Aluminium and aluminium alloys - Anodizing - Part 12: Measurement of reflectance characteristics of aluminium surfaces using integrating-sphere instruments
SS-EN ISO 6719:2010
This Part of this European Standard specifies a method of measuring the total and diffuse luminous reflectance characteristics of aluminium 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.
