Cone Calorimeter

Heat release quantity is the core parameter to evaluate the fire behavior of materials and products. LISUN’s 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 Part15).

Cone Calorimeter includes these systems such as heat release, mass loss, smoke generation, etc and allow users to buy the parts they need one by one and add into the same chamber. This flexible feature is one of its advantages.

Cone Calorimeter test theory is based on the principle that the burn calories is proportional to the amount of oxygen’s consumption,1KG oxygen consumption will produce 13.1 MJ heat. All parameters such as gas heat emission, ignition timing, oxygen consumption rate, CO/CO2 generation rate, gas flow can be measured. 

The calorimeter data acquisition system can help users easily control the entire test process. The 19” touch screen can realize automated testing and reduce installation space. In addition, users can also change the sample temperature or adjust the temperature rise time to test after setting up the virtual temperature at real fire conditions. This method can obtain the similar test results to real fire environment.
