Frederick Schall


Fred has over 40 years of experience in material destructive physical testing. In 1979, Fred focused his interests to specialize in fire and flammability tests. In 1982, he designed and constructed the first commercially produced Cone Calorimeter adherent to ISO 5660-1&2 and ASTM 1354 in the world, introducing Heat Release Calorimetry to industry and research. In 2005, Fred again was the first to make Small Scale Heat Release Calorimetry available to industry and research by manufacturing the Microscale Combustion Calorimeter adherent to ASTM D7309.

Fred holds leadership positions in International, National, Government, and Industry consensus standards and regulatory committees such as American Society for Testing and Materials (ASTM), International Standards Organization (ISO), National Fire Protection Association (NFPA), US Department of Transportation, Federal Aviation Administration (FAA) International Aircraft Materials Fire Test Working Group (IAMFTWG), and Federal Aviation Administration (FAA) International Aircraft System Fire Protection Working Group (IASFPWG).
