Understanding the IEC 61508 Functional Safety Standard The international standard, titled "Functional Safety of Electrical/Electronic/Programmable Electronic (E/E/PE) Safety-related Systems," serves as the foundational "umbrella" standard for functional safety across all industries. It provides a comprehensive framework for designing, implementing, and maintaining automatic protection systems to ensure they work correctly or fail in a predictable, safe manner.
