Experimental data describing the degradation of carbon steel were collected over 3 years from 74 test sites distributed along the seven islands that form the Canary Islands (Spain). The main parameters introduced in the models were the deposition rates for chloride and sulphur dioxide, time of wetness and exposure time. A set of qualitative variables was introduced to account for the variations occurring at different sites at early exposures as to characterize their initial local characteristics. The impact of the new parameters was evaluated from the models, and good fitting correlations between experimental and estimated data have been achieved SN 978-989-8601-31-5 YR 2013 FD 2013 LK http://riull.ull.es/xmlui/handle/915/19151 UL http://riull.ull.es/xmlui/handle/915/19151 LA en DS Repositorio institucional de la Universidad de La Laguna RD 22-nov-2024
