Ces étalons peuvent être utilisés avec tout appareil de mesure du point de fusion; ils se préparent avec des matières premières pures. Les points de fusion sont déterminés par calorimétrie différentielle à balayage (DSC) haute précision; le système utilisé est étalonné selon l'échelle internationale de température, EIT-90.
