ECSS-Q-70-71A Rev.1 – Space product assurance – Data for selection of space materials and processes (18 June 2004)

This standard has been superseded by ECSS-Q-ST-70-71C (15 October 2014).


General requirements for materials and their associated processes are provided in this Standard along with the environmental requirements for materials application in space.

Annex A (informative) contains guidelines for each class of material used in the declared materials list (DML) in ECSS-Q-70 and factors to be considered for process selection. Annex B (informative) contains data sheets for materials that can be considered for use in space applications i.e. materials that were used successfully for some applications in space systems and associated equipment. Data sheets contain: property data – either frommanufacturers’ or determined by test, and comments onmaterial application in space conditions. The data sheets are grouped by their DML material class, using the class number, e.g. Class 1: Aluminium and Al-alloys; and Class 10: Adhesives, coatings and varnishes.
