Experimental study of upward and lateral flame spread on MDF boards in corner configurations

This study focuses on flame spread in corner configurations on Medium Density Fiber (MDF) boards. A set of results is discussed from an experimental campaign conducted in the form of standard Single Burning Item (SBI) tests. The repeatability of the tests, the backside boundary condition, and the thermal attack symmetry are discussed. Temperature distributions over the boards through their thickness and at their backside are presented to provide the evolution of panel temperatures. Heat fluxes are measured at certain characteristic locations during the tests, and temporal profiles of the total heat release rate and the smoke production rate are determined based on the oxygen depletion technique by extracting the combustion gases. The visual observations of flame spread are recorded via video cameras from two different angles.This study focuses on flame spread in corner configurations on Medium Density Fiber (MDF) boards.
