Conformity Assessment Body

Competent conformity assessment services for manufacturers as a basis for the access to the national, european or international market


PTB's certification body performs conformity assessments within the scope of different certification schemes.

Quality system

The certification body operates a quality system which - as an integral part of the quality system of PTB - meets the requirements for certification bodies for products, processes and services in accordance with ISO/IEC 17065. PTB thus meets - in connection with the compliance of the requirements of ISO/IEC 17025 by the Divisions in which the product tests are performed on which the conformity assessments are based - the requirements of the European Union for Notified Bodies.
