When pressure systems exceed safe operating limits, safety relief valves provide the last line of defense against equipment damage, regulatory violations, and potentially catastrophic failures. When system pressures exceed safe limits, these devices must respond immediately and accurately to protect personnel, equipment, and operations.
Because of their critical role, regular testing and inspection of safety relief valves are required under ASME, NBIC, and other applicable codes. However, many facilities are uncertain about testing intervals, certification requirements, and the differences between field and bench testing.
