Within this review, experimental samples of gypsum wallboard had been subjected to numerous warmth fluxes at different durations using the ASTM E1354, Cone Calorimeter radiant heater. Schroeder was equipped For instance that a crystalline improve would happen in the gypsum wallboard when heated by using an x-ray diffraction strategy. His conclusions show that gypsum wallboard was the one material that can be reliably useful for predicting intensity and length applications. Nevertheless, Schroeder’s review didn't produce a good usually means for implementing this method into a scene inspection.
