Which NFPA standard specifies the 175 psi limit at hose connection outlets of standpipes?

Explanation:
Standpipe hose outlet pressures are governed by NFPA 14. This standard covers standpipes and hose systems, including how hose connections are designed and what pressures they may deliver. NFPA 14 specifies that the pressure at a standpipe hose connection must not exceed 175 psi, helping ensure the hose, nozzle, and operator can handle the flow safely and reliably. NFPA 13 deals with sprinkler systems, NFPA 20 with fire pumps, and NFPA 101 with life safety requirements, so they don’t set this standpipe outlet pressure limit.
