IEC 61508-6:2026 FDIS published — third edition with new technical annexes
Original title: Functional safety of electrical/electronic/programmable electronic safety-related systems - Part 6: Guidelines on the application of IEC 61508-2 and IEC 61508-3
IEC has released the Final Draft International Standard (FDIS) of IEC 61508-6:2026, available for purchase during its voting period (2026-10-02 to 2026-11-13); buyers also receive the Redline version upon final publication. This third edition cancels and replaces the second edition from 2010 and constitutes a technical revision. Organisations developing or certifying E/E/PE safety-related systems must review the new annexes and updated guidance to ensure their safety lifecycle processes and calculations remain aligned with the standard. Note that security requirements are explicitly out of scope — for those, the IEC 62443 series and ISO/IEC 27000 series apply.
This change concerns a paid standard. The text of the standard is not reproduced here — only the fact of the change, its date and a link to the publisher.
