedure covering many aspects of properties and performance of household vacuum
cleaners.
NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.

1 Scope
This part of IEC 60704 applies to electric appliances (including their accessories or
components) for household and similar use, supplied from mains or from batteries.
By "similar use" is understood the use in conditions similar to those found in households, for
example in inns, coffee houses, tea rooms, hotels, barber or hairdresser shops, launderettes,
etc., if not otherwise specified in the IEC 60704-2 series.

4 Measurement methods and acoustical environments
4.1 General
This document is concerned with objective methods of engineering accuracy grade 2 in
accordance with ISO 12001:1996 for determining sound power levels L , expressed in
W
decibels (dB), with reference to a sound power of one picowatt (1 pW), of airborne acoustical
noise within the specified frequency range of interest (generally including the octave-bands
with centre frequencies from 125 Hz to 8 000 Hz), and for prescribed operating conditions of
the appliance to be measured.
Methods for determining sound power levels with precision accuracy grade 1 in accordance
with ISO 12001:1996, as specified for example in ISO 3741 and ISO 3745, are not included in
this document. They may, however, be applied if the appropriate test environment and
instrumentation are available.
NOTE 1 The noise values obtained under the described conditions of this document will not necessarily
correspond to the noise experienced under the operational conditions of practical use.
NOTE 2 For quality control during production etc., simplified methods can be appropriate. For noise reduction
purposes, other measurement methods employing, for example, narrow-band analysis or intensity techniques
usually have to be applied. These methods are not covered by this document.
The total noise emitted by machinery or equipment and radiated in all directions to the space
surrounding the machine can be characterized by the sound power of the machine. Within the
accuracy range of this document, the sound power of a machine is basically independent of
the environment in which the machine is installed
Therefore, the concept of sound power level has been chosen for expressing the noise
emission of appliances for household and similar purposes.
The preferred noise emission quantity is the A-weighted sound power level, L , in dB
WA
(re 1 pW).
According to this document, two principal methods exist, the direct method and the
comparison method, as described in 4.2 and 4.3. These two methods can be used
alternatively.
Different types of environments, as described in 4.4, may be used. A part of the IEC 60704-2
series may, if necessary, exclude one or several combinations among those available.
4.2 Direct method
The direct method can be used only for measurements in qualified test environments in
accordance with ISO 3744:2010 for free field conditions over reflecting plane(s), and in
accordance with ISO 3743-2:2018 for special reverberation test rooms.
With this method, the sound power level is determined
– in free field conditions over reflecting plane(s), from time-averaged sound pressure levels
(on a mean-square basis) over the measurement surface and from the area of the
measurement surface, S, or
– in reverberation and special reverberation test rooms, from averaged sound pressure
levels, and from the reverberation time and the volume of the test room.
If for a measurement in a free field, reverberation or special reverberation room is not
possible because the appliance cannot be placed or operated in such an environment, the
intensity method in accordance with ISO 9614-1:1993, ISO 9614-2:1996, and ISO 9614-
3:2002 shall be applied. For the intensity method, the standard deviations given in the parts of
the IEC 60704-2 series and IEC 60704-3:2019 are not applicable unless stated explicitly.
These methods yield results expressed in A-weighted sound power levels (and in octave- or
1/3 octave-band sound power levels, if required) that are calculated directly from measured
sound pressure levels.
NOTE This method can also be used in conjunction with more precise methods, such as those given in ISO 3741
and ISO 3745.
If audible discrete tones are present in the noise emitted by the source, the estimated
standard deviation of the measured sound pressure levels in the special reverberation room
can increase. In such cases, additional microphone positions or source positions can be
necessary, as specified in ISO 3743-2.
If an operator is necessary, it is considered as part of the test environment. Therefore, the
operator shall be present also during the reverberation time measurement with the RSS. The
position of the operator shall be approximately at the same position as in the measurement
with the test sample.
4.3 Comparison method
The comparison method for measurement is explicitly described in ISO 3743-1:2010 and in
ISO 3743-2:2018.
NOTE The term "comparison method" is not explicitly given in ISO 3744:2010, but when applying the "absolute
comparison test" for the determination of the environmental correction given in A.3 of ISO 3744:2010, by using a
reference sound source, the procedure is, in fact, a comparison method.
With this method, the sound power level is determined by comparing the averaged values (on
