Annex A (normative) - Specular reflectance and
specular gloss of black glass

Defines methods for the measurement of specular reflectance and specular gloss of flat samples of anodized aluminium using geometries of 20 degrees (Method A), 45 degrees (Method B), 60 degrees (Method C) and 85 degrees (Method D); and of specular reflectance by an additional 45 degrees method (Method E) employing a narrow acceptance angle.
