Madrzykowski and Fleischmann (2012) performed a analyze of your response of gypsum wallboard as well as reproducibility of the hurt sample created when exposed to known heat release price (HRR) fires with various varieties of fuel sources and wall building. The fuels made use of for their experiments involved a organic gas burner, gasoline pool fire and polyurethane foam.
