Adjusted Set Pressure
Inlet static pressure at which a pressure-relief valve is adjusted to open on the test stand. See set pressure (3.19). NOTE 1 Adjusted set pressure is equivalent to set pressure for direct-mounted end-of-line installations. NOTE 2 The adjusted set pressure includes corrections for service conditions of superimposed back-pressure.
