Hydraulic fluid power. Valves. Determination of differential pressure/flow rate characteristics1 Scope This document specifies methods for determining, under steady state conditions, the pressure differential caused by the flow through any given path in a hydraulic fluid power valve. Requirements for test installations, procedures and presentation of results are specified.

This standard specifies the requirements
