Organization: ISO
Publication Date: 1 October 2018
Status: active
Page Count: 16
ICS Code (Paints and varnishes): 87.040
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.
