Aluminium and aluminium alloys. Anodizing. Measurement of specular reflectance and specular gloss of anodic oxidation coatings at angles of 20$0D, 45$0D, 60$0D, and 85$0D (British Standard)
This part of this European Standard specifies methods for the measurement of specular reflectance and specular gloss of flat samples of anodized aluminium using geometries of 20° (method A), 45° (method B), 60° (method C) and 85° (method D), and of specular reflectance by an additional 45° method (method E) employing a narrow acceptance angle. The methods described are intended mainly for use with clear anodized surfaces. They can be used with colour-anodized aluminium, but only with similar colours.
