Paints and varnishes - Cross-cut test (ISO 2409:2007)

ISO 2409:2007 describes a test method for assessing the resistance of paint coatings to separation from substrates when a right-angle lattice pattern is cut into the coating, penetrating through to the substrate. The property measured by this empirical test procedure depends, among other factors, on the adhesion of the coating to either the preceding coat or the substrate. This procedure is not to be regarded, however, as a means of measuring adhesion.
The method described may be used either as a pass/fail test or, where circumstances are appropriate, as a six-step classification test. When applied to a multi-coat system, assessment of the resistance to separation of individual layers of the coating from each other may be made.
The test can be carried out on finished objects and/or on specially prepared test specimens.
The method is not suitable for coatings of total thickness greater than 250 micrometres or for textured coatings.

Beschichtungsstoffe - Gitterschnittprüfung (ISO 2409:2007)

Diese Internationale Norm legt ein Prüfverfahren zur Abschätzung des Widerstandes einer Beschichtung gegen Trennung vom Substrat fest, wenn ein bis zum Substrat durchgehendes Gitter in die Beschichtung geschnitten wird. Die nach diesem empirischen Verfahren gemessene Eigenschaft hängt, neben anderen Faktoren, von der Haftfestigkeit der Beschichtung auf der vorhergehenden Schicht oder auf dem Substrat ab. Dieses Verfahren ist jedoch nicht als Verfahren zur Messung der Haftfestigkeit anzusehen.
Wenn die Haftfestigkeit gemessen werden soll, kann das in ISO 4624 festgelegte Verfahren angewendet werden.
ANMERKUNG 1   Obwohl die Gitterschnittprüfung in erster Linie zur Anwendung im Laboratorium gedacht ist, ist sie auch als Feldprüfung geeignet.
Das festgelegte Verfahren kann entweder als ja/nein-Prüfung oder, wenn entsprechende Umstände gegeben sind, als Einstufungsprüfung mit sechs Stufen angewendet werden. Bei Mehrschichtsystemen kann auch die Zwischenschicht-Haftfestigkeit abgeschätzt werden.
Die Prüfung kann an fertigen Gegenständen und/oder an eigens dafür hergestellten Probeplatten durchge¬führt werden.
Obwohl das Verfahren auf Beschichtungen auf harten (Stahl) und weichen (Holz und Putz) Substraten anwendbar ist, erfordern diese unterschiedlichen Substrate eine unterschiedliche Durchführung (siehe Abschnitt 6).
Das Verfahren ist für Beschichtungen mit einer Gesamtschichtdicke über 250 µm oder für Struktur¬beschich¬tungen nicht geeignet.
ANMERKUNG 2   Wenn das Verfahren auf Beschichtungen mit einer strukturierten Oberfläche angewendet wird, streuen die Ergebnisse zu stark (siehe auch ISO 16276-2).

Peintures et vernis - Essai de quadrillage (ISO 2409:2007)

L'ISO 2409:2007 décrit une méthode d'essai pour l'évaluation de la résistance des revêtements de peinture à être séparés de leurs subjectiles lorsqu'on pratique dans le revêtement un quadrillage par incisions jusqu'au subjectile. La propriété évaluée par cette méthode empirique dépend, entre autres, de l'adhérence de la couche soit à la couche précédente, soit au subjectile. Cette méthode ne peut, cependant, être considérée comme un moyen de mesurer l'adhérence.
La méthode décrite peut être utilisée soit comme essai «tout ou rien», soit, le cas échéant, comme essai en vue d'une classification en six niveaux. Lorsqu'il est appliqué à un système multicouches, le mode opératoire permet également d'évaluer la résistance des couches individuelles du revêtement à se séparer les unes des autres.
L'essai peut être réalisé sur des objets finis et/ou sur des éprouvettes spécialement préparées.
La méthode ne convient ni aux revêtements dont l'épaisseur totale dépasse 250 micromètres, ni aux revêtements texturés.
