Overview

Passive thermal control systems on board spacecraft are often 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 provides requirements for black-anodizing surface treatment applied on metallic surfaces to achieve an emissivity versus absorbance ratio close to unity, as requested for many applications. This standard defines requirements for measurements and verifications to guarantee that an anodized coating is adequate for the intended application. The requirements set by this standard ensure high reliability of surface treatments intended to withstand normal terrestrial conditions and environment loads imposed on spacecraft and associated equipment where surfaces require high solar absorptance, high emittance, high optical blackness, or a combination of these properties. This standard may be tailored for the specific characteristics and constraints of a space project, in conformance with ECSS-S-ST-00. This document (EN 16602-70-03:2014) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document has been developed to cover specifically space systems and has therefore precedence over any European Standard covering the same scope but with a wider domain of applicability (for example: aerospace).
