The European Commission's Joint Research Centre has developed the world's first certified nanoparticle reference material based on industry-sourced nanoparticles. This new material will help ensure the comparability of measurements worldwide, thereby facilitating trade, ensuring compliance with legislation and enhancing innovation.
The material (ERM-FD100) consists of silica nanoparticles of a nominal diameter of 20 nanometers (nm). Silica nanoparticles are amongst the most widely used nanoparticles at the moment in products such as polish, whiteners and dispersants.
This material provides the basis for reliable hazard assessments and to check that nanomaterials conform to the internationally accepted definition, as laid down in the respective ISO (International Organisation for Standardisation) technical specification. It will enable producers of nanoparticles to monitor production quality over time against a stable reference point, and to assess the impact of process improvements.
Particle size was measured in collaboration with 33 laboratories from 11 different countries in Europe, America and Asia
