Web26 okt. 2016 · Flash point can be measured in two ways, open cup and closed cup. In an open cup method, a flame is brought to the surface of the liquid held in an open cup. In a … WebThe flash point is an empirical measurement rather than a fundamental physical parameter. The measured value will vary with equipment and test protocol variations, including temperature ramp rate (in automated testers), time allowed for the sample to equilibrate, sample volume and whether the sample is stirred.
Webbelow the flash point. A figure often quoted is that mists can be flammable as much as 60K below flash point. However, results from Syngenta’s legacy organisation shows sprays to be flammable as much as 25K (maddison, 983) below the flash point; with no upper limit having been determined. There may be an upper limit but it will not 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).
WebIn a manual flash point test the operator is in control throughout the test, ensures that the temperature, stirring and ignition requirements are at all times and determines when and if a flash has occurred.
