Anodizing of aluminium and its alloys - Determination of the comparative fastness to ultraviolet light and heat of coloured anodic oxidation coatings (ISO 6581:2010); German version EN ISO 6581:2010
Anodisieren von Aluminium und Aluminiumlegierungen - Vergleichsbestimmung der Beständigkeit von gefärbten, anodisch erzeugten Oxidschichten gegen ultraviolettes Licht und Wärme (ISO 6581:2010); Deutsche Fassung EN ISO 6581:2010
Overview
This document specifies a comparative method for the determination of the fastness of coloured anodic oxidation coatings to ultraviolet light and heat. The method is not suitable for testing of coloured anodic oxidation coatings that are very heat sensitive. Dark-coloured test pieces will normally reach the highest temperatures. Testing will occur according to the following principle: exposure of test pieces to ultraviolet light and observation of occurring colour changes taking place by comparison with standard or control specimens. The International/European Standard has been prepared under the leadership of ISO/TC 79/SC 2/WG 16 "Revisions for Systematic reviewed TC 79/SC 2 ISO standards" (secretariat: JISC, Japan) in a parallel procedure with CEN/TC 132/WG 15 "Aluminium anodisation" (secretariat: BSI, United Kingdom). On the national level the responsible Working Committee is NA 066-01-09 AA "Anodisch oxidiertes Aluminium" ("Aluminium anodisation") of FNNE.
