ISO Publishes Standard on Characterization of CNT and CNF Aerosols for Inhalation Toxicity Tests

The International Organization for Standardization (ISO) recently published ISO/TR 23463:2022, “Nanotechnologies — Characterization of carbon nanotube and carbon nanofibre aerosols to be used in inhalation toxicity tests.” The standard reviews characterization of carbon nanotube (CNT) and carbon nanofiber (CNF) aerosols for inhalation exposure studies. According to the standard, the framework for material characterization for inhalation studies consists of: The standard focuses on the...
