IEC 61511-1: Edition 3 is targeted for release in 2023, with the first Committee Draft due for release in early 2021. The presentation will describe the areas of focus for the development of the new edition and the background to the proposed changes.

Of course it is possible that the proposals will not be approved by the National Committees when they vote on the changes in later in 2021, but the direction that the developments are taking is clear.

This presentation will look at the main changes which are, to some extent, still being debated.
