There are no specific criteria of affiliation to an ERN. It is a competence of Member States to designate their potential affiliated partners.

According to the Board of Member States: ERN applicants will be encouraged to liaise with National authorities, where appropriate, to identify a list of potential affiliated partners, for collaboration with the network from the outset.
