Building Material Heat Release Rate Flammability Testing Machine /
Cone Calorimeter
Application:
Combustion product stream through the oxygen concentration of the
oxygen consumption and calculate the heat release rate, heat
release rate of the material is also the material properties of the
combustion products of the combustion burner of the most important
parameters, more accurately measure the material during combustion
heat release rate, for predicting fire hazard prevention and
fire-retardant treatment is extremely important.
Standards:
