This International Standard specifies a method of measuring the total and diffuse luminous reflectance characteristics of alurninium surfaces, using integrating-sphere instruments. The method described is applicable also to the measurement of specular reflectance (principal gloss value), specularity, and diffuseness. The method is unsuitable for use with lighting reflectors.
