ECSS-E-ST-20-07C - Rev. 2 - Electromagnetic compatibility

Aug 31, 2026

Standard for electromagnetic compatibility management, engineering and product assurance in space projects, specifying outcomes in terms of “shall be accomplished” rather than prescribing how work is organized. It defines requirements prepared by the ECSS Working Group and reviewed and approved by ECSS authorities, supporting consistent standards evolution across agencies and industry partners. A legal disclaimer limits any express or implied warranties and excludes liability for damages related to use of the standard.

DOCPROPERTY "ECSS Discipline" \* MERGEFORMAT Space engineering ECSS Secretariat ESA-ESTEC Requirements & Standards Section Noordwijk, The Netherlands SUBJECT \* FirstCap \* MERGEFORMAT Electromagnetic compatibility Foreword This Standard is one of the series of ECSS Standards intended to be applied together for the management, engineering, and product assurance and sustainability in space projects and applications. ECSS is a cooperative effort of the European Space Agency, national space agencies and European industry associations for the purpose of developing and maintaining common standards. Requirements in this Standard are defined in terms of what shall be accomplished, rather than in terms of how to organize and perform the necessary work. This allows existing organizational structures and methods to be applied where they are effective, and for the structures and methods to evolve as necessary without rewriting the standards. This Standard has been prepared by the DOCPROPERTY "ECSS Working Group" \* MERGEFORMAT ECSS-E-ST-20-07C Rev. 2 Working Group, reviewed by the ECSS Executive Secretariat and approved by the ECSS Technical Authority.
