A cone calorimeter is a fire test tool that is based on the amount
of heat released during the combustion process directly related to
the oxygen consumption in the combustion process. The amount of
heat generated is directly proportional to the severity of the
fire, such as the rate of fire growth. In order to obtain the
flammability of the material, this is exposed to an external
radiation heat source. Therefore, since this is a forced combustion
test, the cone value is generally considered to reflect the second
ignitability of the ignition.
1). Displays the instrument status.
