适用范围

This International Standard specifies methods for the measure-ment of specular reflectance and specular gloss of flat samples of aluminium or anodized aluminium and its alloys 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 E) employing a narrow acceptance angle, These methods are intended mainly for use with clear anodized surfaces. They can be used with colour-anodized aluminium, but then only for similar colours.
