Introduction
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. It is a purely qualitative test and categorises a material into one of two groups:
Combustible (Group A) – Flammable or Explosible as a dust cloud
Non-Combustible (Group B) – Non-Flammable or Explosible as a dust cloud
Varying concentrations of dust are dispersed in either a 1 litre glass modified Hartman tube and subjected to a constant arc ignition source. Visually, observing for flame propagation away from the ignition source. Or the test is conducted, dispersing the dust into a 20L explosion vessel and exposed to a 2 kJ ignition source, monitoring for a pressure rise using sensitive, piezo resistive transducers.
