适用范围:This International Standard specifies all the information necessary to carry out efficiently and understandardized conditions the determination, declaration and verification of the airborne noise emission of liquidpumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mountingconditions that shall be used for the test.Noise emission characteristics include emission sound pressure levels at specified positions and the soundpower level. The determination of these quantities is necessary for- declaring the noise emission values,- purpose of noise control at source at the design stage.NOTE 1 The determination of these quantities is also necessary for comparing the noise emitted by liquid pumps on themarket.The use of this International Standard ensures the reproducibility of the determination of the airborne noiseemissioncharacteristics within specified limits determined by the grade of accuracy of the basic airborne noisemeasurement method used. Noise measurement methods according to this International Standard areengineering methods (grade 2) and survey methods (grade 3).This International Standard does not deal with the characterization of the structure-borne sound and liquidbornenoise generated by liquid pumps.NOTE 2 This International Standard is intended to complement EN 809, Pumps and pump units for liquids - Commonsafety requirements.
