Understanding ASTM D95: The Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation
If you're unable to access the PDF through these channels, you may want to consider contacting ASTM directly or consulting with a local standards organization for assistance.
Yes—the method measures (free, emulsified, and dissolved) because the distillation process extracts all water from the sample.

A glass reflux condenser (usually a straight-tube or Liebig type) with a jacket length of 400 mm ensures complete condensation of volatile vapors. 3. Graduated Glass Trap

Water in fuel tanks promotes the growth of bacteria and fungi, leading to filter clogging.
Ensure the sample is completely homogenous. Thoroughly mix the liquid petroleum or heat viscous bituminous materials until fluid before taking a representative aliquot. Measure a precise volume or mass of the sample (usually 100 mL or 100 g) and transfer it into the distillation flask. Step 2: Solvent Addition

Typically 30 minutes to 2 hours, depending on the sample’s viscosity and water content.
ASTM D95, titled "Standard Test Method for Water and Sediment in Crude Oil by Centrifuge," is a widely adopted standard that outlines a procedure for determining the water and sediment content in crude oils. This test method is essential for assessing the quality of crude oil, influencing everything from processing and refining efficiencies to the overall cost and quality of petroleum products.
