The EU Nanosafety Cluster (NSC, www.nanosafetycluster.eu/) is a self-organising group of projects addressing various aspects of nanomaterials safety that has been operating since the start of the 7th Framework Programme . Its exact composition varies as projects finish and new ones begin, but its collaborative activities are maintained through a set of overarching working groups, including WG-F on data management which supports the projects in aspects of FAIR data including promoting the ERM. This section describes some of the current NSC projects (in no particular order) that have registered ERM identifiers, how they are using them, and projects that are actively involved with supporting community adoption of the identifier.
