Can flash point be lower than boiling point

WebThe higher the flash point, the more safely the liquid can be handled. Liquids with flash points higher than 100°F are called combustible, whereas those under 100°F are … 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).
