Standard:EN ISO 13927; EN ISO 17554
What is the relationship between heat release and mass loss?
The heat of combustion is the quantity of heat released when unit quantity of a fuel is fully oxidised. These are determined using an oxygen bomb calorimeter and are well reported in handbooks. If all fires involved complete oxidation then the heat released could be determined simply by weighing the sample as it burns and multiplying the mass loss by the heat of combustion. In reality, combustion does not usually proceed to complete oxidation but the effective heat of combustion is constant for a given material when burnt at a given heat flux under constant ventilation conditions. Instruments such as the cone calorimeter and the OSU determine the effective heat of combustion.
Heat release is then determined as a product of the effective heat of combustion and the mass loss rate. Once the effective heats of combustion are known for a material over a range of conditions the heat release rates can be calculated from mass loss data. The FTT Mass Loss Cone is designed for this purpose.
