IEC 61508-5:2026 FDIS published — examples of methods for determining safety integrity levels
Original title: Functional safety of electrical/electronic/programmable electronic safety-related systems - Part 5: Examples of methods for the determination of safety integrity levels
IEC has released the Final Draft International Standard (FDIS) for IEC 61508-5:2026, available for purchase during its voting period from 2 October to 13 November 2026. The document provides guidance and illustrative methods for determining safety integrity levels (SILs) for electrical, electronic, and programmable electronic safety-related systems, covering underlying risk concepts and criteria for method selection. Purchasers of the FDIS will automatically receive the Redline version of the final publication upon its release. Organizations relying on IEC 61508-5 for SIL determination should note this is a pre-release; the final standard supersedes prior guidance once officially published.
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.
