2020-02-25 /Definitive
IEC 60534-2-3:2015(E) 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.
