The NanoHarmony and NANOMET projects had their first face-to-face joint workshop on OECD Test Guideline (TG) Development for nanomaterials back-to-back with the WPMN at the OECD Conference Centre in Paris on 29-30 June.
During the workshop, challenges and best practice approaches for the TG development were discussed. A special focus was set on the use of TGs in regulation from an international point of view. NanoHarmony and NANOMET informed participants about the different steps of the TG development process, potential process improvements and ongoing TG developments for nanomaterials. The open discussions were used to collect input from stakeholders, both on the OECD process and on current OECD projects towards developments of TGs and GDs.
