ISO 5660 Cone Calorimeter
Application
The oxygen consumption calculated from the oxygen concentration in
the combustion product gas stream and the heat release rate of the
combustion products when burning, the material's heat release rate
is also the most important parameter in the material combustion
performance, and the heat release rate in the material combustion
process is measured accurately. For the prediction of fire hazards
and its fire-retardant treatment is extremely important.

What is a cone calorimeter test?
A cone calorimeter is a device 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 Calorimeter has long been considered the most significant
bench scale instrument in the field of fire testing.
