Space systems - Prevention of break-up of unmanned spacecraft
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.
Space systems - Thermal control coatings for spacecraft - General requirements
This International Standard specifies the multiple measurement methods, instruments, equipment, and samples used to calculate the thermo-optical properties of thermal control materials. This International Standard compares their features, indicates their limitations and biases, and guides the applications. These measurements will be performed at ground test facilities with the purpose of obtaining material properties. The measured properties will be used for material selection, thermal design of spacecraft,process control, quality control, etc. Also, on-orbit temperature data in the beginning of life can be assessed using the data obtained by ground measurement. Requirements for calibration and reference materials to ensure data quality are also defined.
Space systems.Measurements of thermo-optical properties of thermal control materials
This Technical Report is a guide for establishing essential collaborative enterprises to sustain the space environment and employ it effectively. This requires diligent collaboration among all who operate satellites. This Technical Report describes some widely used techniques for perceiving close approaches,estimating collision probability, estimating the cumulative probability of survival, and manoeuvring to avoid collisions.

Process management for avionics - Aerospace and defence electronic systems containing lead-free solder - Part 3: Performance testing for systems containing lead-free solder and finishes (IEC 107/213/DTS:2013)
Space systems. Simulation requirements for control system
This International Standard presents the requirements for Requirements Management (RM) for space projects. This International Standard addresses the space programme/project management requirements,applicable through a top-down approach in a contractual relationship between customers and suppliers. The objective of this International Standard is to state and establish a common reference framework for all the customers and suppliers in the space sector to deploy Requirements Management for all space products and projects.
