Why ECSS-Q-60-11A is discontinued with no "sucessor" ? Author:  Public User Date:  2009-02-05 11:28 Does anyone know the rationale behind the ECSS-Q60-11A cancelation ? The derating part have been replaced by the ECSS-Q-ST-30-11A but the End of Life parameters have been dropped with no successors when the ECSS-Q-60-11A have been Discontinued. And no new ECSS standard on End of life is foreseen… I have also seen that the end of life parameters should have been gathered in a technical memo but looking in the ECSS proceedings it appears that ESA have rejected the memo during the editorial process. So to my view there are no more ECSS/ESA consensus on End of Life parameters… Why the standard End of life parameters have been removed ? What in the End of Life data is so problematic to prevent their publication even as a non binding technical memo ? Are the data all wrong or inadequate for analysis ? Does anyone has information on the issue ? Are the parameters useable (i.e produce coherent WCA estimations) for space designs ? Many thanks
