Industrial-process control valves - Part 2-3: Flow capacity - Test procedures
IEC 60534-2-3:2015 is applicable to industrial-process control valves and provides the flow capacity test procedures for determining the following variables used in the equations given in IEC 60534-2-1:a) flow coefficient C;b) liquid pressure recovery factor without attached fittings FL;c) combined liquid pressure recovery factor and piping geometry factor of a control valve with attached fittings FLP;d) piping geometry factor FP;e) pressure differential ratio factors xT and xTP;f) valve style modifier Fd;g) Reynolds number factor FR.This third edition cancels and replaces the second edition published in 1997, of which it constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:a) Addition of informative Annexes B, C, D, E and F.b) Organizational and formatting changes were made to group technically related subject matter.
