ECSS-Q-60-11A – Derating and end-of-life parameter drifts — EEE components (7 September 2004)

ECSS-Q-30-11A (24 April 2004) cancels and replaces the derating requirements applicable to electronic, electrical and electromechanical components of this standard.


This Standard applies to all parties involved at all levels in the realization of space segment hardware and its interfaces.

The objective of this Standard is to provide customers with a guaranteed performance and reliability up to the equipment end-of-life. To this end, the following are specified:

  • Load ratios or limits to reduce stress applied to components;
  • Estimation of end-of-life drifts due to ageing;
  • Application rules and recommendations.
