Abstract 1. A METHOD FOR MEASURING LONG CELL CORROSIN CURRENT, WHICH COMPRISES: DISPOSING TWO METALLIC ELECTRODES IN SPACED RELATIONSHIP IN A CORROSIVE ELECTROLYTIC ENVIRONMENT; APPLYING ACROSS SAID ELECTRODES A FIRST D.C. POTENTIAL HAVING A VALUE OF LESS THAN 0.03 VOLT; MEASURING THE MAGNITUDE AND DIRECTION OF FIRST OBSERVED CURRENT FLOW BETWEEN SAID ELECTRODES FOR SAID FIRST APPLIED POTENTIAL; APPLYING ACROSS SAID ELECTRODES A SECOND D.C. POTENTIAL HAVING THE SAME VALUE LESS THAN 0.03 VOLT AND BEING OF OPPOSITE POLARITY TO SAID FIRST POTENTIAL; MEASURING THE MAGNITUDE AND DIRECTION OF A SECOND OBSERVED FLOW BETWEEN SAID ELECTRODES FOR SAID SECOND POTENTIAL; AND VECTORIALLY AVERAGING THE MEASURED VALUES OF SAID FIRST OBSERVED CURRENT AND SAID SECOND OBSERVED CURRENT TO OBTAIN A CURRENT VALUE CORRESPONDING TO THE LONG CELL CORROSION CURRENT.
