IEC 61508 addresses functional safety for electric, electronic and programmable systems used in energy, transportation or industrial applications. It covers system design, hardware design and software design as well as the core processes that underpin each of these processes, including configuration management, quality assurance and functional safety.
IEC 61508 is composed of seven parts:
- IEC 61508-1, General requirements
- IEC 61508-2, Requirements for E/E/PE safety-related systems
- IEC 61508-3, Software requirements
- IEC 61508-4, Definitions and abbreviations
- IEC 61508-5, Examples and methods for the determination of safety integrity levels
- IEC 61508-6, Guidelines on the application of IEC 61508-2 and IEC 61508-3
- IEC 61508-7, Overview of techniques and measures
