Book excerpt: Electrochemical potentiokinetic reactivation (EPR) tests can be used to measure quantitatively the sensitization of Type 304 stainless steel. The single loop (SL) and double loop (DL) EPR techniques were compared as non-destructive methods for determining sensitization under both laboratory and simulated field environments. Measurements were performed on specimens heat-treated to produce levels of sensitization from no sensitization to heavy sensitization. At temperatures of 22°C and 30°C testing with standard laboratory and portable field apparatus, both EPR techniques were capable of distinguishing sensitization levels at the range spanning those characterized as being non-susceptible and susceptible to intergranular stress corrosion cracking (IGSCC). Through correlations developed for the test data, it is possible to translate field results to the standard laboratory test conditions. This was demonstrated for the SL test through measurements performed on a pipe specimen containing IGSCC. 12 refs., 12 figs., 2 tabs.
