Which NFPA standard governs the hydrostatic test for foam piping?

• A. NFPA 12
• B. NFPA 11
• C. NFPA 16
• D. NFPA 2001

Answer: (B)

Hydrostatic testing of foam piping is addressed by NFPA 11, which governs foam firefighting systems. This standard covers the design, installation, testing, and maintenance of foam systems, including the procedures to perform hydrostatic tests and prove the piping and components can safely withstand system pressure. The other NFPA standards relate to different extinguishing media—NFPA 12 deals with clean agent systems, NFPA 16 with dry chemical systems, and NFPA 2001 with clean agent (often gaseous) systems—so they don’t govern foam piping hydrostatic testing.
