Coil coated metals - Test methods - Part 4: Pencil hardness

This part of EN 13523 describes the procedure to assess the relative hardness of an organic coating on a metallic substrate, by means of pencils of known hardness.
Smooth surfaces will give more accurate results but the method is also applicable for textured surfaces. The more pronounced the texture, the greater the unreliability of results.

Bandbeschichtete Metalle - Prüfverfahren - Teil 4: Bleistifthärte

Dieser Teil von EN 13523 legt das Verfahren zum Bestimmen der relativen Härte einer organischen Beschichtung auf einem metallischen Substrat mit Hilfe von Bleistiften bekannter Härte fest.
Auf glatten Oberflächen werden genauere Ergebnisse erhalten, aber das Verfahren ist auch bei strukturierten Oberflächen anwendbar. Je ausgeprägter die Struktur ist, desto größer ist die Unsicherheit der Ergebnisse.

Tôles prélaquées - Méthodes d'essai - Partie 4: Dureté crayon

La présente partie de l'EN 13523 décrit la méthode de détermination de la dureté relative d'un revêtement organique sur un subjectile métallique, au moyen de crayons de dureté connue.
Les surfaces lisses donnent des résultats plus précis, mais la méthode s’applique également aux surfaces texturées. Plus la texture est prononcée, moins les résultats sont fiables.

Prevlečene kovine, ki se navijajo - Preskusne metode - 4. del: Merjenje trdote s svinčnikom

Standard EN 13523-4 opisuje postopek za ocenjevanje relativne trdote organske prevleke na kovinski podlagi s pomočjo svinčnikov z znano trdoto. Gladke površine sicer kažejo natančnejše rezultate, vendar je metodo mogoče uporabiti tudi pri teksturiranih površinah. Večja izrazitost teksture pomeni večjo nezanesljivost rezultatov.
