Jet fuel flash points also vary with the composition of the fuel. Both Jet A and Jet A-1 have flash points between 38 and 66 °C (100 and 151 °F), close to that of off-the-shelf kerosene. Yet both Jet B and JP-4 have flash points between −23 and −1 °C (−9 and 30 °F).
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

The flash point of most blends of No. 6 oil is, incidentally, about 65 °C (149 °F). ... Number 5 fuel oil is a residual-type industrial heating oil requiring ...
A flammable liquid is a liquid having a flash point of not more than 60 °C (140 °F), or any material in a liquid phase with a flash point at or above 37.8 °C (100 °F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging. The following exceptions apply:
Number 2 fuel oil has a flash point of 52 °C (126 °F). Historically, the legal difference between diesel and heating oil in the United States has been sulfur allowance. Diesel for machinery and equipment must be below 15 ppm sulfur content while heating oil needed only stay below 500 ppm sulfur.
A blend of approximately 30% kerosene and 70% gasoline, it is known as wide-cut fuel. It has a very low freezing point of −60 °C (−76 °F), and a low flash point as well. It is primarily used in northern Canada and Alaska, where the extreme cold makes its low freezing point necessary, and which helps mitigate the danger of its lower flash ...
Gasoline is flammable with low flash point of −23 °C (−9 °F). Gasoline has a lower explosive limit of 1.4 percent by volume and an upper explosive limit of 7.6 ...
National and international standards define the properties of several grades of kerosene used for jet fuel. Flash point and freezing point properties are particularly interesting for operation and safety; the standards also define additives for control of static electricity and other purposes.
