Following their meeting in June 2014, the OECD Working Party on Manufactured Nanomaterials (WPMN) has released a summary report on the applicability of existing OECD Test Guidelines with regards to physical-chemical properties, which are relevant for the safety and regulatory decision-making of nanoform substances. The document also includes several recommendations for the further refinement of test methods and characterisation of nanomaterials.

A second report released by the WPMN discusses the responses to, and findings from, a survey on the concepts of grouping, equivalence and read-across, based on the physical-chemical properties of nanomaterials. The OECD will collate the different approaches of its member states and work towards harmonised guidance on the subject.
