Air Over Layer
The air over layer test is conducted to establish the onset temperature of exothermic activity of thin layers of material when exposed to elevated atmospheric temperatures.
For further details see links to dedicated test pages on highlighted tests.
Bulk Powder (diffusion cell)
The bulk powder diffusion cell test is conducted to establish the onset temperature of exothermic activity of a material when exposed to elevated atmospheric temperatures.
Aerated Cell
The aerated bulk powder diffusion cell test is conducted to establish the onset temperature of exothermic activity of a material when exposed to elevated atmospheric temperatures.

Auto-Ignition Temperature
The auto-ignition temperature (AIT) test is conducted to determine the lowest temperature at which a substance will produce hot-flame ignition in air at atmospheric pressure, without the aid of an external energy source such as spark or flame.
Flammable Limits (LEL / UEL)
This test is conducted to determine the lower and upper concentration limits of flammability of chemicals having sufficient vapour pressure to form flammable mixtures in air at atmospheric pressure at a specific test temperature.
