The Layer Ignition Temperature (LIT) test is conducted to determine the lowest temperature at which a hot surface will ignite a powder when settled as a dust layer.

The material is placed onto an isothermally heated hotplate and formed into a 5 mm layer. Once an ignition temperature is observed the hotplate temperature is reduced and tested repeated with fresh material, until the lowest ignition temperature is established (LIT).

The minimum explosive concentration test is conducted to determine the minimum quantity of powder dispersed in air, as a dust cloud that will ignite. Working through a range of decreasing powder concentrations, the powder is dispersed into a 20L explosion vessel (sphere) using, dry compressed air. These suspended dust clouds are then exposed to a large 2 kJ chemical ignition source and any ignition and following explosion is monitored, measured and recorded. The powder concentration is reduced until ignition is not possible and the MEC established.
