Standards and technical specifications related to parts and materials for the needs of space or for the common needs of space and aeronautics are being processed through the AeroSpace and Defence Industries Association of Europe (ASD-STAN).
Cooperation with ASD-STAN goes back to 1973 when a protocol between the two organisations was signed. ASD-STAN has been recognised as an Associated Body of CEN in 1986, and is responsible for the technical aspects of standards defining products, materials, test methods and procedures for the construction, maintenance and use of aircraft and space vehicles including their propulsion units, equipment and electric equipment.
ASD-STAN develops specifications for aerospace applications, mainly in the field of engineering materials and components and submits the drafts to CEN for adoption as European Standards.
To date, the technical content of over 1600 European Standards originates in ASD-STAN.
