Coil coated metals - Test methods - Part 12: Resistance to scratching

This part of EN 13523 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

Dieser Teil der Normenreihe EN 13523 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 Ergeb-nis erhalten.
Das Verfahren ist nicht anwendbar auf leitfähige Beschichtungen.

Tôles prélaquées - Méthodes d'essai - Partie 12 : Résistance à la rayure

La présente partie de l'EN 13523 décrit le mode opératoire permettant de déterminer la résistance d'un revêtement organique recouvrant un subjectile métallique à la pénétration par rayure à l'aide 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 n'est pas applicable.
Les revêtements mous, comme 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.
La méthode n'est pas applicable aux revêtements conducteurs.

Prevlečene kovine, ki se navijajo - Preskusne metode - 12. del: Odpornost proti razenju

Ta del standarda EN 13523 opisuje postopek za ugotavljanje odpornosti organske prevleke na kovinski podlagi proti prediranju pri razenju z iglo.
Pri nekaterih aluminijevih zlitinah in tankih pločevinastih podlagah z debelino manj kot 0,4 mm je možno, da bo namesto razenja igla deformirala podlago. Pri teh pogojih se ta metoda ne uporablja.
Pri mehkih prevlekah iz npr. polivinilklorida (PVC) in strukturiranih prevlekah ne bo natančnih rezultatov zaradi mehkobe prevleke in/ali možnosti zatikanja igle.
Metoda se ne uporablja za prevodne prevleke.
