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.

However, Figure 15 shows that by nature of the varying LTHR magnitude and spark timings, nearly identical end-gas autoignition temperatures were achieved.
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.
Potential hazards associated with fuel, including flammability, detonation limits, and autoignition temperatures must be considered inside and around the engine in case of unintentional fuel leakage.
Paper and wood burned easily because of their low autoignition temperatures. Based on the flash point, the white spirit is considered a flammable liquid (< 37.8[degrees]C); the kerosene and the PGEE are considered combustible liquids ([greater than or equal to] 37.8[degrees]C).
ASTM standard tests exist to measure the minimum explosible concentration, the minimum ignition energy (high voltage spark), minimum autoignition temperatures, maximum pressure generated and the maximum rate of pressure rise (which is a measure of the destructive force).
