                      Ba0.5Sr0.5Co0.8Fe0.2O3−δ has a strong application
                      potential as high-temperature gas separation membrane.
                      However, for real components the mechanical integrity of
                      this brittle perovskite ceramic will be challenged by the
                      boundary conditions of transient and stationary temperature
                      exposure. In particular, long-term failure mechanisms such
                      as static fatigue at room temperature and creep rupture at
                      operation temperature may occur. The relevance of both
                      effects is assessed. The effect of slow crack growth at room
                      temperature has been investigated using fracture stresses
                      obtained in biaxial bending under different loading rates.
                      The provided data permit to assess the fracture stresses for
                      different loading rates. Furthermore, a
                      strength–probability–time plot is derived that permits a
                      prediction of the lifetime under static loading conditions
                      and hence the long-term reliability at room temperature. The
                      creep rupture at typical operating temperatures was analysed
                      using three-point bending tests permitting a determination
                      of the failure stress in this application-related combined
                      tensile–compressive mode. The creep rupture data are
                      described by a modified Monkman–Grant relationship.},
