Water reduces the energy content of the fuel and can interfere with combustion. Where to Find ASTM D95 PDF Documents
The ASTM D95 test method is designed to measure water content within a range of . It is widely applied to various substances, including:
The water content determined by this test method is used to correct the volume or mass of the material involved in purchase, sale, and transfer transactions. In refining operations, knowledge of water content is vital for designing dehydration processes. For lubricating oils and greases, excess water can promote corrosion and alter the viscosity, making this test a critical quality control checkpoint. Astm D95 Pdf

Do not rely on outdated or pirated copies. Invest in the official standard, train your team properly, and ensure your test results meet global industry requirements.
An electric mantle or gas burner capable of precise temperature control. In refining operations, knowledge of water content is
[ \textWater content (vol%) = \fracV_wV_s \times 100 ]
Best for samples with moderate to high water content (0.1% to 25%). It handles heavily contaminated oils, crude oil, and thick bitumens exceptionally well.
