ISO/TC 20/SC 14/WG 6 - Materials and processes

This document establishes the main requirements for: — a choice of coating materials and coatings for space applications; — processes and procedures for the verification of coating materials; — processes of preparation and quality control of the painted surface; — the quality control of the applied coatings. This document also describes the causes of possible defects in coatings. This document is applicable to coating materials and coatings based on them; it is intended for use by manufacturers of space systems products for various surfaces of spacecraft’s and its constitutive parts (on-board systems, facilities, tools, electronic component base products) with long active lifetimes.

This document specifies general requirements for adhesive selection with the adhesive bonding process and quality assurance used in space systems. This document can be applied to different types of adhesive materials in space systems, such as launch vehicles, satellites, spacecraft and space station for the following applications: bonding, components embedding (only for space application), sealing, fixing and repairing.

This document establishes general requirements for contamination and cleanliness control that are applicable, at all tiers of supply, to the development of space systems, including ground processing facilities, ground support equipment, launch vehicles, spacecraft, payloads, and ground processing and on-orbit operations. It also provides guidelines for the establishment of a contamination and cleanliness control programme.

This document specifies the multiple measurement methods, instruments, equipment, and samples used to calculate the thermo-optical properties of thermal control materials. This document compares their features, indicates their limitations and biases, and guides the applications. This document also defines requirements for calibration and reference materials to ensure data quality. This document specifies the following test methods, including the configuration of samples and calculations. a) Solar absorptance using a spectrophotometer (αs) — Annex A. b) Solar absorptance using the comparative test method (αp) — Annex B. c) Hemispherical infrared emittance using the thermal test method (εh-t) — Annex C. d) Normal infrared emittance using an IR spectrometer (εn-s) — Annex D. e) Normal infrared emittance using ellipsoid collector optics (εn-e) — Annex E. f) Normal infrared emittance using two rotating cavities (εn-c) — Annex F.

This document defines the general requirements for atomic oxygen (AO) protective coatings that are applied on polyimide thermal control films. It also describes the different properties of coated polyimide films such as indium tin oxide (ITO), SiOx, germanium, and silicone, property measurement test methods, and selection guidelines.

This document defines the elementary thermal tests to obtain thermal properties of materials and composite materials used to manufacture space body to support the fragmentation and survivability analysis. This document does not apply to spacecraft containing nuclear power sources[1].
