NB. The requested seal manufacturer code will be inserted as soon we have received a copy of the corresponding certificate.

NB. Only EN 16882 certified seals are allowed 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)

  • As the seal shall be replaced every two years, no seals without T logo can be found on a smart tachograph more than two years after the expiry date of self-certification (Last use of seals without T logo).

  • Seals without T logo can still be installed on analogue and digital tachographs after the expiry date set out below. The certification requirement is compulsory on the smart tachographs only.
