This standard specifies a method for determining the pressure loss and fluid flow rate through valves in piping
systems using water as a test fluid. This method is suitable:
- for valves with low values but higher than 0,1 by determining pressure loss, with respect to fluid flow rate
and density;
- and to valves with equal inlet and outlet nominal sizes.
Industrial-process control valves are out of the scope.
NOTE 1 If using air as a test fluid, other standards e. g. EN 60534-2-3 and ISO 6358 should be referred to.
NOTE 2 For valves with flow resistance coeficient values lower than 0,1, the pressure loss through the valve is very low with
respect to the pressure loss in the test tubes, and values cannot be determined with an acceptable measurement accuracy.
