During testing, which standard applies to foam-water sprinkler systems?

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

Answer: (C)

Testing foam-water sprinkler systems is governed by the standard that covers inspection, testing, and maintenance of water-based fire protection systems. Foam-water systems fall under this category, so the procedures, test requirements, and maintenance intervals come from that standard. The foam-water installation standard handles design and installation aspects, but the actual testing activities—such as verifying system operation, conducting hydrostatic tests, and checking foam proportioning—are specified in the testing and maintenance standard. The other standards serve different roles: one is focused on general sprinkler system installation, another on electrical installations, and another on fire pump equipment.
