标准范围

This International Standard specifies all the information necessary to carry out efficiently and understandardized conditions the determination, declaration, and verification of the airborne noise emissionof liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operatingand mounting conditions that shall be used for the test.Noise emission characteristics include emission sound pressure levels at specified positions and thesound 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 pumpson the market.The use of this International Standard ensures the reproducibility of the determination of the airbornenoise-emission characteristics within specified limits determined by the grade of accuracy of the basicairborne noise measurement method used. Noise measurement methods according to this InternationalStandard are engineering methods (grade 2) and survey methods (grade 3).This International Standard does not deal with the characterization of the structure-borne sound andliquid-borne noise generated by liquid pumps.
