Industrial-process control valves - Part 8-2: Noise considerations - Laboratory measurement of noise generated by hydrodynamic flow through control valves
Industrial-process control valves - Part 8-2: Noise considerations - Laboratory measurement of noise generated by hydrodynamic flow through control valves.
IEC 60534-8-2:2011 includes the method for measuring the sound pressure level due to liquid flow through a control valve and the method for determining the characteristic increase of noise due to the onset of cavitation.
It also defines the equipment, methods, and procedures for the laboratory measurement of the airborne sound needed to determine these characteristics.
Two methods are provided for testing the noise generating characteristics of control valves:
This second edition cancels and replaces the first edition published in 1991 and constitutes a technical revision that includes internal noise measurement.
