Based on the results achieved in the field of coulometry, Panta Tutundžić presented to the International Union for Pure and Applied Chemistry (IUPAC) in 1956 in Lisbon a proposal to introduce the pendant, a unit of electricity, as a universal standard in analytical chemistry. At the world exhibition in Brussels in 1958, in the International Pavilion of Science, the exhibit of Pante Tutundzic "Coulomb as a universal substance in analytical chemistry" was exhibited.
