IEC 61508-1:2026 FDIS published — third edition of functional safety general requirements
Original title: Functional safety of electrical/electronic/programmable electronic safety-related systems - Part 1: General requirements
IEC has released the Final Draft International Standard (FDIS) for IEC 61508-1:2026, the third edition of the general requirements standard for functional safety of electrical/electronic/programmable electronic (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 of the 2010 second edition and introduces changes affecting the scope and structure of the standard. Organisations developing or certifying E/E/PE safety-related systems will need to review updated requirements covering AI, human factors, and the coordination boundary with cybersecurity. Purchasers of the FDIS automatically receive the Redline version of the final publication upon its official release.
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.
