OECD published an evaluation of the analytical methods that have been used for measuring physical-chemical properties of nanoma terials within the WPMN Testing Programme. The current evaluation was lead by the Netherlands (National Institute for Public Health and the Environment (RIVM)).

Following the evaluation of methods for physical-chemical properties, also methods for measuring endpoints related to human and environmental toxicology will be evaluated within the OECD WPMN programme.
