Ignition Energy for liquid and gases has three measurements, flash point, fire point and auto-ignition temperature.
Flash Point: When vapours and gases reach their flash point they are capable of being ignited momentarily by an outside source of heat(spark, etc.) but will then go out as there is insufficient gas or vapour being evolved to continue burning. The flash point of a substance or preparation is an indication of its flammability. The lower the flash point, the greater the hazard.
Fire Point: When vapours and gases reach their fire point sufficient gas/vapour is being given off to sustain a flame when ignited by an outside source of heat (Spark, etc.)
Auto Ignition Temperature: Vapours and gases that are heated even further will reach their auto-ignition of self-ignition temperature, when they will ignite without any external source of ignition.
Flammable: Liquids with a flash point between 320°C and 550°C are classified as flammable.
Highly Flammable: Liquids with flash point below 320°C are classified as highly flammable.
