IEC 60534-8-3 Ed. 2.0 b:2000, Industrial-process control valves - Part 8-3: Noise considerations - Control valve aerodynamic noise prediction method

Establishes a theoretical method to predict the external sound-pressure level generated in a control valve by the flow of compressible fluids. Applies to the following single-stage valves: globe (single and double seated), butterfly, angle, rotary plug (eccentric, spherical), ball, and valves with cage trims.
