Anodized aluminium and aluminium alloys -- Measurement of specular reflectance and specular gloss at angles of 20 degrees, 45 degrees, 60 degrees or 85 degrees
This standard has been revised by ISO 7668:2010.
ISO 7668 constitutes a revision in parts of ISO 2767:1973. The measurement is intended mainly for use with clear anodized surfaces. It can be used with colour-anodized aluminium, but then only for similar colours.
