Continue distillation until no more water is visible in any part of the apparatus except the bottom of the trap.
. Unlike centrifuge methods that might miss dissolved water, ASTM D95 uses reflux distillation to physically separate water from the sample. The Science of the Distillation Method The core principle is based on the use of a water-immiscible solvent (typically xylene or toluene). Co-Distillation
Many corporate labs, universities, and testing facilities access the document via enterprise platforms like IHS Markit, Techstreet, or ANSI. Astm D95 Pdf
The co-distilled solvent and water vapors pass into a condenser and liquefy.
Water Content (% v/v)=(Volume of Water in Trap (mL)Volume of Original Sample (mL))×100Water Content (% v/v) equals open paren the fraction with numerator Volume of Water in Trap (mL) and denominator Volume of Original Sample (mL) end-fraction close paren cross 100 Mass Percentage Formula: Continue distillation until no more water is visible
The water content is typically expressed as a volume percentage (% v/v) or weight percentage (% w/w) depending on how the initial sample was measured.
