autoignition temperature

The minimum temperature needed for self-sustained combustion in absence of a spark or flame, at which the vapours from a volatile liquid will ignite spontaneously.

The autoignition temperature (AT) is of interest to the Occupational Safety and Health Administration (OSHA) (US), which lists ATs in its Materials Safety Data Sheets, see there.

Autoignition of the unburned end gas in gas engines is initiated by rapid (exothermic) oxidation reactions, leading to heat release that exponentially increases the temperature, causing the overall reaction to auto-accelerate.

Cooking with solid fuel, like wood, produces creosote and deposits this highly combustible material in exhaust hoods and ducts, where its low flash point and autoignition temperatures can create a fire hazard.
