1.1 Scope
1.1.1 General
This test code for the determination of airborne acoustical noise applies to household
appliances (including their accessories or components) for household and similar use,
supplied from mains or from batteries.
“Household appliances” designate equipment intended for housekeeping functions such
as washing, cleaning, heating, cooling, cooking, etc and appliances intended for use
by users in the home environment such as shavers, hair care appliances, food preparation
appliances etc..
By similar use is understood the use by non expert users in similar conditions as
in households, for example:
-
– in shops, offices or other similar work environments;
-
– in farm houses;
-
– by clients in hotels, motels and other residential type environments;
-
– in bed and breakfast type environments.
This European Standard does not apply to
-
– appliances for commercial use,
-
– household appliances which are integrated parts of a building or its installations, such as equipment for air conditioning, heating and ventilating (except household fans, cooker hoods and free standing heating appliances), oil burners for central heating, pumps for water supply and for sewage systems,
-
– separate motors or generators,
-
– appliances for outdoor use.
Appliances for commercial use designate equipment to be used by persons that have
been trained on the use of such appliances and appliances and machines which are declared
to be for commercial use by laypersons.
This European Standard does not deal with safety requirements.
1.1.2 Types of noise
A classification of different types of noise is given in ISO 12001. The method specified
in ISO 3744 is suitable for measurements of all types of noise emitted by household
appliances. The methods specified in ISO 3743-1 and ISO 3743-2 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 2.
1.1.3 Size of the source
The method specified in ISO 3744 is applicable to noise sources of any size. Limitations
for the size of the source are given in 1.3 of ISO 3743-1 and ISO 3743-2. This will be taken into account in the preparation
of parts 2.
