Dust Combustability (Group A/B) Sigma-HSE Flammability Test
Flammability test 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. https://sigma-hse.com/dust-and-powder/group-ab-flammability-test

Additional Tests Available at our Environmental Laboratory (ELab) UK.Our environmental laboratory, ELAB, specialises in the testing for contamination in soil, water and leachate samples. https://sigma-hse.com/additional-tests-available/elab
Transportation Classification Testing | OXIDISING SOLIDS | Sigma-HSE
The test 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.
