During testing and inspection, identify the standard used for foam-water sprinkler systems?

• A. NFPA 13
• B. NFPA 70
• C. NFPA 25
• D. NFPA 20

Answer: (C)

NFPA 25 is the standard used for testing and inspection of foam-water sprinkler systems. It specifically covers the inspection, testing, and maintenance of water-based fire protection systems, including those that use foam concentrate. This standard lays out what needs to be tested, how often, acceptable performance criteria, and documentation requirements to ensure the system remains ready to perform. While NFPA 16 governs the installation of foam-water sprinkler systems and NFPA 13 covers general sprinkler system design and installation, the ongoing testing and inspection work falls under NFPA 25. NFPA 70 is about electrical installations and NFPA 20 covers fire pumps, which are not the focus of testing and inspection for the foam-water portion.
