Lack of performance testing (validation) and demonstration are some of the key barriers for reaching general acceptance and trust in the nano-specific risk assessment and management tools. Therefore, comprehensive tool testing and demonstration were among key efforts in the EU H2020-funded project caLIBRAte (http://www.nanocalibrate.eu/home). Only tools that had good performance were considered for the caLIBRAte nano-risk governance framework and web-based nano-risk (innovation) governance portal. The work included sensitivity testing, retesting if model revisions or further developments had been made, and finally performance testing of their predictive capability using a collation of existing and three new high quality exposure measurement data sets developed in caLIBRAte.

This presentation provides an overview of the state of the art reached and lessons learned in caLIBRAte on data completeness and testing of the exposure modules in existing nano-specific control banding and risk-assessment tools. This work will be exemplified by testing exposure assessment models NanoSafer, Stoffenmanager Nano and GUIDEnano using data from different case studies.
