DUS 1753:2017, Standard Test Method for Acidity in Ethanol and Ethanol Blends by Titration. (10 pages, in English)

This draft test method covers the determination of acidity as acetic acid (see Specification D4806) in commonly available grades of denatured ethanol, and ethanol blends with gasoline ranging from E95 to E30. This test method is used for determining low levels of acidity, below 200 mg⁄kg (ppm mass), with the exclusion of carbon dioxide.
