Effects of large hydrocarbon pool fires

ASTM E1529 identifies the effects of thermal shock from a post flashover fire. Structural members and assemblies are exposed to fire conditions resulting from large, free-burning fluid-hydrocarbon- fuelled pool fires. This is intended to simulate complete engulfment by a flame. The test environment reaches a temperature of over 815°C after the first 3 minutes of the test and then remains between 1010°C and 1176°C. Fire resistance ratings are given for the time period during which the structure withstands the fire scenario without allowing the passage of flame or hot gases capable of igniting cotton waste.
