BS EN ISO 8251:2018

This standard BS EN ISO 8251:2018 Anodizing of aluminium and its alloys. Measurement of abrasion resistance of anodic oxidation coatings is classified in these ICS categories:

• 25.220.20 Surface treatment

This document specifies the following tests:

1. abrasive-wheel-wear test, determining the abrasion resistance of anodic oxidation coatings with abrasive wheel on flat specimens of aluminium and its alloys;

2. 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;

3. 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.