a mean-square basis) of the sound pressure levels produced by the source in the test room to
the averaged values of the sound pressure levels produced in the same room by a calibrated
reference sound source (RSS) of known sound power output, complying with the requirements
of ISO 6926:2016. The difference in sound pressure levels is equal to the difference in sound
power levels when conditions are the same for both sets of measurements.
This method yields results expressed in octave- or 1/3 octave-band sound power levels, and
the A-weighted sound power level is calculated from the octave- or 1/3 octave-band sound
power levels.
To check whether there is a systematic difference between results obtained in different
environments, the use of the comparison method is recommended.
If audible discrete tones are present in the noise emitted by the source, the estimated
standard deviation of the measured sound pressure levels in the hard-walled test room or in
the special reverberation room can increase. In such cases, additional microphone positions
or source positions can be necessary, as specified in ISO 3743-1 or ISO 3743-2.
If an operator is necessary, it is considered as part of the test environment. Therefore, the
operator shall be present also during the comparison measurement with the RSS. The
position of the operator shall be approximately at the same position as in the measurement
with the test sample.
4.4 Acoustical environments
4.4.1 General requirements and criterion for adequacy of the test environment
They are given in the following clauses:
– Clause 4 of ISO 3743-1:2010 for hard-walled test rooms;
– Clause 5 of ISO 3743-2:2018 for special reverberation test rooms and
– Clause 4 of ISO 3744:2010 for free-field conditions over a reflecting plane.
A classification of different types of noise is given in ISO 12001:1996. The method specified
in ISO 3744:2010 is suitable for measurements of all types of noise emitted by household
appliances. The methods specified in ISO 3743-1:2010 and ISO 3743-2:2018 are suitable for
all types of noise, except for sources of impulsive noise consisting of short-duration noise
bursts. This will be taken into account in the preparation of parts of the IEC 60704-2 series.
The method specified in ISO 3744:2010 is applicable to noise sources of any size. Limitations
for the size of the source are given in 4.2 of ISO 3743-1:2010 and in Clause 5 of
ISO 3743-2:2018. This will be taken into account in the preparation of parts of the
IEC 60704-2 series.
NOTE For free-field conditions over a reflecting plane, the absolute comparison test for the qualification of the
environment, described in Clause A.2 of ISO 3744:2010, is preferred.
Guidelines for the design of simple test rooms with free-field conditions are given in Annex C.
Guidelines for the design of a suitable special reverberation test room are given in
ISO 3743-2:2018, Annex A.
The methods specified in ISO 3743-1, ISO 3743-2 and ISO 3744 can be used for measuring
noise emitted by electric vacuum cleaners.
4.4.2 Criterion for background noise level
Requirements for the background noise level are given in 4.5 of ISO 3743-1:2010, in 6.5 of
ISO 3743-2:2018 and in 4.2 of ISO 3744:2010. Averaged over the microphone positions, the
background noise level shall be at least 6 dB below, and preferably more than 15 dB below,
the sound pressure level to be measured.
NOTE If the difference between the sound pressure levels of the background noise and the appliance noise is
less than 6 dB, see 8.2.
4.4.3 Environmental conditions
Environmental conditions having an adverse effect on the microphone used for the
measurements (for example, strong electric or magnetic fields, wind, impingement of air
discharge from the equipment being tested, high or low temperatures) shall be avoided by
proper selection or positioning of the microphone.
The instructions of the manufacturers of the measurement instruments regarding adverse
environmental conditions shall be followed. The microphone shall always be oriented in such
a way that the angle of incidence of the sound waves is that for which the microphone is
calibrated.
4.5 Measurement uncertainties
4.5.1 General
The estimated values of the standard deviations of reproducibility of sound power levels
determined in accordance with this document are given in 9.1 of ISO 3743-1:2010, in 11.1 of
ISO 3743‑2:2018 and in 9.1 of ISO 3744:2010. But for a particular family of appliances of
similar size with similar operating conditions, the standard deviations of reproducibility can be
smaller than these values. Hence, in the IEC 60704-2 series, standard deviations smaller than
those listed in ISO standards can be stated if substantiation is available from the results of
suitable interlaboratory tests.
In the case of discrepancies between the measurements where the results normally remain
inside the foreseen standard deviation, it can be helpful to perform measurements according
to the upper grade of accuracy: grade 1, laboratory or precision, as described in ISO 3741 or
ISO 3745.
4.5.2 Standard deviations on repeatability and reproducibility and standard
deviations related to declaration and verification
For dry vacuum cleaners designed for cleaning carpets, the estimated values of standard
deviations of sound power levels determined in accordance with this document are provided
in Table 1.
Table 1 – Standard deviations of sound power levels determined on carpets

