1 Summary of Test Method 1.1 The test cup is filled to a specified level with the test portion. The temperature of the test portion is increased rapidly at first and then at a slow constant rate as the flash point is approached. At specified temperature intervals, a small test flame is passed across the test cup. The lowest temperature at which application of the test flame causes the vapor above the surface of the liquid to ignite is taken as the flash point at ambient barometric temperature. To determine the fire point, the test is continued until the application of the test flame causes the vapor above the test portion to ignite and burn for at least 5 s.
