Overview

This document specifies procedures for detecting the presence of porosity in a protective paint system of any thickness on a steel or other metallic substrate. The procedures given in this document are based on methods using two different types of test equipment, the choice of equipment depending on the dry film thickness. These procedures are only applicable to the testing of electrically nonconductive parts of a paint system. The European Standard EN ISO 29601:2010 has been prepared by Technical Committee CEN/TC 139 "Paints and varnishes", the secretariat of which is held by DIN (Germany). It has been prepared by Working Group CEN/TC 139/WG 12 "Test methods and interpretation of test results of corrosion protection systems" (secretariat: DIN), together with ISO/TC 35/SC 14 "Paints and varnishes -Protective paints systems for steel structures". The responsible German committee is Subcommittee NA 002-00-10-05 GUA "Korrosionsschutzstoffe und -systeme, einschließlich Prüfung" ("Materials and systems for corrosion protection, including test methods") of Working Committee NA 002-00-10 GA "Korrosionsschutz von Stahlbauten" ("Corrosion protection of steel structures") of the Coatings and Coating Materials Standards Committee (NAB) at DIN.
