Atmospheric corrosion can seriously affect the performance of steel structures over long periods of time. Standards and codes represent the general guidelines and suggest general protection techniques to prevent structures from corrosion damage. The EN ISO 12944 criteria and guidelines help to select the right paint system for each project. The basis system of atmospheric corrosivity classification was specified by EN ISO 9223 and this system is implemented into other standards for protective coating choice (paint coating, metallic coating, duplex system, etc.). The corrosivity category is also important for accelerated testing of chosen protective systems – regime and duration of test. Due to changing and varying environmental situation in Europe the actual data is necessary to use. The specific microclimates are presented too.