4 Measurement methods and acoustical environments
4.2 Direct method
Addition:
If audible discrete tones are present in the noise emitted by the source, the estimated standard
deviation of the measured sound pressure levels in the special reverberation room can increase.
In such cases, additional microphone positions or source positions can be necessary, as
specified in ISO 3743-2.
If an operator is necessary, it is considered as part of the test environment. Therefore, the
operator shall be present also during the reverberation time measurement with the RSS. The
position of the operator shall be approximately at the same position as in the measurement with
the test sample.
4.3 Comparison method
Addition:
If audible discrete tones are present in the noise emitted by the source, the estimated standard
deviation of the measured sound pressure levels in the hard-walled test room or in the special
reverberation room can increase. In such cases, additional microphone positions or source
positions can be necessary, as specified in ISO 3743-1 or ISO 3743-2.
If an operator is necessary, it is considered as part of the test environment. Therefore, the
operator shall be present also during the comparison measurement with the RSS. The position
of the operator shall be approximately at the same position as in the measurement with the test
sample.

INTRODUCTION
Les conditions de mesure spécifiées dans le présent document sont prévues pour assurer une
exactitude suffisante pour la détermination du bruit émis et la comparaison des résultats de
mesures obtenus par différents laboratoires tout en simulant, dans la mesure du possible,
l'utilisation pratique des aspirateurs à sec.
Il est recommandé de prendre en considération la détermination des niveaux de bruit comme
faisant partie d'une procédure d'essai complète qui couvre de nombreux aspects des
caractéristiques et des performances des aspirateurs à usage domestique.
NOTE Comme cela est indiqué dans l'introduction de l'IEC 60704-1, ce code d'essai concerne uniquement le bruit
aérien.
1 Domaine d'application
Addition:
Le présent document spécifie la détermination du bruit aérien des aspirateurs à sec qui
fonctionnent sur secteur et des aspirateurs à sec sans cordon, y compris leurs accessoires et
les stations d'accueil, destinés à un usage domestique ou dans des conditions analogues à
celles des foyers domestiques.
Pour les aspirateurs humides et à sec, la fonction de nettoyage à sec s'applique. La fonction
de nettoyage avec de l'eau est mesurée conformément à l'IEC 60704-2-20.
NOTE 101 Les exigences particulières pour les robots de nettoyage humide sont spécifiées dans
l'IEC 60704-2-17 .

4 Méthodes de mesure et environnements acoustiques
4.2 Méthode directe
Addition:
Si le bruit émis par la source comporte des sons purs audibles, l'écart-type estimé des niveaux
de pression acoustique mesurés dans la salle réverbérante spéciale peut augmenter. Dans de
tels cas, des positions de microphones ou des positions de sources supplémentaires peuvent
être nécessaires, comme cela est spécifié dans l'ISO 3743-2.
Si un opérateur est nécessaire, il est considéré comme faisant partie de l'environnement
d'essai. Par conséquent, l'opérateur doit également être présent pendant le mesurage du temps
de réverbération avec la RSS. La position de l'opérateur doit être située approximativement à
la même position utilisée pour le mesurage avec l'échantillon d'essai.
4.3 Méthode de comparaison
Addition:
Si le bruit émis par la source comporte des sons purs audibles, l'écart-type estimé des niveaux
de pression acoustique mesurés dans la salle d'essai à parois dures ou dans la salle
réverbérante spéciale peut augmenter. Dans de tels cas, des positions de microphones ou des
positions de sources supplémentaires peuvent être nécessaires, comme cela est spécifié dans
l'ISO 3743-1 ou l'ISO 3743-2.
Si un opérateur est nécessaire, il est considéré comme faisant partie de l'environnement
d'essai. Par conséquent, l'opérateur doit être présent pendant le mesurage comparatif avec la
RSS. La position de l'opérateur doit être située approximativement à la même position utilisée
pour le mesurage avec l'échantillon d'essai.
4.4 Environnement acoustique
4.4.1 Exigences générales et critère d'adéquation avec l'environnement d'essai
Addition:
Les méthodes spécifiées dans l'ISO 3743-1, l'ISO 3743-2 et l'ISO 3744 peuvent être utilisées
