This document 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.
