This document describes the preparation of polydisperse spherical particles based on a picket fence of quasi-monodisperse reference materials, the characterization of its monodisperse components with acceptable uncertainty and the estimation of the uncertainty of the mixture of these particles. This type of material is normally suitable for all particle characterization methods within the appropriate limits of the techniques. An example of using these reference materials in a reliability calculation for a mass-based cumulative size distribution is provided.

This document limits itself to the technical specificities of preparation beyond the general requirements for certified and non-certified reference materials as described in ISO Guide 30 , ISO Guide 31 , ISO Guide 35 and ISO 17034 .
