Definitions used in the context of this Guideline can be found in Annex 1 and in GD 39. This Test Guideline is not specifically intended for the testing of nanomaterials. Find out how Test Guidelines are developed through the OECD, with case studies from the Test Guidelines being supported through the projects for expansion into nanomaterials.
