The pour point of a liquid is the temperature below which the liquid loses its flow characteristics. It is defined as the minimum temperature in which the oil has the ability to pour down from a beaker.

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). WebThe flash point of ethanol, acetone, acetic acid and formic acid aqueous solutions was measured using Abel and Pensky-Martens in close cup methods, chosen regarding predicted values of flash point. Results obtained show that, for the most flammable products, such as acetone or ethanol, weakly
