ECSS-Q-ST-30-11C (REV. 1), SPACE PRODUCT ASSURANCE: DERATING - ELECTRICAL, ELECTROMECHANICAL, AND ELECTRONIC (EEE) COMPONENTS (04-OCT-2011)

ECSS-Q-ST-30-11C (REV. 1), SPACE PRODUCT ASSURANCE: DERATING - ELECTRICAL, ELECTROMECHANICAL, AND ELECTRONIC (EEE) COMPONENTS (04-OCT-2011)., This Standard specifies derating requirements applicable to electronic, electrical and electromechanical (EEE) components. Derating is a long standing practice applied to components used on spacecrafts. Benefits of this practice are now proven, but for competitiveness reasons, it becomes necessary to find an optimized reliability. Too high a derating can lead to over‐design, over‐cost and over‐sizing of components, the direct consequence being excess volume and weight. The aim is to obtain reliable and high performance equipment without over‐sizing of the components. For this reason and if possible, this Standard provides derating requirements depending on mission duration and mean temperature, taking into account demonstrated limits of component capabilities.
