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.
