What is the primary difference in scope between NFPA 13 and NFPA 25?

• A. NFPA 13 covers design, installation, and modification of sprinkler systems; NFPA 25 covers inspection, testing, and maintenance.
• B. NFPA 13 covers maintenance; NFPA 25 covers design.
• C. NFPA 13 covers sprinkler materials; NFPA 25 covers building code.
• D. NFPA 13 covers alarm integration; NFPA 25 covers code enforcement.

Answer: (A)

NFPA 13 defines what it takes to design, install, and modify a fire sprinkler system, laying out the technical requirements for how a system should be put together in a new or changed building. NFPA 25, on the other hand, governs what happens after a system is in place: it covers inspection, testing, and maintenance of existing sprinkler systems to keep them functioning properly over time. So the key difference is design and installation versus ongoing care and verification. The other options mix in maintenance or codes or alarm aspects that aren’t the primary focus of these standards.
