Dual Cone Calorimeter


All modern heat release measurements use oxygen depletion calorimetry.The analysis and instrumentation used for quantitative oxygen, carbon monoxide and carbon dioxide measurements in both large- and small-scale calorimetry have the same specification. Thus a single set of instrumentation can be used for other tests. FTT’s Dual Cone Calorimeter houses the common gas analysis instrumentation, higher capacity pumps and gas handling filtration required for Large Scale Calorimeters (e.g. ISO 9705, Furniture Calorimeters, Cable Propagation Rigs, SBI Apparatus) in a separate rack from the main Cone Calorimeter housing.The instrumentation can then conveniently be used both for Cone and Large Scale Calorimeters.


When used with the Cone Calorimeter, the analysis rack is elegantly located with the Cone Calorimeter unit.When instrumentation is required for the Large Scale Calorimeter this section is quickly de-coupled from the Cone frame and transferred, on the factory-fitted castors, to the new location for equally quick connection to power and sampling lines of the larger calorimeter.


The FTT Dual Cone Calorimeter has all the advantages of the conventional single purpose Cone Calorimeter and similarly meets all National and International Standards including:


 ISO 5660-1 Rate of heat release from building products (Cone Calorimeter method).  ISO 5660-2 Smoke production rate (dynamic measurement).





ASTM E 1354 Heat and visible smoke release for materials and products using oxygen consumption calorimeter.





ASTM E 1474 Determination of the heat release rate of upholstered furniture and mattress components or composites using a bench scale oxygen consumption calorimeter.
