Railway applications - Railway applications. Communication, signalling and processing systems. Hazardous failure rates and safety integrity levels (SIL) Ingestion-build-48068 Specifications for other electroplated coatingsPD R009 001: 1999 defines the interpretation and use of Safety Integrity Levels (SIL) in safety related electronic systems for railway applications. The aim is to clarify the concept of SIL throughout the provision of: a methodology for the derivation of the safety process which is described in BS EN 50126 and based on SIL down to the elementary level in a structured and coherent manner a proposal for the correspondence between SIL and hazardous
