DESCRIPTION

BS ISO 17315:2014


This standard BS ISO 17315:2014 Petroleum products and other liquids. Ethanol. Determination of total acidity by potentiometric titration is classified in these ICS categories:
  • 75.160.40 Biofuels

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.

NOTE 1 For the purposes of this International Standard, the terms “% m/m” and “% v/v” are used to represent the mass fraction and the volume fraction of a material, respectively.

NOTE 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).
