标准范围
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 liquidpumps 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,- purpose of noise control at source at the design stage.The use of this International Standard ensures the reproducibility of the determination of the airborne noiseemission characteristics within specified limits determined by the grade of accuracy of the basic airborne noisemeasurement 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 liquidborne noise generated by liquid pumps.
