Anodizing of aluminium and its alloys - Assessment of resistance of anodic oxidation coatings to cracking by deformation (ISO 3211:2018)

This document specifies an empirical method for assessing the resistance of anodic oxidation coatings
to cracking by deformation.
The method is applicable particularly to sheet material with anodic oxidation coatings of thickness less
than 5 μm, and is useful for development purposes.
NOTE If the test specimen is thick, more than 5 μm of coating can be measured (see Clause 9).

Anodisation de l'aluminium et de ses alliages - Évaluation de la résistance des couches anodiques à la formation de criques par déformation (ISO 3211:2017)

Le présent document spécifie une méthode empirique permettant d'évaluer la résistance des couches anodiques à la formation de criques par déformation.
La méthode est applicable particulièrement aux matériaux en feuille avec une couche anodique d'une épaisseur inférieure à 5 μm, et est utilisée pour le développement.
NOTE Si l'éprouvette est épaisse, une couche de plus de 5 μm peut être évaluée (voir Article 9).

Anodizacija aluminija in aluminijevih zlitin - Ocenjevanje odpornosti anodiziranih plasti proti razpokanju zaradi deformacije (ISO 3211:2018)

Ta dokument določa empirično metodo za ocenjevanje odpornosti anodiziranih plasti proti razpokanju zaradi deformacije.
Metoda se uporablja še zlasti za materiale v obliki plošč z anodiziranimi plastmi debeline manj kot 5 μm in je uporabna za namene razvoja.
OPOMBA: Če je preskušanec debel, se lahko izmeri več kot 5 μm plasti (glej točko 9).
