GB/T 10069.1-1988 Measurement of airborne noise emitted by rotating electrical machinery and the noise limits--Engineering method for the measurement of airborne noise (English Version)
This standard specifies the engineering test methods for the noise radiated in the air by a single rotating electrical machine in stable operation. The standard deviation of the A-weighted sound power level is not greater than 2dB when the motor noise is measured according to the method specified in this standard. This standard is applicable to the noise measurement of a single motor whose external dimensions are not greater than 15m in the three directions of length, width and height during steady-state operation.
