Take a Virtual tour through our processing hall to see how we turn the raw material into the candidate reference materials. After this first step, the homogeneity and stability studies and the characterisation study can start. These studies together form the basis of the assigned values and their uncertainties, resulting finally in the reference materials available on this catalogue.
