Fire tests - Reaction to fire - Part 1: Rate of heat release from building products - (Cone calorimeter method)
The rate of heat release is determined by measuring the oxygen consumption derived from the oxygen concentration and the flow rate in the combustion product stream. The time to ignition (sustained flaming) is also measured. Products with surface irregularities may be tested according to specific requirements.
