Reduced scale test bench for investigating the upward flame heat impact on external thermal insulation composite system facades

Abstract

The project aimed to develop a reduced scale test protocol designed to be repeatable and capable of providing the upward fire evaluation for assessing fire risk on external thermal insulation composite system facade samples. The variation of heat flux is simulated by radiant panel. This experimental setup permits the recording of dynamic variables in flame propagation, such as ignition time, flame extinguishing time, and variations in both surface and back temperatures of the insulation panel. Notably, the measurement of back temperature provides a means to assess the thermal insulation efficiency of the external thermal insulation composite system facade. Furthermore, the fire spreading temperature is collected during the test could also be useful for larger-scale testing.
