This handbook provides guidelines to perform the worst case analysis. It applies to all electrical and electronic equipment. This worst case analysis (WCA) method can also be applied at subsystem level to justify electrical interface specifications and design margins for equipment. It applies to all project phases where electrical interface requirements are established and circuit design is carried out. The worst case analysis is generally carried out when designing the circuit. For selected circuitry, worst case analysis (WCA) can be used to validate a conceptual design approach.
NOTE: This handbook contains the informative material of the discontinued ECSS Standard ECSS-Q-30-01A. The requirements of ECSS-Q-30-01A were transferred to ECSS-Q-ST-30C.
This handbook was re-confirmed by the ECSS Technical Authority on 7 December 2022 (TA80).
This handbook supports following ECSS Standard: ECSS-Q-ST-30C – Dependability ( 6 March 2009).
