ASTM D95 is a standardized test method developed by ASTM International (formerly known as the American Society for Testing and Materials) for determining the water content in by distillation. The method quantifies water in the range of 0% to 25% by volume , making it particularly useful for applications where water contamination is a significant concern.
ASTM D95 is a critical international standard used to determine the water content in petroleum products, tars, and other bituminous materials. Understanding this standard is essential for ensuring product quality, process efficiency, and equipment protection across the global energy and manufacturing sectors. 1. What is ASTM D95?
Many petroleum products have boiling points significantly higher than water. However, simply boiling the sample may not efficiently separate the water, especially if the sample is viscous or tends to emulsify. ASTM D95 utilizes a water-immiscible solvent (typically a petroleum distillate like xylene, toluene, or a petroleum naphtha) that has a lower boiling point than water.

Measure a precise volume or mass of the sample (typically 100 mL or 100 g) into the distillation flask. Step 2: Adding Solvent and Boiling Aids
To perform this test according to the standard, labs typically use a specialized apparatus consisting of:
