ECSS-Q-70-03A, SPACE PRODUCTS ASSURANCE, BLACK ANODIZING OF METALS WITH INORGANIC DYES (7 APR 2006)., The thermal control onboard spacecraft is mainly passive. It is based on the thermo-optical properties of the surfaces, namely emissivity and absorbance. The ratio of these two properties defines the equilibrium temperature of the surface. This Standard aims at providing the thermal-optical properties given by a surface treatment applied on a metallic surface to achieve an emissivity versus absorbance ratio close to unity, as requested for many applications.
