标准范围

ISO 20361:2007规定了在标准化条件下有效地确定、声明和验证液体泵或泵装置的空气噪声排放所需的所有信息。它规定了噪声测量方法以及试验所用的操作和安装条件。ISO 20361:2007的使用确保了在所用基本空气噪声测量方法的精度等级确定的规定限值内，空气噪声发射特性测定的再现性。根据ISO 20361:2006，噪声测量方法为工程方法（2级）和测量方法（3级）。ISO 20361:2007未涉及液体泵产生的结构传播声音和液体传播噪音的特征。

ISO 20361:2007 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. It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test.The use of ISO 20361:2007 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 ISO 20361:2006 are engineering methods (grade 2) and survey methods (grade 3).ISO 20361:2007 does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps.
