The Cone Calorimeter is the most significant bench scale instrument in the field of fire testing.

Heat release is the key measurement required to assess the fire development of materials and products. Traditionally it has been very difficult to measure and more recently full scale testing of items (e.g. furniture) has been possible by burning these articles and measuring the evolved heat using a technique called oxygen depletion calorimetry.

In the early 1980's workers at NIST (formerly NBS), in the USA, decided to produce an improved bench scale heat release test which would overcome the deficiencies of existing small scale heat release tests which relied on the measurement of the outflow enthalpy of enclosed systems. Oxygen depletion calorimetry was identified as the best measurement method. This 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. The instrument was called a Cone Calorimeter. This name was derived from the shape of the truncated conical heater that is used to irradiate the test specimen with fluxes up to 100 kW/m² in the test.

The FTT Cone Calorimeter has been produced to meet all existing Standards (including ISO 5660, ASTM E1354, ASTM E1474, ASTM E1740, ASTM F1550, ASTM D6113, CAN ULC 135 and BS 476 Part 15) and can also be purchased in modular form so that those laboratories with particular interests such as heat release, mass loss, smoke production, etc. can initially purchase the sections they require and later add further instrumentation into the same cabinets in order to complete a full specification instrument. This is just one of the advantages of the FTT Cone Calorimeter.
