The '''flash point''' of a material is the "lowest liquid temperature at which, under certain standardized conditions, a liquid gives off vapours in a quantity such as to be capable of forming an ignitable vapour/air mixture".<ref>{{cite web | url=https://webstore.iec.ch/en/publication/63327 | title=Iec 60079-10-1:2020 }}</ref>

The flash point is sometimes confused with the [[autoignition temperature]], the temperature that causes [[spontaneous ignition]]. The [[fire point]] is the lowest temperature at which the vapors keep burning after the ignition source is removed. It is higher than the flash point, because at the flash point vapor may not be produced fast enough to sustain combustion.<ref>Sea Transport of Petroleum, Jansen and Hayes, Ainsley, South Shields 1938</ref> Neither flash point nor fire point depends directly on the ignition source temperature, but ignition source temperature is far higher than either the flash or fire point, and can increase the temperature of fuel above the usual ambient temperature to facilitate ignition.
