1.1”This test method covers the determination of acidity as acetic acid in ethanol and ethanol solutions. This test method may be applied to ethanol samples containing very little water (dehydrated alcohols) to solutions with significant water (low proof ethanol samples). The solutions include denatured alcohols such as the U.S. denatured ethanol formulas defined in 27.CFR.Part 21. This test method is used for determining low levels of acidity, below 200 m”’kg (ppm mass), with the exclusion of carbon dioxide.
1.1.1”Procedure A”’Developed specifically for measurement of acidity by potentiometric titration. This is the referee method.
