Questions from last peer review • Prohibited materials (section 12. 13. 1): Pure tin (Sn), cadmium (Cd), and zinc (Zn) are not used. • Solder flux used: ROL 0 according to ECSS-Q-ST-70 -08 C 5 March 28 -29, 2011 SWEA Peer Review

PA/QA implementation (1/2) • PA and QA activities are implemented following the SWEA Performance Assurance Plan. SWEA-AP-0044 -CESR_PAP_1. 2 • Internal PA reporting is done on a monthly basis. • External PA reporting is done with project reporting. • Local PA manager is registered to ESA alert system and receives additional CNES EEE alerts. Participation to GIDEP is not possible but received alerts will be accounted for. 6 March 28 -29, 2011 SWEA Peer Review

PA/QA implementation (2/2) • Risks and critical items are managed w. r. t. ECSS-M-ST-80 C and ECSS-Q-ST-10 -04 C. • Any non-conformance will be managed according to ECSS-Q-ST-10 -09. • Documentation is managed with Baghera, a dedicated documentation management system. • Configuration control is also managed with Baghera. 7 March 28 -29, 2011 SWEA Peer Review

Reliability • Reliability is based on studies performed for SWEA-STEREO. • No possible failure propagation will be allowed in SWEA design. Safety/Hazards • Hazards identification process has been carried out. • High voltages exist but there is no exposure. • NEA (non-explosive actuators) are used but are not exposed (unintended actuation might cause contamination, enable/ disable plugs will be used) no hazard is identified 8 March 28 -29, 2011 SWEA Peer Review

EEE M&P • Both Parts Control Program and Materials and Processes Control Program are incorporated in the Performance Assurance Plan. • All requirements in chapters 11 and 12 of MAR are taken into account. 9 March 28 -29, 2011 SWEA Peer Review
