In the hydrostatic test, what is the required duration before building occupancy?

Explanation:
Hydrostatic testing is used to verify that a standpipe or hose system can withstand its test pressure without leaks. The required duration is two hours, during which the system is held at the test pressure to reveal any slow leaks or failures in piping, joints, and fittings. Only after successfully maintaining the pressure for this period and showing no significant loss is occupancy allowed, as prescribed by NFPA 14. Shorter tests could miss leaks, while longer durations aren’t required by the standard and would unnecessarily delay occupancy.
