DL06 said:Tom, we deal with LEL/UEL issues here at our plant. Note that LEL refers to a concentration, not a temperature. LEL is the minimum concentration of a substance in air that can catch on fire. UEL (upper explosive limit) is the maximum concentration of a substance in air that will catch on fire.
Under LEL = too lean
Over UEL = too rich
Between LEL and UEL = *woof
Maybe you are referring to the flash point? I'm not sure what it is for gasoline.
Right you are - sorry about that!
