About the council

Founded in early 2016, the council is a registered union of Accredited Conformity Assessment Bodies (ACABs) on the one hand, of any Interested Parties (IP) on the other hand.

Its aim is to harmonize the application of the conformity assessment requirements derived from the eIDAS regulation (*), first within its members, but also with regard to the broader conformity assessment community and in partnership with the main stakeholders of the area, such as ETSI, ENISA, CA/Browser Forum, CEN, FESA/ECATS, ...


It provides many opportunities:

  • to encourage, promote and enable the exchange of information between the member organizations;
  • to encourage and support the regular occurrence of conferences and other events and projects, addressing issues of common concern to all member associations;
  • to produce and/or endorse policy statements and position papers on key issues such as technical and organizational standards and regulations which are of interest to third parties.


Furthermore, we aim to propose a common set of document templates to be used by member CABs for ETSI as well as for eIDAS audits (audit attestation letter, audit certificate, audit report), providing clarity on audit and report related aspects.


(*) eIDAS regulation (EU) N° 910/2014 of the European Parliament and of the European Council of the 23 rd of July 2014 on electronic identification and trust services for electronic transactions in the internal market, repealing Directive 1999/93/EC and Regulation (EU) 2024/1183 of the European Parliament and of the Council of 11 April 2024 amending Regulation (EU) No 910/2014 as regards establishing the European Digital Identity Framework.
