DESCRIPTION

EN ISO 12732


EN ISO 12732 Corrosion of metals and alloys - Electrochemical potentiokinetic reactivation measurement using the double loop method (based on Čihal's method) - ISO 12732:2006 specifies the method for measuring the degree of sensitization (DOS) in stainless steel and nickel-based alloys using the Double Loop Electrochemical Potentiokinetic Reactivation (DL-EPR) test (based on Cihal's method). The method may be used for the quantitative assessment of deleterious thermal effects resulting in the formation of alloy-element-depleted zones at grain boundaries or in the matrix. However, attention should be paid when testing heat-affected weld zones, due to possible non-uniform distribution of sensitized zones along the fusion lines. The results of the test can be used as an index to identify the potential susceptibility of stainless steel and nickel-based alloys to intergranular corrosion, pitting corrosion, and intergranular-stress corrosion cracking, but prediction of these corrosion modes depends on complementary specific testing. ISO 12732:2006 describes the general methodology and gives examples of suitable test exposure conditions for specific alloys.
