A water-cooled glass reflux condenser (usually a straight-tube or Liebeg type) is placed vertically on top of the trap to ensure all vapors return to liquid form. 4. Step-by-Step Test Procedure

Volatile spirits are used as the carrier liquid for testing greases. 2. Principle of the Method (Dean-Stark Distillation)

The ASTM D95 test method involves centrifuging a sample of crude oil to separate the water and sediment from the oil. The process is relatively straightforward: Astm D95 Pdf

ASTM D95 specifies a test method to quantify the amount of water present in petroleum and bituminous matrices. It covers a range from 0% to 25% water by volume.

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? It covers a range from 0% to 25% water by volume

To ensure you are working with the correct, current, and legally valid version of the standard, you must obtain it from official sources.

A specialized glass trap (Dean-Stark receiver) graduated in fractions of a milliliter (commonly 5 mL, 10 mL, or 25 mL capacities). 2. Solvents and Reagents If you want

A specialized glass trap (often a Dean-Stark apparatus) graduated from 0 to 2 mL, 5 mL, 10 mL, or 25 mL, depending on the expected water content.

Apply heat to the flask. Adjust the temperature so that the condensate falls from the condenser tip at a steady rate of 2 to 5 drops per second.
