Particle size analysis. Small angle X-ray scattering method Ingestion-build-224916 BS EN 15558:2009 supersedes CEN/TS1 Scope This Technical Specification specifies the method for determining particle size distribution of ultra fine powders by the small angle X ray scattering technique. It is applicable to particle sizes ranging from 1 nm to 300 nm. In the data analysis, it is assumed that particles are isotropic and spherically shaped. The method described in this Technical Specification is also applicable to particle suspensions. This Technical Specification does
