Nanomaterial Risk Assessment: Refining and Validating Acceptable Variation in Nanoform Characterisers

ng Acceptable Variation in Nanoform Characterisers” The project is meant to follow up to on previous project “Nanomaterial Risk Assessment: A regulatory way forward for sameness and grouping approaches”1 contracted in 2023. In the previous contract, a framework was developed to assess the acceptable

variation within each characteriser of a Nanoform (as per Section 2.4 of Annex VI of REACH Regulation). The project aimed at exploring ways to simplify nanoforms registration process and, ultimately, its’ associated testing burden. As an o
