Space systems. Thermal control coatings for spacecraft. General requirements. | Status: Current, Confirmed

1 Scope This International Standard defines general requirements for thermal control coatings (TCC) that are applied on metallic and/or non-metallic surfaces of spacecraft and payloads in order to provide the following thermo-optical properties:

• — αs: solar absorptance;
• — ε: emittance.

The function of TCC is to reduce external heat absorption and/or to regulate radiant heat exchange between on-board equipment on spacecraft.
