Anodizing of aluminium and its alloys — Accelerated test of light fastness of coloured anodic oxidation coatings using artificial light
|Publication Date:||15 February 2010|
|ICS Code (Surface treatment):||25.220.20|
This International Standard specifies an accelerated test method for assessing the fastness, using artificial light, of coloured anodic oxidation coatings on aluminium and its alloys.
For evaluating light fastness on exterior exposure, only outdoor exposure under conditions comparable to actual service is completely satisfactory.
Accelerated testing is suitable as a quality-control test of coloured anodic oxidation coatings whose lightfastness number has already been established by means of outdoor exposure testing.
The method is applicable to coloured anodic oxidation coatings on aluminium and its alloys produced by any means and for any purpose.
However, the method is not suitable for the measurement of coloured coatings with a light-fastness number already established by means of outdoor exposure testing, and of less than 6.
