Auto Ignition Temperature
The auto-ignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion.
The auto ignition temperature is determined in a laboratory under specific test conditions, outlined in ASTM E659 – 15 Standard Test Method for Autoignition Temperature of Chemicals.
The Auto Ignition Temperature is a standard property in the substance database of Hazcalc.
