This standard (EN 16602-70-71:2016) originates from ECSS-Q-ST-70-71C. This European Standard shall be given the status of a national standard, either by publication of an
18、identical text or by endorsement, at the latest by February 2017, and conflicting national standards shall be withdrawn at the latest by February 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not b

This Standard covers the following: selection criteria and rules; utilization criteria and
23、 rules. The provisions of this Standard apply to all actors involved at all levels in the production of space systems. These can include manned and unmanned spacecraft, launchers, satellites, payloads, experiments, electrical ground support equipment, mechanical ground support equipment, and their c
24、orresponding organizations. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.
