Popis:	This paper is designed to divulge some tests found in books, articles and international technical standards, by means of which it is possible to evaluate the performance of reference electrode widely used in potentiometric and voltammetric methods. The reference potential (Eref), junction resistance (Rj), the ability of keeping up the potential when current is flowing (polarizability), and of generating junction potentials (Ej) are applied to some commercial electrodes. The results obtained are amply discussed and some corrective procedures are suggested when the electrode fails.
