Corrosion protection of steel structures by protective paint systems — Assessment of, and acceptance criteria for, the adhesion/cohesion (fracture strength) of a coating — Part 2: Cross-cut testing and X-cut testing

Protection contre la corrosion des structures en acier par systèmes de peinture — Évaluation et critères d’acceptation de l’adhésion/cohésion (résistance à la rupture) d’un revêtement — Partie 2: Essai de quadrillage et essai à la croix de Saint André

Abstract / scope

This document specifies procedures for assessing the resistance of paint systems when a cut in the form of a right-angle lattice pattern (cross-cut) or in the form of an X (X-cut) is made into the paint, penetrating through to the substrate. This document is only applicable if the cross-cut or X-cut test method is specified, together with the rating from the appropriate rating scale.

This document also specifies suitable equipment and defines inspection areas, sampling plans and acceptance/rejection criteria.

It does not specify ratings for particular coating systems.
