The International Organization for Standardization (ISO) has issued new guidance pertaining to the characterization of nanoscale material before conducting health-related testing on the material. Titled “Nanotechnologies—Guidance on Physico-Chemical Characterization of Engineered Nanoscale Materials for Toxicologic Assessment,” ISO /TR 13014:2012 seeks to assist in planning, identifying and understanding the relevant physical and chemical characteristics of nano-sized objects before subjecting them to toxicological tests.  

ISO describes “nanoscale” as relating to materials of sizes approximately 1 to 100 nanometers. The work called for by the ISO report is intended to help scientists understand what the material looks like, what it is made of, and how it interacts with the surrounding environment, in the context of toxicological testing. Further information is posted on the ISO Website.
