Document Title:Standard Test Method for Measurement of Airborne Metal and Metal Oxide Nanoparticle Surface Area Concentration in Inhalation Exposure Chambers using Krypton Gas Adsorption
url:http://compass.astm.org/EDIT/html_annot.cgi?E2864+13
Scope:This test method covers determination of surface area of airborne metal and metal oxide nanoparticles in inhalation exposure chambers for inhalation toxicology studies. Surface area may be measured by gas adsorption methods using adsorbates such as nitrogen, krypton, and argon or by ion attachment and mobility-based methods. This test method is specific to the measurement of surface area by gas adsorption by krypton gas adsorption.
Keywords:BET surface area; gas sorption analysis; inhalation exposure; krypton; metal and metal oxide nanopar
Type of Document:a. Standard
Issues Areas:Measurement and Characterizations

Goal or Need:A tiered strategy for characterization of nanoparticle properties is necessary to draw meaningful conclusions concerning dose-response relationships observed during inhalation toxicology experiments. This tiered strategy includes characterization of nanoparticles as produced (that is, measured as the bulk material sold by the supplier) and as administered (that is, measured at the point of delivery to a test subject).
Intended Stakeholders:Researchers, developers, manufacturers, and users of nanomaterials and nanotechnology-enabled products. Stakeholders from industry, government agencies, including regulatory agencies, and academia.
