RWTÜV GmbH together with TÜV NORD e.V. and TÜV Hannover/Sachsen-Anhalt e.V. hold the shares in TÜV NORD AG. This equity relationship stems from 2004, when the traditional testing and inspection business of RWTÜV was merged with the operating service companies of TÜV NORD e.V., Hamburg and TÜV Hannover/Sachsen-Anhalt e.V.
