Abstract

This work introduces the European Metrology Research Project on the SI traceability of electrolytic conductivity measurements in bioethanol. As a first step to this aim secondary conductivity measurements have been performed to characterise reproducibility, stability, measurement uncertainty and the significance of the measurement results. The standard measurement uncertainty is in the order of 0.3 %. Two samples from different sources show significantly different conductivity values. The results indicate that conductivity is an appropriate quality indicator for bioethanol.
