This test method covers the determination of water from 0 to 1.5 % by mass in blends of ethanol and hydrocarbon. It is intended for measuring water content of gasoline or other hydrocarbon blendstock, denatured fuel ethanol as cited in D4806, and ethanol fuel blends such as those cited in Specification D5798 and Practice D7794.
The proposed method will be used by the refining and ethanol industries. Currently, specifications D4806 (ethanol) and D5798 (E85) designate water test methods that were not validated for ethanol and are outside the jurisdiction of ASTM D2. In addition to specification limits, water content is also needed for D5501 ethanol content calculations.
The title and scope are in draft form and are under development within this ASTM Committee.Back to Top
