“…Due to the low test duration and costs, highly accelerated lab tests with a maximum duration of 24 h are the most frequently utilized tests for IGC investigations in academic research as well as in the European automotive industry . In order to trigger corrosion, highly aggressive solutions are used, which often contain high amounts of NaCl and hydrochloric acid.…”

Two highly accelerated lab tests, ISO 11846 Method B and PV1113, three cyclic tests, VDA621‐415 (also known as ISO11997 Cycle B), VDA233‐102, and ASTM G85 Annex 2 as well as an accelerated urban outdoor exposure were investigated and compared with respect to their suitability for the evaluation of the IGC susceptibility of bare 6000 aluminum alloys. AA6014 and AA6016, each tested in a low and a high Cu containing variant, suffered, predominantly, intergranular corrosion (IGC) when tested under ISO 11846 and PV1113 conditions. The results obtained by ISO11846 were systematically higher compared to those measured using PV1113. VDA621‐415 (ISO11997 Cycle B) and VDA233‐102 caused only slight localized corrosion, which occurred as IGC, too; however, the density of attack was low. ASTM G85 A2 was the only test that predominantly caused pitting corrosion to occur on all materials.
