Both field exposed bare and coated panels are withdrawn at definite interval for conducting few confirmatory tests. To evaluate correlation, accelerated laboratory tests are conducted on unexposed bare and coated panels. The tests are AC/DC impedance, EIS, SEM and XRD, Raman spectroscopy, salt spray, and humidity tests.
