Why it matters
IEC has released the Final Draft International Standard (FDIS) of IEC 61508-2:2026, covering requirements for electrical/electronic/programmable electronic (E/E/PE) safety-related systems, available for purchase during the voting period from 2026-10-02 to 2026-11-13. Purchasers of the FDIS will automatically receive the Redline version of the final publication upon release. The new edition introduces several significant technical changes that affect how practitioners structure safety integrity assessments and where they look for semiconductor-specific guidance. Compliance teams should note that security requirements remain out of normative scope — the standard points to IEC 62443 and ISO/IEC 27000 for security, and to IEC TR 63069 for safety-security coordination.
