Anodizing of aluminium and its alloys - Measurement of abrasion resistance of anodic oxidation coatings (ISO 8251:2018)

This document specifies the following tests:
a)    abrasive-wheel-wear test, determining the abrasion resistance of anodic oxidation coatings with abrasive wheel on flat specimens of aluminium and its alloys;
b)    abrasive jet test, determining the comparative abrasion resistance of anodic oxidation coatings with jet of abrasive particles on anodic oxidation coatings of aluminium and its alloys;
c)    falling sand abrasion test, determining the abrasion resistance of anodic oxidation coatings with falling sand on thin anodic oxidation coatings of aluminium and its alloys.
The use of abrasive-wheel-wear test and abrasive jet test for coatings produced by hard anodizing is described in ISO 10074.

Anodisation de l'aluminium et de ses alliages - Détermination de la résistance à l'abrasion des couches d'oxyde anodiques (ISO 8251:2018)

Le présent document spécifie les essais suivants:
a)    essai d'usure à la roue abrasive, qui détermine la résistance à l'abrasion de couches d'oxyde anodiques par une roue abrasive sur des éprouvettes plates d'aluminium et de ses alliages;
b)    essai au jet abrasif, qui détermine la résistance comparée à l'abrasion de couches d'oxyde anodiques par un jet de particules abrasives sur des couches d'oxyde anodiques en aluminium ou ses alliages;
c)    essai d'abrasion par chute de sable, qui détermine la résistance à l'abrasion de couches d'oxyde anodiques par chute de sable sur des couches d'oxyde anodiques minces en aluminium ou ses alliages.
L'application de l'essai d'usure à la roue abrasive et de l'essai au jet abrasif 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 8251:2018)

Ta dokument določa naslednje preskuse:
a) preskus obrabe z brusilnim kolutom, ki določa obrabno odpornost anodno oksidiranih prevlek z uporabo brusilnega koluta na ploščatih vzorcih aluminija in aluminijevih zlitin;
b) preskus obrabe z brusilnim curkom, ki določa primerjalno obrabno odpornost anodno oksidiranih prevlek z uporabo curka brusilnih delcev na anodno oksidiranih prevlekah aluminija in aluminijevih zlitin;
c) brusilni preskus s padajočim peskom, ki določa obrabno odpornost anodno oksidiranih prevlek z uporabo padajočega peska na tankih anodno oksidiranih prevlekah aluminija in aluminijevih zlitin.
Uporaba preskusa obrabe z brusilnim kolutom in preskusa obrabe z brusilnim curkom pri prevlekah, izdelanih s trdno anodizacijo, je opisana v standardu ISO 10074.
