The flammability of a material determines its safety classification and the regulations under which it must be handled, stored and transported. Can also be used to help detect fuel dilution.Note: A standard butane (lighter) refill cartridge is required for operation.

Flash point is the temperature at which the vapours of a fuel ignite when a test flame is applied. The flash point for all fuels to be used in bulk onboard vessels is set at 60°C minimum (SOLAS* agreement). ISO8217 Grade DMX, a special low cloud point gasoil, may only be stored onboard in drums because of its < 60°C flash point. The fuel flash point is an important quality and safety assurance measure. The flash point of biodiesel is used to detect contamination from low flashpoint methanol. Flashpoint is used in lube oils as an indication of fuel oil contamination.
