Cone Calorimeter

ISO 5660, BS476 PART 15, ASTM E 1354, ASTM E 1550, ASTM E 1740, ASTM D 5485, ASTM D 6113, NFPA 271, NFPA 264, CAN ULC 135

The Concept Cone Calorimeter is used for assessing the rate of heat release and smoke production of polymeric and other types of materials. The specimens are generally exposed in the horizontal orientation to controlled levels of irradiance with an ignition probe positioned just above the exposed sample surface. The heat release rate is determined by measurement of the oxygen consumption derived from the oxygen concentration and the flow rate in the combustion product stream. The time to ignition (sustained flaming) is also measured in this test.

The dynamic smoke production rate is calculated from measurement of the attenuation of a laser light beam by the combustion product stream. Smoke obscuration is recorded for the entire test, regardless of whether the specimen is flaming or not.
