Coil coated metals - Test methods - Part 12: Resistance to scratching
This part of the EN 13523 series describes the procedure for determining the resistance of an organic coating on a metallic substrate to penetration by scratching with a needle.
It is possible that with some aluminium alloys and thin gauge steel substrate below 0,4 mm, that rather than scratching, the needle will deform the substrate. Under these conditions, this test method is not applicable.
Soft coatings such as poly vinyl chloride (PVC) and structured coatings will not give a precise result due to the soft nature of the coating and/or the potential for the needle to snag.
The method is not applicable to conductive coatings.
Bandbeschichtete Metalle - Prüfverfahren - Teil 12: Widerstand gegen Ritzen
Dieses Dokument legt ein Verfahren zum Bestimmen der Widerstandsfähigkeit einer organischen Beschichtung auf einem metallischen Substrat gegen das Eindringen eines Ritzstichels fest.
Bei einigen Aluminiumlegierungen und bei dünnem Stahlblech mit einer Dicke unter 0,4 mm kann es dazu kommen, dass der Stichel eher das Substrat verformt als die Beschichtung ritzt. Unter diesen Bedingungen ist dieses Prüfverfahren nicht anwendbar.
Bei weichen Beschichtungen, z. B. auf Polyvinylchlorid-(PVC-)Basis, und strukturierten Beschichtungen wird auf Grund der Weichheit der Beschichtung und/oder des Verhakens des Stichels kein genaues Ergebnis erhalten.
Das Verfahren ist nicht anwendbar auf leitfähige Beschichtungen.
Tôles prélaquées - Méthodes d'essai - Partie 12 : Résistance à la rayure
Le présent document spécifie le mode opératoire permettant de déterminer la résistance d’un revêtement organique appliqué sur un subjectile métallique lorsqu’il est soumis à la pénétration par rayure d’une aiguille.
Il se peut qu’avec certains alliages d’aluminium ou avec des subjectiles d’acier d’épaisseur inférieure à 0,4 mm, l’aiguille déforme le subjectile au lieu de le rayer. Dans ces conditions, cette méthode d’essai ne s’applique pas.
Les revêtements mous, tels que le chlorure de polyvinyle (PVC) et les revêtements structurés, peuvent ne pas donner de résultat précis en raison de la souplesse du revêtement et/ou du risque que l’aiguille accroche.
Cette méthode d’essai ne s’applique pas aux revêtements conducteurs.
