Dust Combustibility (Group A/B)

The test is conducted to assess whether a dust/powder will form a flammable atmosphere, supporting flame propagation, when dispersed as a dust cloud in air.

Minimum Ignition Energy (MIE)

The minimum ignition energy (MIE) test is conducted to determine the lowest spark energy that will ignite a powder when dispersed in air, as a dust cloud.

Minimum Ignition Temperature (MIT)

The Minimum Ignition Temperature (MIT) test is conducted to determine the lowest temperature at which a hot surface will ignite a powder when dispersed in air, as a dust cloud.

Layer Ignition Temperature (LIT)

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.

Explosion Severity (Pmax, Kst)

The explosion severity test is conducted to determine maximum pressure (Pmax), Maximum rate of pressure rise ((dP/dt)max) and Kst of an ignited powder, dispersed in air, as a dust cloud.

Limited Oxygen Concentration (LOC)

The limiting oxygen concentration test is conducted to determine the minimum quantity of oxygen, within an atmosphere, that will enable a powder dispersed in air, as a dust cloud to ignite.

Burning Behaviour

The test is conducted to assess the behaviour (severity) of combustion propagation through a material deposit on being ignited by an external ignition source.
