AB The classification, assessment, and estimation of the atmospheric corrosivity are fixedby the ISO 9223 standard. Its recent second edition introduced a new corrosivity category forextreme environments CX, and defined mathematical models that contain dose–response functionsfor normative corrosivity estimations. It is shown here that application of the ISO 9223 standardto archipelagic subtropical areas exhibits major shortcomings. Firstly, the corrosion rates of zincand copper exceed the range employed to define the CX category. Secondly, normative corrosivityestimation would require the mathematical models to be redefined introducing the time of wetnessand a new set of operation constants
