WebThe upward flammability limiting oxygen indices (ULOIs) were calculated with the “up-and-down method for small samples” [9]. This method has been adopted by both ISO 4589 [10] and ASTM D 2863 for determining the “minimum oxygen concentration required to support combustion of plastics” [8]. Mixtures of dispersed combustible materials (such as gaseous or vaporised fuels, and some dusts) and oxygen in the air will burn only if the fuel concentration lies within well-defined lower and upper bounds determined experimentally, referred to as flammability limits or explosive limits.
