Flash point is the lowest temperature at which a liquid (usually a petroleum product) will form a vapor in the air near its surface that will “flash,” or briefly ignite, on exposure to an open flame1. Back in the late 1800s, flash point was a lived experience. Households primarily used kerosene for heat and light, and open flame was a part of every day. Bad kerosene – fuel diluted with gasoline or other contaminants – delivered unpredictable flash points and bad results. Fires and explosions were fairly common. These shared catastrophes ushered in a focused effort to establish meaningful standards for various grades of petroleum. Both ASTM2 and OSHA3 have created standard flash point measurement methods that are used today.

Of course, the importance of viscosity is well known today, and there are standard methods worldwide to ensure uniformity of testing.
