40475 2017 eng lecture 0 -- -- -- The large European nanometrology Project NanoDefine is presented briefly with respect to the challenges of measurement of particle size distribution for complex nanoparticulate materials. The methods chosen for a tiered approach for the classification of a nanomaterial are discussed with regard to their peformance. Representative resuls on real life, complex shaped nanoparticulate materials are shown. The recently initiated VAMAS inter-laboratory comparisons to determine the reproducibility necessary for international standardisation have been also presented.
