RS ISO 6619: 1988
Petroleum products and lubricants — Neutralization number — Potentiometric titration method
Abstract

This International Standard specifies a method for the
determination of acidic constituents in petroleum products and
lubricants soluble or nearly soluble in mixtures of toluene and
propan-2-01. 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).
