Hydraulic fluid power; Test code for the determination of airborne noise levels; Part 2 : Motors
Описание (англ.):
Establishes a test code describing procedures based on ISO 2204 for the determination of the sound power levels of a motor under controlled conditions of installation and operation, suitable for providing a basis for comparing the noise levels of motors in terms of: A-weighted sound power level, octave band sound power levels. Is applicable to all types of hydraulic motors operating under steady-state conditions, irrespective of size.
