Which NFPA standard was developed for testing and maintenance of water-based fire protection systems?

• A. NFPA 25
• B. NFPA 13
• C. NFPA 72
• D. NFPA 101

Answer: (A)

Testing and maintaining water-based fire protection systems requires a standard that directs ongoing care, inspections, and servicing to ensure reliable operation. NFPA 25 is that standard; it specifies the procedures, frequencies, and acceptance criteria for inspecting, testing, and maintaining water-based systems, including components like sprinklers, valves, backflow preventers, and related devices. This guidance helps ensure the systems perform as designed when called upon.

NFPA 13, by contrast, focuses on the design and installation of water-based sprinkler systems, not their ongoing testing and maintenance. NFPA 72 covers fire alarm and signaling systems, not water-based suppression systems, and NFPA 101 addresses life safety requirements across occupancies, not the maintenance of sprinkler systems.
