Correlation between laboratory test and field tests for filiform corrosion of painted aluminum alloy sheets for automobile was investigated by conducting 6 kinds of laboratory tests with different pH, dry-wet condition, etc., and 2 sites of outdoor exposure tests, and vehicle test. It was found that susceptibility to filiform corrosion in the laboratory tests increased with the decrease of pH and/or the increase of repetition rate of wet/dry cycle, and that correlation between outdoor exposure tests and vehicle test was low. In conclusion, the laboratory tests with relatively low wet ratio(70%)correlated well with the outdoor exposure tests, and the tests with relatively high wet ratio(95%)correlated with the vehicle test.
