Why it matters
IEC has released the Final Draft International Standard (FDIS) for IEC 61508-3:2026, the third edition covering software requirements for functional safety of E/E/PE safety-related systems, available for purchase during its voting period from 2026-10-02 to 2026-11-13. This edition is a technical revision that cancels and replaces the second edition (2010). Organisations developing or certifying E/E/PE safety-related software must prepare to align with updated systematic capability requirements and clarified formal methods guidance. Purchasers of the FDIS will automatically receive the Redline version of the final publication upon release.
