European Foreword
This document (EN 16602-70-17:2020) has been prepared by Technical Committee CEN/CLC/TC 5
“Space”, the secretariat of which is held by DIN (Germany).
This document (EN 16602-70-17:2020) originates from ECSS-Q-ST-70-17C.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by October 2020, and conflicting national standards shall
be withdrawn at the latest by October 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been developed to cover specifically space systems and will therefore have
precedence over any EN covering the same scope but with a wider domain of applicability (e.g.:
aerospace).
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implemen
