WebThe purpose of the Limiting Oxygen Index (LOI) test, sometimes referred to as Oxygen Index (OI) or Critical Oxygen index (COI), is to measure the relative flammability of plastics and composite materials by burning them in a controlled atmosphere consisting of a mixture of oxygen and nitrogen.
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].
