From March 1, 2022, workshop managers and truck manufacturers may only purchase tachograph seals from a seal manufacturer that holds an EN 16882 certification. This certificate is issued to producers after several tests by an accredited laboratory in accordance with the European standard EN 16882. 

The “T” engraved on our seals has been authorised by the European Commission as proof of certification. Only seals certified according to EN 16882 are entitled to bear the T logo. Workshops are not allowed to place a seal without T logo on smart tachographs after the expiry date of self-certification (Last use of seals without T logo) anymore. In order to identify our certified tachographs, we have obtained the abbreviation „UN“, which can be found on every Unisto Tacho Seal.
