That's CEN, not EU
CEN is officially recognized as a European standards body by the European Union, European Free Trade Association and the United Kingdom; the other official European standards bodies are the European Committee for Electrotechnical Standardization (CENELEC) and the European Telecommunications Standards Institute (ETSI).
Doesn't have to, just have to embrace and enforce its standards.
(Btw, I'm from the EU, thanks for the lecture on Europe vs the EU, who would have thought!).
