Description

ISA 75.07 – Laboratory Measurement of Aerodynamic Noise Generated by Control Valves : ISA Standard S75.07

Formerly S75.07-1997. Defines equipment, methods, and procedures for the laboratory testing and measurement of airborne sound radiated by a compressible fluid flowing through a control valve and its associated piping, including fixed-flow restrictions. The test may be conducted under any conditions agreed upon by the user and the manufacturer. Although this standard is designed for measurement of noise radiated from the piping downstream of the valve, other test variations are optional, including the use of insulation and nonstandard piping. Applications of this standard to control valves discharging directly to the atmosphere are excluded.
