Flash point device according to ASTM D 92 standard method
This test method is used to measure the flash point temperature and flash point of all petroleum and hydrocarbon products and cuts that have a flash point of at least 79 and a maximum of 380 degrees Celsius.
The Clevland open-cup method is used to measure the open flash point of all petroleum products with an open flash point in the temperature range of at least 79 and at a maximum of 400 ° C, except for furnace oil.
This test method uses the ASTM 11C / IP 28C thermometer or an electronic temperature measuring device such as a resistance thermometer or thermocouple or the like. Provided that the temperature is the same as that of mercury thermometers.
In this test method, the heating rate of the sample is such that the test temperature rises from 28 ° C below the expected flash point to a speed of 5 to 6 ° C per minute, and with every 2 ° C increase in temperature, the ignition source passes through the test. .
