Beskrivelse

This International Standard specifies all the information necessary to carry out efficiently and under
standardized conditions the determination, declaration, and verification of the airborne noise emission
of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating
and mounting conditions that shall be used for the test.
Noise emission characteristics include emission sound pressure levels at specified positions and the
sound power level. The determination of these quantities is necessary for
– declaring the noise emission values, and
– purpose of noise control at source at the design stage.
The determination of these quantities is also necessary for comparing the noise emitted by liquid
pumps on the market.
The use of this International Standard ensures the reproducibility of the determination of the airborne
noise-emission characteristics within specified limits determined by the grade of accuracy of the basic
airborne noise measurement method used. Noise measurement methods according to this International
Standard are engineering methods (grade 2) and survey methods (grade 3).
This International Standard does not deal with the characterization of the structure-borne sound and
liquid-borne noise generated by liquid pumps.
NOTE – This International Standard is specified in EN 809+A1 for noise measurements of the Pump (or
Pump Unit).
