Anodizing of aluminium and its alloys - Estimation of loss of absorptive power of anodic oxidation coatings after sealing - Dye-spot test with prior acid treatment (ISO 2143:2010)

ISO 2143:2010 specifies a method of estimating the loss of absorptive power of anodic oxidation coatings that have undergone a sealing treatment, by dye absorption after acid pretreatment.
The method is suitable for use as a production control method and is applicable to anodic oxidation coatings which may be subjected to weathering or aggressive environments, or where resistance to staining is important.
The method is not applicable to those coatings that: a) are formed on alloys containing more than 2 % copper or 4 % silicon; b) are sealed by the dichromate process; c) have been given supplementary processing, e.g. oiling, waxing or lacquering; d) are coloured in deep shades; e) are less than 3 μm thick.
The method is less appropriate where nickel or cobalt salts, or organic additives, have been added to the sealing bath.

Anodisieren von Aluminium und Aluminiumlegierungen - Abschätzung der Anfärbbarkeit von anodisch erzeugten Oxidschichten nach dem Verdichten - Farbtropfentest mit vorheriger Säurebehandlung (ISO/FDIS 2143:2010)

Diese Internationale Norm legt ein Verfahren zur Abschätzung der Anfärbbarkeit von verdichteten, anodisch
erzeugten Oxidschichten durch den Farbtropfentest mit vorheriger Säurebehandlung fest.
Das Verfahren ist zur Produktionsüberwachung geeignet und auf anodisch erzeugte Oxidschichten
anwendbar, die einer Bewitterung oder aggressiven Umwelteinflüssen ausgesetzt werden oder bei denen eine
Widerstandsfähigkeit gegenüber Fleckenbildung wichtig ist.
Das Verfahren ist nicht für Schichten anwendbar, die:
a) auf Legierungen, die mehr als 2 % Kupfer oder 4 % Silicium enthalten, erzeugt wurden;
b) in Dichromatlösungen verdichtet wurden;
c) einer zusätzlichen Behandlung unterzogen wurden, z. B. Einölen, Einwachsen oder Lackieren;
d) in dunklen Farbtönen eingefärbt sind;
e) eine Schichtdicke von weniger als 3 μm aufweisen.
Das Verfahren ist weniger geeignet, wenn dem Verdichtungsbad Nickel- oder Cobaltsalze oder organische
Zusätze zugesetzt wurden.

Anodisation de l'aluminium et de ses alliages - Appréciation de la perte du pouvoir absorbant des couches anodiques après colmatage - Essai à la goutte de colorant avec action acide préalable (ISO 2143:2010)

L'ISO 2143:2010 spécifie une méthode permettant d'apprécier la perte du pouvoir absorbant des couches anodiques ayant subi un traitement de colmatage, par un essai de coloration après une action acide préalable.
La méthode convient au contrôle de production et s'applique aux couches anodiques qui peuvent être soumises aux intempéries ou à des milieux agressifs, ou lorsque la résistance aux taches est importante.
La méthode n'est pas applicable aux couches qui:
sont formées sur les alliages contenant plus de 2 % de cuivre ou 4 % de silicium,
sont colmatées dans des solutions contenant du dichromate,
ont subi un traitement supplémentaire; par exemple huile, cire ou laque,
sont colorées de couleurs foncées, ou
ont une épaisseur inférieure à 3 µm.
La méthode est moins appropriée lorsque des sels de nickel ou de cobalt ou des additifs organiques ont été ajoutés au bain de colmatage.

Anodizacija aluminija in aluminijevih zlitin - Ocena izgube moči absorbirnosti anodnooksidiranih prevlek po tesnjenju por - Kapljični preskus z barvilom ob predhodni kislinski obdelavi (ISO 2143:2010)

Ta mednarodni standard določa metodo ocenjevanja izgube moči absorbirnosti anodno oksidiranih prevlek, ki so bile podvržene postopku tesnjenja z absorpcijo barvila, ki sledi predhodni kislinski obdelavi. Ta metoda je primerna, da se uporablja kot metoda za kontrolo proizvodnje, ter se uporablja za anodno oksidirane prevleke, ki so lahko podvržene preperevanju ali agresivnim okoljem, ali kjer je pomembna odpornost proti madežem.  Metoda ni primerna za prevleke, ki:
a) nastanejo na zlitinah, katere vsebujejo več kot 2 % bakra in 4 % silicija;
b) so tesnjene z dvobarvnim postopkom;  
c) so bile dodatno obdelane, npr. z oljenjem, voskanjem ali lakirane;
d) so barvane v temnih odtenkih;
e) so debele manj kot 3 μm.
Metoda je manj primerna, kadar so bili kopeli za tesnjenje dodana nikljeva ali kobaltova sol ali organski dodatki.
