Space engineering - Adhesive bonding for spacecraft and launcher applications

The scope of the document addresses the generic verification for all types of adhesive bonding for space applications including evaluation phases. It specifies all aspects of the adhesive bonding lifetime such as assembly, integration and testing, on-ground acceptance testing, storage, transport, pre-launch, launch and in-flight environments.
This standard does not cover requirements for:
-   adhesive bonding used in EEE mounting on printed circuit boards (ECSS-Q-ST-70-61)
-   adhesive bonding used in hybrid manufacturing (ESCC 2566000)
-   adhesive bonding for cover-glass on solar cell assemblies (ECSS-E-ST-20-08)
-   design of adhesive joint
-   long term storage and long term storage sample testing
-   performance of adhesive bond
-   functional properties of adhesive joint
•   co-curing processes
This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00.

Ingénierie spatiale - Collage adhésif pour les applications d'engins spatiaux et lanceurs

Le présent document couvre la vérification générique de tous les types de collages adhésifs destinés à des applications spatiales, y compris les phases d'évaluation. La présente norme couvre tous les aspects du cycle de vie du collage adhésif, tels que l'assemblage, l'intégration et les essais, les essais de recette au sol, le stockage, le transport, le pré-lancement, le lancement et les environnements en vol.
La présente norme ne couvre pas les exigences relatives :
- au collage adhésif utilisé dans un montage EEE sur des circuits imprimés (pour ce sujet, voir l’ECSS-Q-ST-70-61) ;
- au collage adhésif utilisé dans la fabrication d'hybrides (pour ce sujet, voir l’ESCC 2566000) ;
- au collage adhésif utilisé pour le verre de protection d'ensembles de cellules solaires (pour ce sujet, voir l’ECSS-E-ST-20-08) ;
- à la conception de joints adhésifs (pour ce sujet, voir l’ECSS-E-ST-32) ;
- au stockage à long terme et aux essais sur échantillons de stockage à long terme ;
- aux performances des collages adhésifs ;
- aux propriétés fonctionnelles des joints adhésifs ;
- aux processus de copolymérisation ;
- à la prédiction de la durée de vie, ni au sol (humidité) ni en orbite (cyclage thermique).
La présente norme peut être adaptée aux caractéristiques et contraintes spécifiques d’un projet spatial, conformément à l’ECSS-S-ST-00.
