Spesifikasi Koehler K24880 Automatic Microscale Continuously Closed Cup Flash Point Analyzer
Test Method
ASTM D6450: For determination of flash point of fuel oils, lube oils, solvents and other liquids by continuously closed cup tester. The measurement is made on a test specimen of 1 mL and utilizes a closed but unsealed cup with air injected into the test chamber. This method is suitable for testing samples with a flash point from 10 °C to 250 °C.
ASTM D7094: For determination of flash point of fuels including diesel/biodiesel blends, lube oils, solvents, and other liquids by a continuously closed cup tester utilizing a specimen size of 2 mL, cup size of 7 mL, with a heating rate of 2.5 °C per minute. This test method utilizes a closed but unsealed cup with air injected into the test chamber and is suitable for testing samples with a flash point from 35 °C to 225 °C.

Description
Under specified test conditions, when a sample is heated to the temperature called flash point, the sample vapor and air mixture are ignited instantly. Flash Point is one of the indicators for the evaluation of a materials' combustion tendency. If the flash point Is low, the combustion risk would be high. As for transport and safety regulation, flash point is used for the classification of "flammable liquids". Also, flash point is used for quality control index or determining the existence of highly volatile or flammable substances in relatively nonvolatile or nonflammable matter, e.g. lubricant mixed with a small amount of diesel or gasoline.
