This International Standard specifies a test method for the determination of total acidity of ethanol by potentiometric titration. The total acidity is reported as acetic acid mass, in milligrams, per ethanol volume, in litres, or as mass percent of acetic acid (% m\/m), if the density of ethanol is known.<\/p>\n
\nNOTE 1 For the purposes of this International Standard, the terms \u201c% m\/m\u201d and \u201c% v\/v\u201d are used to represent the mass fraction and the volume fraction of a material, respectively.<\/p>\n<\/blockquote>\n
\nNOTE 2 This method was evaluated with ethanol samples with different water contents (0,7 % m\/m and 7 % m\/m) and acidity values (5 mg to 50 mg HAc per litre of sample).<\/p>\n<\/blockquote>\n
