And Fire Point is the temperature at which if fuel is heated to give off sufficient vapors so it can continue to burn for more than 5 seconds is called 'Fire Point'. Both flash point and auto ignition temperature are related to the ignition of materials at the lowest possible temperature. Neither flash point nor fire point depend directly on the ignition source temperature, but it may be understood that ignition source temperature is considerably higher than either the flash or fire point [33]. 2. Normally 'Fire Point' is more than 'Flash Point' by 10-20 °C. The flash point should not be confused with the auto-ignition temperature, which does not require an ignition source. The key difference between flash point and auto ignition temperature is that flash point determines the lowest temperature at which vapour of a material starts ignition in the presence of an ignition source whereas auto ignition temperature is the lowest temperature at which a material can start ignition spontaneously. To understand the difference between ignition temperature and fire point, we must first understand the definition of the two (2) parameters. AddThis. Although they share similarities, they are very different terms. But, fire point gives the lowest temperature at which the vapour of a substance can keep burning when we remove the ignition source, which is completely different from the definition of a flash point. The flash point is the lowest temperature at which a liquid under specified test conditions gives off flammable gas or flammable vapor in such an amount that upon contact with an effective ignition source immediately a flame occurs.

Open cup flash point testing occurs when the substance is placed into a vessel which is open to the outside atmosphere. If the test is performed over a longer period of time, the oil’s fire point can be obtained. Hence, the key difference between flash point and fire point is that the flash point describes the lowest temperature at which the ignition of a substance initiates whereas the fire point describes the lowest temperature at which the fuel continues to burn for a short time period after the initiation of the ignition. Flash Point: ... it is still quite common to operate systems at temperatures above the flash point of the fluid. Ya. -The term flash point is typically used now instead of fire point. It is higher than the flash point, because at the flash point more vapor may not be produced fast enough to sustain combustion. At the flash point, a lower temperature, a substance will ignite briefly, but vapor might not be produced at a rate to sustain the fire. I believe from the definitions and the tabular highlight, the difference between ignition temperature and the fire point is clear. As the name implies (autogenous), at this temperature, ignition source is not required to ignite; it is an auto process. Also, pressure has no effect on flash point whereas increment of pressure decreases the atuo ignition temperature. However, ignition temperature is the lowest temperature at which a volatile material will be vaporised into a gas which ignites without the help of any ignition source.
