Flame Cone Calorimeter Test , Fire Resistance Testing Laboratory Universal Standard ISO5660
Cone Calorimeter measures heat release rate(H.R.R), smoke release, ignition time, oxygen consumption, carbon monoxide and carbon dioxide generation and mass loss rate when specimen is exposed to resource of conical heater.
The name of Cone Calorimeter is derived from the conical heater as used by Dr. Vytenis Babrauskas to inspect test specimen (100mm*10mm) with flux up to 100kW/m2 for the bench scale oxygen depletion of his development.
ISO 5660 Building Materials Cone Calorimeter is based on the theory that pure combustion calories are in proportion to a necessary amount of oxygen for combustion and 13.1 MJ/kg is generated whenever oxygen 1kg is consumed, and heat emission, ignition time, oxygen consumption, CO and CO2 generation, and flow of ignited gases as generated from test materials are measured.
ISO 5660 Building Materials Cone Calorimeter is made for easily controlling the whole parts with DAQ (Data Acquisition) Program in a laboratory. And 19’’ touch screen helps to test automatically as well as reduce installation space.
Additionally, Conical Heater 5 Step Heat Flux Controller (optional part for R&D purpose) helps to measure combustion characteristic about specimen by temperature change and temperature rising time after setting up virtual temperature of real fire conditions. This option helps to measure various results similar to real fire environment. User can set up the user's temperature, rising speed and lasting time after rising with 5 Step Heat Flux Controller and use easily.
