This report summarizes the findings of an interlaboratory study (ILS) conducted in 2009-2010 under the auspices of the Versailles Project on Advanced Materials and Standards (VAMAS) Technical Working Area (TWA) 34 (Nanoparticle Populations). The stated objective of this ILS was to assess the real world measurement precision and between-laboratory variation for determination of the surface area of an industrially-relevant metal-oxide nanomaterial in powder form. The test material, nanocrystalline titanium dioxide, also serves as the source material for production of a National Institute of Standards and Technology (NIST) Standard Reference Material (SRM 1898).
