Fact Sheet VectorCAST for EN 50128
The European Standard EN 50128 (EN 50128: “Software for railway control and protection systems,” March 2001) provides a process framework and a procedural model for the development and test of safety critical electronic systems in railway systems. It is a derivative of the International Electronic Commission document 61508 (IEC 61508) adapted for the challenges met in railway systems.
EN 50128 takes into account the five software integrity levels (SIL) that range from the very critical (SIL-4), such as safety signaling to the non-critical, such as management information systems (SIL-0).
