Abstract
Overview
ISO 4947:2020 - Steel and cast iron - Determination of vanadium content - Potentiometric titration method specifies a laboratory procedure for measuring vanadium in steel and cast iron. The method uses potentiometric titration and is applicable to vanadium mass fractions from . This second edition (2020) updates the original 1986 standard, introduces an optional electrode and reassesses precision data.
