Drip ignition point

The drip ignition point is a measured variable in the natural sciences and describes the temperature at which a liquid substance ignites by itself when dripped onto a hot surface. It is usually much lower than the gas ignition point (the temperature that is decisive for the spontaneous ignition of gases and vapors) of the compounds.

The dropping ignition point should not be confused with the dropping point , which only affects the meltability of solid substances such as bitumen , fats, pitch , lubricants, petroleum jelly , etc.
