Scope and field of application
This standard includes
-standard methods for testing the regulatingcharacteristics of hydraulic flow control valves;
-a uniform method for presenting the test data;
– standardized information to enable the conducting ofcomparative tests.
This standard is intended to provide a uniform laboratoryprocedure for measuring and reporting the regulatingcharacteristics for a hydraulic flow control valve.
This standard is intended to include steady state performancecharacteristics only. Transient performance tests are notincluded.
