Note: Trials are conducted in accordance with the standards listed or methods derived from these internal standards.

Equipements:

As part of project / contract research and development provides the means CODEM semi-industrial and industrial manufacturing and product characterization (mixers, presses, ovens...).

Investments made to acquire these resources have been made with the support of the Regional Council of Picardie.
