For fire protection piping kept above 200 psi, the test pressure must be 50 psi over the maintained pressure. When any system has a fire department pumper connection, it must be hydrostatically tested … main drain connection or other low-point drain connection and allow the system to Perform hydrostatic testing on FDCs and more with ease! The content on this website in no way eliminates the need for assessment and advice from a life safety professional, the services of which should be employed in all situations. NFPA 25 is unclear about what constitutes an acceptable drop in pressure, noting “Minimum leakage existing only under test pressure is not cause for repair.” That said, the separate NFPA 13 guidance on hydrostatically testing underground pipes in fire sprinkler systems may provide some insight: 10.10.2.2.1* All piping and attached appurtenances subjected to system working pressure shall be hydrostatically tested at gauge pressure of 200 psi (13.8 bar) or 50 psi (3.4 bar) in excess of the system working pressure, whichever is greater, and shall maintain that pressure at gauge pressure of ±5 psi (0.34 bar) for 2 hours. pressure at this time. visit and details of your transaction activity, such as the amount, date and time for each 25.2.1.2 Portions of systems normally subjected to system working pressures in excess of 150 psi (10.3 bar) shall be tested as described in 25.2.1.1, at a pressure of 50 psi (3.4 bar) in excess of system working pressure. Standpipes are an essential apparatus in the event of a fire, basically serving as fire hydrants for the interior of a building. For C-900 PVC pipe (Class 150), the test pressure shall be 225 psi and the test duration shall be four (4) hours. The National Fire Protection Association (NFPA) defines a hydrostatic test as “a test of a closed piping system and its attached appurtenances consisting of subjecting the piping to an increased internal pressure for a specified duration to verify system integrity and system leakage rates.
