The EA (European Accreditation) is an association of national accreditation bodies in Europe which are officially recognised by their national governments. They evaluate and verify the international standards of organisations which perform evaluation services such as certification, auditing, inspections, checks and calibration.
Membership of the Deutsche Akkreditierungsstelle (DAkkS) [Germany's National Accreditation Body] in the EA means that our accreditation is recognised on a European level. This recognition on a European level reinforces our customers’ confidence in the competence, independence and impartiality of our tests.
Deutsche Akkreditierungsstelle (DAkkS) membership of the International Laboratory Accreditation Cooperation (ILAC) means that our accreditation is internationally recognised. A list of countries which are members of the ILAC and therefore mutually recognise the accreditation of member countries is available under: http://ilac.org/
