Products:
Heat release is the core parameters to assess the fire behavior of materials and products; TESTech's Cone calorimeter to meet all existing standards (including ISO 5660, ASTM E 1354, NFPA 264,
CAN ULC 135 and BS 476 Part 15), And it include the system such as heat release, mass loss, smoke generation, etc.
This flexible feature is the cone calorimeter many advantages in one.
Cone Calorimeter test theory is based on the principle that the burn calories is proportional to amount of oxygen's consumption. 1KG burned oxygen will produce 13.1 MJ/kg of gas heat release. Test gas heat emission, ignition timing, oxygen consumption rate, CO/CO2 generation rate, the gas flow will be measured all. Cone Calorimeter DAQ system can help users to easily control the entire test. 19 "touch screen can help realize the automate testing and reducing installation space. In addition, after users setting up the virtual temperature real fire conditions, who could also change the sample temperature, the temperature rise time to test. This method is similar to obtain real fire environment the test results.
