Air Over Layer is conducted primarily for the purposes of transportation. Mixtures of a reference oxidiser (potassium bromate) / cellulose (fuel) and mixtures of the substance and cellulose (fuel) to be tested are prepared in specified ratios. Using a conical funnel the mixtures are formed into a truncated conical pile, covering a looped ignition wire resting on the low heat conducting plate.

Flammability of Solids (Burning Rate) test is conducted primarily for the purposes of transportation.

The test is conducted primarily for the purposes of transportation. A powder strip is formed using a triangular cross sectioned mould, onto a heat resistant, non-porous plate. Using a butane flame, one end of the strip is ignited and the initially the time taken to burn over a marked 200 mm length is recorded.
