The first is a uniform method of measuring the radiated noise from the valve and the associated test piping including fixed flow restrictions through which the test fluid water is passing.
The current IEC standard for predicting aerodynamic noise in control valves regulating the flow of gases and vapors is being revised by Working Group 9 of the IEC Subcommittee 65B. The tests described in reference 1 established that the present standard can lead to considerable inaccuracies concerning the predicted sound pressure level. This second edition cancels and replaces the first edition published in and constitutes a technical revision that includes internal noise measurement.
The second is a procedure for measuring the sound pressure levels within pipe systems upstream and downstream of the valve under fixed operating conditions. Please first log in with a verified email before subscribing to alerts.
