This document describes the procedure for determination of the acidity of petrol, kerosene, gas oils for industrial and municipal purposes, diesel fuels and the acid number of non-inhibited oils soluble in a mixture of ethanol and toluene or xylene.
Two methods are described:
Method A: Determination of acidity and acid number by titration with a solution of potassium hydroxide in ethanol.
Method B: Determination of the acid number by titration with a solution of potassium hydroxide in propan-2-ol in an atmosphere free of carbon dioxide.
Methods for determination of acid number can also be used for inhibited oils, if it is indicated in the product specification.
