Cone Calorimeter

ZONSKY ASTM E1354 Cone Calorimeter is a specialized testing device used to measure the heat release rate, ignition time, and other combustion characteristics of materials under controlled conditions. In this test, a sample is exposed to a radiant heat source in a conical-shaped chamber, allowing for the evaluation of how materials behave when subjected to fire.Talk To Our Team
