Method for determining the completeness of cathodic protection of corrodible metal structure

摘要: A METHOD FOR EVALUATING THE EFFECTIVENESS OF CATHODIC PROTECTION SYSTEM IN WHICH COMPLETENESS CORRODIBLE METAL STRUCTURE EXPOSED TO CORROSIVE ENVIRONMENT IS ASCERTAINED BY MEASURING POLARITY WITH RESPECT SPECIMEN SAME PLACED AND ELECTRICALLY CONNECTED MAINTAINED ELECTROLYTIC CONTACT OUT OXYGEN. ALL AREAS ARE COMPLETELY CATHODICALLY PROTECTED WHEN EXHIBITS POTENTIAL AS TEST SPECIMEN, OR NEGATIVE SPECIMEN.
