Flexibility with FTT Calorimeters
FTT calorimeters are designed to have interchangeable modules that give our clients maximum operational or upgrade flexibility.A variety of analysers can be housed within our systems and the major components themselves can also have
multi-use.The small entry level Mass Loss Calorimeters (ISO 13927 and ISO 17554) can be used as a spare calorimeter furnace model, extended to measure smoke in accordance with ISO 5660-2 or developed further to become a full Cone
Calorimeter.The analysis systems of the Dual Cone Calorimeter can be transported to large calorimeters within
minutes.Almost all ducted rigs like the IEC 60332-3 can be readily converted to large calorimeters by use of the rack from a Dual Cone Calorimeter and a duct insert which FTT provide. The latter houses all necessary gas sampling, temperature and mass flow probes.
Furniture calorimeter Used to measure heat release and mass loss from furniture.
IEC 60332-3 cable testing rig Readily converted to enable heat release from cable tray tests to be measured.
Duct Insert Fitted into exhaust ducts of dynamic test
methods.This houses gas temperature and mass flow probes and smoke measuring hardware.
ISO 9705 Room Corner test Used extensively to measure the heat release from wall lining materials.
EN 13823 The SBI test method used extensively in Europe to test construction products.
Principle of measurement
This technique is based on the empirical observation that heat released by burning materials is directly proportional to the quantity of oxygen used in the combustion
process.Most fuels were found to generate 13.1 x 103
kJ/kg of oxygen consumed.
Measurement of the precise concentrations of oxygen in the exhaust duct and the volumetric flow of air gives the rate of oxygen consumption from which the heat release rates can be calculated. In the Cone Calorimeter the rate of heat released is given by:
