Description
For Fire Testing and Fire Safety Engineering in Accordance with ISO 5660-1
The cone calorimeter is considered the most significant instrument in fire testing. This is because the net heat of combustion is propor tional to the amount of oxygen required for combustion. The specimens are irradiated, ignited by sparks and thereby combusted. This apparatus analyzes the combustion gases and measures the smoke produced from a test specimen that is being exposed to a certain heat flux. The principle is known as the “oxygen consumption principle” and is among the methods of calorimetry. From the oxygen concentration, the released heat is calculated. In addition, precision can be improved by analyzing carbon monoxide and carbon dioxide concentrations.
