Flash Point and Autoignition Temperatures of Common Vehicle Fluids. In a historic step for climate change action the British government has pledged to ban the sale of new petrol and diesel cars by 2030. The flash point is often used as a descriptive characteristic of the liquid fuel, and it is also used to help characterizing the fire hazards of liquids. Flash Point: The temperature at which the vapors produced from a fluid will ignite (flash off) with the presence of an ignition source (the fluid will not burn at this point). At specific temperature intervals (1 or 2 °C), the cup is opened and an ignition source is moved over the top of the cup. Fuel For Thought Ignition temperature means the same thing as autoignition temperature according to Merriam Webster. St Albans The flash point of a volatile material is the lowest temperature needed to evaporate enough fluid to form a combustible concentration of gas. Laboratory Measurements .
