D86 Test Method

The D86 test method is a standardized procedure used in the petroleum industry to determine the initial and final boiling points of crude oil or its fractions. By gently heating a sample and recording the temperature when the first drops of liquid start to vaporize and when the last drops vaporize, it helps assess the composition and quality of the oil. This information is crucial for refining processes, enabling operators to predict how the oil will behave during processing and to optimize refining conditions responsibly and efficiently.
