D95 Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation
Based on listings from authorized resellers: Astm D95 Pdf
ASTM D95 is a pivotal standard in the oil and gas industry, ensuring the accurate determination of water and sediment in crude oil. By understanding and applying this standard, industry professionals can ensure the quality and safety of crude oil from production to refining. For detailed information and to access the standard, obtaining the ASTM D95 PDF is indispensable. Whether for quality control, custody transfer, or refining processes, adhering to ASTM D95 guidelines is crucial for operational efficiency and product integrity.
High-precision trace water analysis in refined products, turbine oils, and solvents. 7. Accessing the Official ASTM D95 PDF
: The condensed liquid falls into a graduated glass "trap." Because water is denser than the solvent and they do not mix, the water settles at the bottom of the trap. Measurement Volatile fractions yielding boiling points between 90°C and
Continue distillation until no more water is visible in any part of the apparatus except the bottom of the trap.
In high-temperature applications like asphalt processing, trapped water can rapidly flash into steam, causing dangerous foaming or explosions. 3. Apparatus and Equipment Requirements
Depending on the expected concentration of water and the sample type, laboratory technicians may choose alternative standards. Method / Standard Ideal Water Range Best Used For Distillation (Dean-Stark) 0.05% to 25% Crude oil, fuel oil, asphalt, tars, lubricants ASTM D6304 Karl Fischer Titration 10 ppm to 2.5% Ultra-low moisture in turbine oils, hydraulic fluids ASTM D4006 Distillation (Crude Oil specific) 0.005% to 2% Dedicated strictly to crude oil matrices ASTM D1796 Centrifugation (BS&W) 0.05% to 2% Field testing for water and sediment in fuel oils Why choose ASTM D95 over Karl Fischer?
