BS ISO 22410:2020

This standard BS ISO 22410:2020 Corrosion of metals and alloys. Electrochemical measurement of ion transfer resistance to characterize the protective rust layer on weathering steel is classified in these ICS categories:

• 77.060 Corrosion of metals

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.
