European Reference Materials or ERM are certified reference materials of high quality and reliability produced by members of the European Reference Materials consortium in the European Union .
European Reference Materials are a tool for improving the confidence in, and the mutual recognition of test results and certificates in the European market. The Certified Reference Materials (CRMs) comply with high metrological requirements, ensuring traceability of measurements results, and are the end-point of the traceability chain, thus being primary standards in chemistry.
The European Reference Materials concept is a collaboration between:
- The Institute for Reference Materials and Measurements (IRMM) of the European Commission's Directorate General Joint Research Centre, Geel, Belgium
- The Bundesanstalt für Materialforschung und -prüfung (BAM), Germany
- LGC, United Kingdom

O mystical monster marine?”

“I am more and more convinced that, with reference to any public question, it is more important to know what the country thinks of it than what the city thinks. The city does not think much.”
—Henry David Thoreau (1817–1862)
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
