A comparison is made between the atmospheric corrosion of unprotected carbon steel in outdoor exposures and results from laboratory tests. The atmospheric corrosion in the outdoor exposures is expressed as a function of certain atmospheric parameters (e.g. SO 2 concentration). In the laboratory tests the atmosphere consisted of air containing known amounts of SO 2 and water vapour. The experiments were carried out in such a way that both supply and deposition of SO 2 was known. There was good agreement between the empirical formula and the results from the laboratory tests provided that the supply of SO 2 in the laboratory test was below ca. 0.5 μg · h −1 · CM −2 .
