DANSK DSF/IEC 62278-2 ED1 PDF

This part 2 of IEC 62278 • considers the safety-related generic aspects of the RAMS life cycle; • defines methods and tools which are independent of the actual technology of the systems and subsystems; • provides the user of the document with: – the understanding of the system approach to safety which is a key concept of IEC 62278; – methods to derive the safety requirements and their safety integrity requirements for the system and to apportion them to the subsystems; – methods to derive the safety integrity levels (SIL) for the safety-related electronic functions. NOTE – This document does not allow the allocation of safety integrity levels to non-electronic functions.
