Ethanol as a blending component for petrol. Determination of total acidity. Colour indicator titration method1 Scope This European Standard specifies a method for determining the total acidity, calculated as acetic acid, of ethanol to be used in petrol blends. It is applicable to ethanol having total acid contents of between 0,003 % (m m) to 0,015 % (m m). NOTE For the purposes of this European Standard, the term % (m m) and % (V V) are used to represent the mass fraction and the volume fraction respectively. WARNING Use of this standard may involve
