After the Official Journal harmonised EN 60601-1 on 17 June 2026, I later wrote up an overview: what changed, the nine-year wait, what to cite, and the EC REP to EU REP switch riding alongside it. Then the comments started, and the good ones went straight past the headline. This is the deeper cut.
This post assumes you already know that EN 60601-1:2006/A13:2024 landed at entry No. 65 and that A13 carries Annex ZZ. From here I want to answer the questions my readers actually asked. I have deliberately not repeated much of what is already in the LinkedIn article, which covers the background, the full decision, and several points I do not revisit here, so it is worth reading alongside this.
