This test is designed to determine the ignition temperature of airborne dust on a hot surface (e.g. spray drier).

First the oven is heated up to 600°C. With the heater switched off and the oven temperature falling, the dust samples are blown into the oven by means of a rubber bulb, e.g. every 50°C.

Ignition is considered to have taken place, if the injected dust ignites or decomposes producing flames and/or explosion.
