March 28-29, 2011 SWEA Peer Review Questions from last peer review Prohibited materials (section ): Pure tin (Sn), cadmium (Cd), and zinc (Zn) are not used. Solder flux used: ROL0 according to ECSS-Q-ST-70-08C 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-80C and ECSS-Q-ST-10-04C. Any non-conformance will be managed according to ECSS-Q-ST 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 Safety/Hazards Reliability is based on studies performed for SWEA-STEREO. No possible failure propagation will be allowed in SWEA design. 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
