WebApr 28, 2012 · The two most important properties of flammable gases are the upper flammability limit (UFL) and the lower flammability limit (LFL). These are frequently called the upper and lower explosion limits (UEL and LEL). The LFL is the concentration of fuel vapor in air below which combustion is not possible; the mixture is considered too lean.
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].
