Anodizing of aluminium and its alloys - Measurement of reflectance characteristics of aluminium surfaces using integrating-sphere instruments (ISO 6719:2010)

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.
