At the temperature of the flash point the vapor may cease to burn when the ignition source is removed. ... The auto-ignition temperature or kindling point of a substance is the lowest temperature at which it will spontaneously ignite in a normal atmosphere without an external source of ignition, such as a flame or spark.

Is Flash Point the same as ignition temperature?
The flash point of a flammable liquid is the lowest temperature at which there will be enough flammable vapor to ignite when an ignition source is applied. Unlike flash points, the autoignition temperature does not use an ignition source. ... As a result, the autoignition temperature is higher than the flash point.
What is meant by auto ignition temperature?
2 Autoignition Temperatures. Autoignition or the kindling point is described as the lowest temperatures at which a material will spontaneously ignite under normal ambient condition without an external initiator such as a flame or a spark.
What is the difference between flash point and fire point?
The observed temperature when the flame momentarily ignites the vapor/air mixture is the Flash Point. The ignitions repeat as the liquid temperature continues to rise. The observed temperature when the burning becomes continuous is the Fire Point. Liquid is heated, but without an ignition source.
Is there any effect of temperature on Flash Point?
The flash point is determined by heating the sample of fuel in a container and passing the flame over the surface of the sample. If the temperature is at or above the flash point, the vapor will ignite and an easily detectable flash can be observed. The flash produced need not sustain for long time.
What is meant by flash point?
Flash point, the lowest temperature at which a liquid (usually a petroleum product) will form a vapour in the air near its surface that will “flash,” or briefly ignite, on exposure to an open flame. The flash point is a general indication of the flammability or combustibility of a liquid.
How do you test flash point?
This test procedure utilizes an open metal container that is filled with the sample oil. The oil is then heated at a prescribed rate and periodically a small pilot flame (ignitor) is passed over its surface. This continues until a flash appears. The oil temperature is then recorded as its flash point.
What is the lowest ignition temperature?
The minimum ignition temperature (MIT) is the lowest temperature of the furnace at which flame is observed minus 20 o C for furnace temperatures over 300 o C or minus 10 o C for furnace temperatures under 300 o C.
At what temperature does oxygen ignite?
In approximately 3 years, the flame's temperature reaches about 1.83 billion kelvins, enabling the oxygen-burning process to commence.
At what temperature does a match ignite?
1. TEMPERATURES AT FIRES
| Source | Temperature (Celsius) |
|---|---|
| Match | 600°-800° |
| Candle flame | 600°-1400° |
| Stove element | >550° |
| Fluorescent light | 60°-80° |
What comes first fire point or flash point?
The fire point is the lowest temperature at which the vapors keep burning after the ignition source is removed. It is higher than the flash point, because at the flash point more vapor may not be produced fast enough to sustain combustion.
What are the factors affecting flash point?
More factors: pressure – The flash point temperature increases with increasing pressure and decreases with decreasing pressure. Others - Tester configuration, sample size, ignition source, temperature control, sample homogeneity, drafts, and operator bias.
What is fire point of fuel?
From Wikipedia, the free encyclopedia. The fire point of a fuel is the lowest temperature at which the vapour of that fuel will continue to burn for at least five seconds after ignition by an open flame of standard dimension.
