Abstract: This report describes the preparation and certification of a rice flour Certified Reference Material (CRM) IRMM-804. The CRM was processed and certified by the European Commission, Directorate General Joint Research Centre, Institute for Reference Materials and Measurements (IRMM), Geel, Belgium. The CRM was prepared frim rice grown on Cd enriched water. After milling the resulting powder was filled in glass bottles containing 15 g of sample. Certifcation of the CRM included testing of the homogeneity and stability of the material as well as the characterisation using an intercomparison approach. The new CRM has been certified for its content of As, Cd, Cu, Mn, Pb and Zn, while the Se mass fraction is only given as "additional material information". The main purpose of the material is to assess method performance, i.e. for checking accuracy of analytical results. As any reference material, it can also be used for control charts or validation studies.
