GB/T 4980-2003 《Determination of sound level for noise emitted by displacement compressors》 Related products
This standard specifies the measurement method of the noise of the volumetric compressor, including the measurement method of the sound power level and the sound pressure level of the noise. This standard refers to the documents such as GB/T 3785-1983 Electroacoustic performance and test method of sound level meters to ensure the accuracy and standardization of measurement and reporting.
