1.1 This test method covers procedures for the determination of acidic constituents in petroleum products, lubricants, biodiesel and blends of biodiesel.
1.1.1 Test Method A-For petroleum products and lubricants soluble or nearly soluble in mixtures of toluene and propan-2-ol. It is applicable for the determination of acids whose dissociation constants in water are larger than 10-9; extremely weak acids whose dissociation constants are smaller than 10-9 do not interfere. Salts react if their hydrolysis constants are larger than 10-9. The range of acid numbers included in the precision statement is 0.1 mg/g KOH to 150 mg/g KOH.
