flashing point

noun

, Physical Chemistry.

First recorded in 1875–80

This flashing point is the temperature at which the vapor from the kerosene explodes or flashes.

When of good quality it is nearly colorless, and the flashing point should be 149 F., or 65 C.

The flashing test should, therefore, be the only test, and the higher the flashing point the safer the oil.

The flashing test determines the flashing point of the oil, or the lowest temperature at which it gives off an inflammable vapor.

The burning point of an oil is from ten to fifty degrees Fahrenheit higher than the flashing point.
