Which NFPA standard requires that circulating closed-loop sprinkler systems be inspected, tested, and maintained?

Explanation:
NFPA 25 covers the ongoing care of water-based fire protection systems, including circulating closed-loop (antifreeze) sprinkler systems, through inspection, testing, and maintenance. This standard provides the schedules, procedures, and documentation needed to verify that these systems remain reliable, control corrosion, check antifreeze concentration, inspect for leaks, test valves and backflow devices, and ensure alarms and drains function properly. The goal is to keep the system ready to operate as designed. The other standards focus on different aspects: NFPA 13 addresses design and installation of sprinkler systems, NFPA 14 covers standpipe systems, and NFPA 20 relates to pump installations.
