77.060 - Corrosion of metals

ISO 22410

This document specifies a method for the electrochemical measurement of ion transfer resistance of the rust layer formed on weathering steel alloys in order to assess their protective properties against corrosion thereafter^{[ 3]}. This method uses an electrochemical AC impedance measurement^{[ 4][ 5][ 6][ 7][ 8]}_, together with harmonic analysis, to identify the ion transfer resistance, and a rust thickness measurement to characterize the stability of the protective rust layer in terms of corrosion protection under used environments.
