The Cone Calorimeter has long been considered the most significant bench scale instrument in the field of fire testing. This was substantiated in 2016 by the $50,000 DiNenno Prize, which recognized oxygen consumption calorimetry as a significant technical achievement that has had a major impact on public safety. The 2016 Philip J. DiNenno Prize was awarded to Dr. William Parker, who conducted his research on the cone calorimeter at the U.S. National Bureau of Standards. The DiNenno Prize directed ample commendation to his deceased NIST collaborator, Dr. Clayton Huggett. Others who made contributions to the early development and application of oxygen consumption calorimetry include Peter Hinkley, William Christian, Thomas Waterman, Darryl Sensenig, Ralph Krause, Richard Gann, Vyto Babrauskas, Gunnar Heskestad, Norm Alvares, Donald Beason, and Brady Williamson. Fire Testing Technology Limited (FTT) in the UK is currently the largest manufacturer of Cone Calorimeters.
