scope:
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 Zeta 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.
