24、 Foreword This document (EN 16603-35-01:2014) has been prepared by Technical Committee CEN/CLC/TC 5 “Space”, the secretariat of which is held by DIN. This standard (EN 16603-35-01:2014) originates from ECSS-E-ST-35-01C. This European Standard shall be given the status of a national standard, either
25、by publication of an identical text or by endorsement, at the latest by March 2015, and conflicting national standards shall be withdrawn at the latest by March 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENE
26、LEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14607-5-1:2004.
