Fire growth curve
WebFeb 6, 2024 · For each building space, fire curves can be designed that indicate the temperature dependency over time. Such curves are a useful tool for designing fire safety in buildings. During testing, the building elements are exposed to a heat load, which is determined by the standard fire curve. WebMar 1, 1997 · The development of a fire from a point ignition to some equilibrium state and the associated increase in fire size and intensity has been referred to variously as the fire growth (Pyne...
