| Summary: |
This webpage of ASTM International lists all nanotechnology standards that ASTM has developed. The standards fall into one of three categories: Informatics and Terminology; Environment, Health, and Safety; and Characterization: Physical, Chemical, and Toxicological Properties. ASTM currently has standards which define nanotechnology terminology and specify how to handle unbound engineered nanoscale particles in occupational settings. For characterization, there are also standards which define how to measure particle size distribution of nanomaterials in suspension, how to analyze hemolytic properties of nanoparticles, how to evaluate the effect of nanoparticulate materials on the formation of mouse granulocyte-macrophage colonies, how to evaluate cytotoxicity of nanoparticulate materials in porcine kidney cells and human hepatocarcinoma cells, and how to calculate mean sizes and standard deviations of particle size distributions. |
