There are two basic types of flash point measurement: open cup and closed cup. In open cup devices, the sample is contained in an open cup which is heated and, at intervals, a flame brought over the surface. The measured flash point will actually vary with the height of the flame above the liquid surface and, at sufficient height, the measured flash point temperature will coincide with the fire point. The best-known example is the Cleveland open cup (COC). WebFlash point is an excellent indication of diesel fuel contamination with more volatile products. Flash point of diesel fuels is measured according to ASTM D 93—Flash-Point by Pensky-Martens Closed Cup Tester. The sample is stirred and heated at a slow, constant rate in a closed cup.
