Paints and varnishes - Determination of resistance to filiform corrosion - Part 1: Steel substrates (ISO 4623-1:2018)

Scope

This document describes a test procedure for assessing the protective action of coatings of paints or varnishes on steel against filiform corrosion arising from a scribed mark cut through the coating.
It is only suitable for assessing the performance of the coating/substrate combination tested. It is not suitable for predicting the performance of the coating on different substrates.
