Commonly, investigators think about the facial area of your wallboard and make a visual resolve on the DOFD. The visible overall look of wallboard is utilized in all fire pattern research offered, While only some scientific tests exist that target the baseline features with the various degree of heating and resulting DOFD (Madrzykowski and Fleischmann 2012; Hicks et al.
