IEC TR 62368-2:2025 identifies the purpose and applicability of IEC 62368-1:2023 and the exclusions from the scope. The scope excludes requirements for functional safety. Functional safety is addressed in IEC 61508-1. Because the scope includes computers that can control safety systems, functional safety requirements would necessarily include requirements for computer processes and software. The…
