ASTM D1550

ASTM D1550 is a standardized test method used to determine the minimum flash point of aviation turbine fuels. The flash point is the lowest temperature at which a fuel can produce enough vapor to ignite in the presence of an open flame. This test helps ensure fuel safety by establishing the temperature at which the fuel becomes flammable, aiding in quality control and safe handling. The procedure involves gradually heating a fuel sample in a controlled environment and applying a small flame at intervals to find the lowest temperature that causes ignition.
