Anodizing of aluminium and its alloys. Measurement of reflectance characteristics of aluminium surfaces using integrating-sphere instruments Ingestion-build-47553 in four accuracy grades1 Scope This International Standard specifies a method of measuring the total and diffuse luminous reflectance characteristics of aluminium surfaces, using integrating sphere instruments. The method described is also applicable to the measurement of specular reflectance (principal gloss value), specularity and diffuseness. The method is unsuitable for use with lighting reflectors.
