Coil coated metals - Test methods - Part 14: Chalking (Helmen method)
EN 13523-14 describes the procedure for determining objectively the chalking resulting from natural or artificial weathering of an organic coating on a metallic substrate. The advantage of this procedure for measuring chalking of an organic coating is that the result can be read off immediately on an instrument. Subjective judgement by visual comparison of test specimens with reference specimens is not necessary. Reproducible results can only be obtained by careful execution of the test. Special attention is paid to the adhesive tape and its application to the test surface. The test method is not applicable to embossed coatings. In the case of textured coatings, the degree of texture will influence readings. Also dirt collection can influence readings on outdoor weathered specimens.
Bandbeschichtete Metalle - Prüfverfahren - Teil 14: Kreiden (Verfahren nach Helmen)
Dieser Teil von EN 13523 legt das Verfahren zum objektiven Bestimmen der Kreidung einer organischen Beschichtung auf einem metallischen Substrat als Folge von Freibewitterung oder künstlicher Bewitterung fest.
Der Vorteil dieses Verfahrens zum Messen der Kreidung einer organischen Beschichtung ist, dass das Ergebnis unmittelbar an einem Messgerät abgelesen werden kann. Eine subjektive Beurteilung durch visuellen Vergleich von Proben mit Bezugsproben ist nicht erforderlich.
Vergleichbare Ergebnisse können nur erwartet werden, wenn die Prüfung sorgfältig durchgeführt wird. Besonders wird auf das Klebeband und das Aufbringen des Klebebandes auf die zu prüfende Oberfläche geachtet.
Das Prüfverfahren ist nicht anwendbar auf geprägte Beschichtungen. Bei Strukturbeschichtungen beeinflusst der Grad der Strukturierung die Ergebnisse. Auch Schmutzansammlung kann bei freibewitterten Proben die Ergebnisse beeinflussen.
ANMERKUNG Es gibt unterschiedliche Verfahren zum Beurteilen der Kreidung. Die Ergebnisse dieser unterschiedlichen Verfahren sind nicht vergleichbar.
Tôles prélaquées - Méthodes d'essai - Partie 14: Farinage (méthode Helmen)
La présente partie de l’EN 13523 décrit le mode opératoire permettant de déterminer objectivement le farinage d'un revêtement organique appliqué sur un subjectile métallique, résultant d'un vieillissement naturel ou artificiel.
L'avantage du présent mode opératoire de mesurage du farinage d'un revêtement organique est de permettre la lecture immédiate des résultats sur un instrument. Un jugement subjectif par comparaison visuelle des éprouvettes d'essai avec les éprouvettes témoins n'est pas nécessaire.
Des résultats reproductibles ne peuvent être obtenus que par une exécution soigneuse de l'essai. Une attention particulière doit être apportée à la qualité du ruban adhésif et à son application sur la surface d'essai.
Cette méthode d'essai ne s'applique pas aux revêtements emboutis. Dans le cas des revêtements texturés, le degré de texture risque d'influencer les relevés. L'accumulation de poussière peut également influencer les relevés pour les éprouvettes vieillies en extérieur.
NOTE Différentes méthodes d'évaluation du farinage peuvent être utilisées. Les résultats de ces différentes méthodes ne sont pas comparables.
Prevlečene kovine, ki se navijajo - Preskusne metode - 14. del: Kredanje (metoda po Helmenu)
Standard EN 13523-14 opisuje postopek za objektivno določitev kredanja, ki je posledica naravnega ali umetnega staranja organske prevleke na kovinski podlagi. Prednost tega postopka za merjenje kredanja organske prevleke je odčitavanje rezultatov neposredno na instrumentu. Subjektivna ocena z vizualno primerjavo preskusnih vzorcev z referenčnimi ni potrebna. Ponovljive rezultate je mogoče doseči le s skrbno izvedbo preskusa. Posebna pozornost je namenjena lepilnemu traku in njegovi uporabi na preskusni površini. Preskusna metoda se ne uporablja za žigosane prevleke. V primeru teksturiranih premazov bo stopnja teksture vplivala na odčitke. Na odčitke preskusnih vzorcev lahko vpliva tudi nabiranje umazanije na vzorcih, ki so podvrženi zunanjim vremenskim vplivom.
