Anodizing of aluminium and its alloys - Evaluation of uniformity of appearance of architectural anodic finishes - Determination of diffuse reflectance and specular gloss
This International Standard specifies a method of determining the diffuse reflectance and specular gloss of architectural anodic finishes on aluminium and its alloys in order to evaluate their uniformity of appearance. The method is intended for use as a rapid in-plant technique.
It is suitable for most finishes, including those produced by integral colour anodizing, those having electrolytically im-pregnated colours, as well as coloured anodic oxide coatings produced using organic or inorganic dyes.
