Whether you store, handle or process combustible materials, it is necessary to have all applicable data needed to assess risk at ambient, atmospheric and process conditions. The flammability properties of gas or vapor atmospheres are often affected by operating and processing conditions such as chemical properties, temperature, pressure, composition of the fuel gas or vapor mixture, concentration of inert gaseous components, concentration of gaseous oxidants, volume and material of construction of the test vessel. Deatak continues to meet industry demands worldwide as the USA's largest manufacturer of fire and flammability test instrumentation.


The Cone Calorimeter is the most widely used test apparatus to measure heat release properties of materials.
