Lower flammability limit (LFL): The lowest concentration (percentage) of a gas or a vapor in air capable of producing a flash of fire in the presence of an ignition source (arc, flame, heat). The term is considered by many safety professionals to be the same as the lower explosive level (LEL). At a concentration in air lower than the LFL, gas mixtures are "too lean" to burn. Methane gas has an LFL of 4.4%. If the atmosphere has less than 4.4% methane, an explosion cannot o… WebConcurrent-flow flammability curve for acrylic cylinders (PMMA); and opposed and concurrent burning behavior of actual engineering materials (sheets) Narrow Channel Apparatus (NCA) Miller: San Diego State University Opposed-flow flame spread data for a thick acrylic (PMMA) slab
