Based on McGrattan et al. (2026), pp. 77–79, and Van Rossum (2027), §5.2 and §5.4.<br /> <br /> Original illustration for [[Adiabatic surface temperature]], level 4 Expert.<br /> <br /> * Source basis: McGrattan et al. (2026), pp. 77–79 (heat balance terms); Van Rossum (2027), §5.2 (hc 20–25 W/(m²·K) for a fully developed fire, usually 25 for a standard fire; used here as an assumption), §5.4 (σ, emissivity 0.9 for paint), §4.7 (20 kW/m² from a 500 °C smoke layer); Gann, Hamins, et al. (2005), p. 84 (h = 25 W/(m²·K))<br /> * Alt text: Line chart: adiabatic surface temperature rises with incident radiation; at 20 kW/m² it is 377 °C in air at 20 °C and 498 °C in gas at 500 °C.<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
