What is the minimum interval for conducting hydrostatic and flow tests on a standpipe system?

The minimum interval for conducting hydrostatic and flow tests on a standpipe system is at least once in five years. This requirement is established to ensure that the standpipe system maintains its functionality and reliability in the event of a fire emergency. The five-year interval allows for a comprehensive assessment of the system's integrity, including the ability to withstand pressure and the hydraulic performance of the pipes and components. Regular testing is crucial for identifying any potential leaks, blockages, or degradation of materials that could compromise the system's effectiveness when it is most needed, thereby enhancing overall life safety in the building.
