Which identifies heat sources for sprinkler temperature ratings?

• A. Table 6.2.3.3.3
• B. NFPA 13
• C. Deflector location
• D. Coverage criteria

Answer: (A)

Heat ratings for sprinklers come from standardized test conditions, so you need the reference that lists those test heat sources. In NFPA 13R, Table 6.2.3.3.3 specifies the heat-source scenarios used to determine a sprinkler’s temperature rating. This tells you exactly which ambient or heat conditions were considered when the rating was established, so you can choose a sprinkler that will activate at the right temperature in your environment. The rest of NFPA 13R covers the overall design and installation details like deflector location and coverage criteria, but those parts don’t identify the heat sources used for rating.
