Ignition point measurement – fire point

Qu’est ce que le ignition point ?

The ignition point is the temperature at which a liquid compound emits enough vapor to form a mixture with air whose combustion is self-sustaining once it has started (flame, spark, etc.). Also called “fire point”, it should not be confused with the point flashpoint or the auto-ignition point. This property makes it possible to characterize the combustibility of a liquid.

How to measure the ignition temperature?

In general, the compound is placed in a reactor under stirring in the presence of a flame. During an increasing temperature ramp, the lowest temperature at which persistent combustion of vapors is observed is the ignition point (for a minimum of 5 seconds).
