Which standard is widely referenced as the basis for the installation of sprinkler systems in buildings?

• A. NFPA 13R
• B. NFPA 13
• C. Water meters
• D. Color identification

Answer: (B)

NFPA 13 provides the overall framework for designing and installing sprinkler systems in a wide range of buildings. It covers how systems are sized, where sprinklers and piping go, how hydraulics are calculated, what water supply is needed, and how systems are tested and maintained. NFPA 13R exists for low-rise residential occupancies (typically up to 3 stories) with simplified requirements to reduce cost, so it isn’t the general basis used for all installations. Water meters are for measuring water usage, and color identification deals with markings rather than the installation criteria for sprinklers. Because the broad, widely referenced foundation for sprinkler installations across most building types is NFPA 13, that standard is the best answer.
