RT info:eu-repo/semantics/article T1 Shortcomings of international Standard ISO 9223 for the classification, determination and estimation of atmosphere corrosivities in subtropical archipelagic conditions: The case of the Canary Islands (Spain) A1 Souto, Ricardo Manuel A1 Santana, Juan José A1 Ramos, Alejandro A1 Rodríguez-González, Alejandro A1 Vasconcelos, H. Cristina A1 Mena, Vicente A1 Fernández Pérez, Bibiana María K1 atmospheric corrosion K1 ISO 9223 K1 corrosivity categories K1 predictive models K1 archipelagic regions K1 Canary Islands 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 YR 2019 FD 2019 LK http://riull.ull.es/xmlui/handle/915/18953 UL http://riull.ull.es/xmlui/handle/915/18953 LA en DS Repositorio institucional de la Universidad de La Laguna RD 12-dic-2024
