Heat release is the core measurement parameter for evaluating the fire characteristics of materials and products.
The cone calorimeter can meet all existing standards, including ISO 5660, ASTM E 1354, ASTM E 1474, ASTM E 1740, ASTM F 1550, ASTM D 6113, NFPA 264, CAN ULC 135, and BS 476 Part 15.

It may also be purchased in component form. Laboratories requiring specific tests such as heat release, mass loss, or smoke generation can first purchase the required modules and later add other instruments into the same test chamber to form a complete system.

The test theory of the cone calorimeter is based on the principle that pure combustion calorific value is proportional to the oxygen consumed in combustion. For every 1 kg of oxygen consumed, 13.1 MJ/kg of heat will be generated.

Heat release of the test gas, ignition time, oxygen consumption rate, CO and CO2 generation rate, and gas airflow are measured. The DAQ system helps the user control the whole test process, while the 19-inch touch screen supports automation and reduces installation space.

After setting the simulated temperature corresponding to real fire conditions, the user can conduct tests by changing specimen temperature and temperature rise time, obtaining results similar to real fire environments.
