(NFPA) - NFPA T3.5.24
Hydraulic fluid power – Pressure relief valves – Method of testing and presenting basic performance data
|Publication Date:||26 August 2001|
This standard includes:
⎯ standard methods for testing the performance characteristics of hydraulic pressure relief valves;
⎯ a uniform method for presenting the test data;
⎯ standardized information for conducting comparative tests.
This standard is intended to provide a uniform laboratory procedure for measuring and reporting the cracking pressure, reseat pressure, pressure regulating characteristics, hysteresis, pressure overshoot, stability and leakage of a hydraulic relief valve.
