The temperature at which the vapour above a volatile liquid forms a combustible mixture with air. At the flash point the application of a naked flame gives a momentary flash rather than sustained combustion, for which the temperature is too low.

Chemical Engineering
The lowest temperature at which a volatile liquid will produce a sufficient amount of vapour to ignite in air at a given pressure. The rapid combustion occurs in the form of a momentary flash. Flash point data is important for the safe storage and transportation of volatile liquids. Compareautoignition temperature.
