lecone calorimeterwas developed by V. Babrauskas and others of NIST in the United States in 1980s. After more than 30-years development,the cone calorimeter has became one of most important instrument used to study the fire behavior of small samples of various materials in condensed phase.It is widely used in the field of Fire Safety Engineering.
The cone is based on oxygen comsumption principle during material combustion. The amount of heat a material generates is directly aligned with the severity of a fire, such as fire growth rate.
In order to access the material flammability, it is exposed to an external radiant heat source. Therefore, since this is a forced combustion test, the cone values are most often thought to reflect flammability of a second item ignited.
