Assessing materials reaction-to-fire
Reaction-to-fire testing analyzes how a material or product responds to a controlled fire challenge. Measurements can include how fast the material ignites, how much and how quickly heat is emitted, how much mass is lost, and how much smoke is produced.
The rate of heat release is considered to be the most significant predictor of a potential fire hazard, and the cone calorimeter is the most valuable bench-scale instrument in fire testing to quantitatively evaluate the relative risk that different materials pose.
Cone calorimeter applications
Due to the relatively small specimen sizes used for the test, the cone calorimeter test is a cost-effective way to research the fire performance of products while still in the developmental stage, for assessing material compliance to established performance requirements, as on-going quality control, or even to generate data for litigation purposes.
Additional advantages to cone calorimeter testing are the ability to determine non-combustibility of materials and their critical heat flux, which can play an important role in material selection for critical applications.
