Use and benefit of a controlled-atmosphere cone calorimeter

  • A controlled-atmosphere cone calorimeter that is built by modifying the Standard apparatus with the addition of a controlled-atmosphere chamber offers a time- and cost-saving approach for reaction-to-fire testing in vitiation- and ventilation-controlled atmospheres. Due to the design of the added enclosure no mechanical changes on cone calorimeter’s Standard ductwork are required. This offers some advantages but also important limitations. The design has an open connection between the outlet of the added enclosure and the cone calorimeter’s exhaust hood. Therefore, sufficient ambient air from the laboratory surroundings is drawn into the System to introduce effects which have the potential to affect test results significantly. A procedure which is is suitable to consider physical effects of the ambient air on the calculation of the heat release rate is presented as well as initial results of an application towards toxic potency assessment.
