- Lower_flammable_limit abstract "Lower flammability limit (LFL), usually expressed in volume per cent, is the lower end of the concentration range over which a flammable mixture of gas or vapour in air can ignite at a given temperature and pressure. The flammability range is delineated by the upper and lower flammability limits. Outside this range of air/vapor mixtures, the mixture will not ignite (unless the temperature and pressure are increased). The LFL decreases with increasing temperature; thus, a mixture that is below its LFL at a given temperature may ignite if heated sufficiently. For liquids, the LFL is typically close to the saturated vapor concentration at the flash point, however, due to differences in the liquid properties, the relationship of LFL to flash point (which is also dependent on the test apparatus) is not fixed and some spread in the data usually exists.The of a mixture can be evaluated using the Le Chatelier mixing rule, if the of the components are known:Where is the lower flammability of the mixture, is the lower flammability of the -th component of the mixture, and is the molar fraction of the -th component of the mixture.".
