scope:
This report defines the interpretation and use of Safety Integrity levels in safety-related electronic systems for railway applications. The aim is to clarify the concept of Safety Integrity Levels (SIL) through the provision of: a methodology for the derivation of the safety process which is described in prEN 50126 standard and based on SIL down to the elementary level in a structured and coherent manner; a proposal for the correspondence between SIL and hazardous failure rates.
