Combustible dusts, based on tests conducted in the Setchkin Furnace on five representative dusts, are shown to have two distinct layer minimum ignition temperatures, designated MIT non‐flaming and MIT flaming . The MIT non‐flaming is the one usually reported in the literature; the MIT flaming is determined by starting at a much higher temperature and working downwards. MIT flaming can yield a different ranking of dust flammability than MIT non‐flaming . The MIT flaming appears to be more closely correlated to the MIT of dust clouds and to the test prescribed for flammable solids in the US Code of Federal Regulations than the MIT non‐flaming .
