Anodizing of aluminium and its alloys - Measurement of abrasion resistance of anodic oxidation coatings (ISO 8251:2011)

ISO 8251:2011 specifies the following three test methods: a) abrasive-wheel-wear test method, determining the wear resistance and the wear index of anodic oxidation coatings on flat specimens of aluminium and its alloys; b) abrasive jet test method, comparing the resistance to abrasion of anodic oxidation coatings on aluminium and its alloys with that of a standard specimen or, alternatively, a reference specimen, by use of a jet of abrasive particles; c) falling sand abrasion method, determining the abrasion resistance with falling sand applied to thin anodic oxidation coatings.
The use of these methods for coatings produced by hard anodizing is described in ISO 10074.

Anodisieren von Aluminium und Aluminiumlegierungen - Messung der Abriebfestigkeit von anodisch erzeugten Oxidschichten (ISO 8251:2011)

Diese Internationale Norm legt die folgenden drei Prüfverfahren fest:
a) Abriebprüfverfahren mit Schleifscheibe, das die Abriebfestigkeit und die Abriebzahl von anodisch
erzeugten Oxidschichten auf flachen Proben aus Aluminium und Aluminiumlegierungen ermittelt;
b) Abriebprüfverfahren mit Schleifmittelstrahl, das die Abriebfestigkeit von anodisch erzeugten
Oxidschichten auf Aluminium und Aluminiumlegierungen mit der Abriebfestigkeit entweder einer Normprobe
oder einer Referenzprobe vergleicht, mithilfe eines Strahls von Schleifmitteln;
c) Abriebprüfverfahren mit fallendem Sand, das die Abriebfestigkeit mithilfe von fallendem Sand
bestimmt und für dünne, anodisch erzeugte Oxidschichten anwendbar ist.
Die Anwendung dieser Verfahren an Schichten, die durch Hartanodisieren erzeugt wurden, ist in ISO 10074
beschrieben.

Anodisation de l'aluminium et de ses alliages - Détermination de la résistance à l'abrasion des couches d'oxyde anodiques (ISO 8251:2011)

L'ISO 8251:2011 spécifie les trois méthodes d'essai suivantes: a) méthode d'essai d'usure à la roue abrasive, qui détermine la résistance à l'usure et de l'indice d'usure de couches anodiques formées sur des échantillons plats d'aluminium ou d'un de ses alliages; b) méthode d'essai au jet abrasif, qui compare la résistance à l'abrasion de couches anodiques formées sur l'aluminium ou l'un de ses alliages avec celle d'un échantillon normalisé ou, en variante, celle d'un échantillon de référence, à l'aide d'un jet de particules abrasives; c) méthode d'abrasion par chute de sable, qui détermine la résistance à l'abrasion par chute de sable appliquée à des couches anodiques minces.
L'application de ces méthodes à des couches produites par anodisation dure est décrite dans l'ISO 10074.

Anodizacija aluminija in aluminijevih zlitin - Meritve obrabne obstojnosti anodno oksidiranih prevlek (ISO 8251:2011)

Ta mednarodni standard določa naslednje tri preskusne metode: a) metoda s preskusom obrabe z brusilnim kolutom, ki določa obrabno odpornost in obrabno število anodno oksidiranih prevlek na ploščatih vzorcih aluminija in njegovih zlitin; b) metoda s preskusom obrabe z brusilnim curkom, ki primerja obrabno odpornost anodno oksidiranih plasti na aluminiju in njegovih zlitinah z obrabno odpornostjo na standardnem vzorcu ali alternativno na referenčnem vzorcu z uporabo curka brusilnih delcev; c) brusilna metoda s padajočim peskom, ki določa obrabno odpornost s padajočim peskom, uporabljenim na tankih anodno oksidiranih prevlekah. Uporaba teh metod pri prevlekah, izdelanih s trdno anodizacijo, je opisana v ISO 10074.
