61508 FAQ

Frequently asked questions about IEC 61508

FAQ 1: What is the current status of 61511 Edition 2? 26/10/2017


Revision Status as of 18th October 2017

The final vote on the issue of IEC 61511.Ed2 was taken by 20 countries, and is available from the IEC Website, together with a separate corrigendum.

IEC 61511 Ed2 requires the corrigendum to be incorporated into the standard before it can be approved by CENELEC. This approval is required before it can become a BS.EN.IEC document.

However, as far as the HSE are concerned, Ed 2 with the separate corrigendum is considered “Best Practice”. Therefore, users should comply with Part 1 (the normative part).
