Answer: C

Explanation:

The cone calorimeter is an ignition test method that exposes the specimen to a known heat flux from a tungsten-quartz heater. The cone calorimeter measures the heat release rate, mass loss rate, smoke production, and other parameters of the specimen during the test. The cone calorimeter is widely used to evaluate the flammability and fire behavior of materials and products.
