Se presentan los resultados de la medicion de la corrosion metalica de: acero, acero galvanizado, cobre y aluminio en el caso de la corrosion en ambientes exteriores, y de acero, estano y cobre en ambientes interiores. Las estaciones de ensayo se ubican en las ciudades de Quito y Esmeraldas, los ensayos se realizaron utilizando las normas ISO y ASTM. Los resultados muestran que los niveles de corrosividad son mas altos en la ciudad de Esmeraldas (particularmente para la corrosion en ambientes interiores) debido a la presencia de fuentes de contaminacion atmosferica, como son la refineria y la termoelectrica situadas en esa zona, la influencia marina resulta poco significativa debido a la distancia y ubicacion de la estacion de ensayo en la ciudad de Esmeraldas. This work reports the assessments of corrosion measurement on steel, galvanized steel, copper and aluminum in the case of outdoor atmospheric corrosion, and steel, tin and copper indoor atmospheric corrosion. The test stations are located in the cities of Quito and Esmeraldas. Additionally, assays were performed using ISO and ASTM standards. Main results show that corrosivity levels are higher in Esmeraldas (particularly indoors corrosion) due to the presence of pollution sources such as refinery and the thermoelectric stations located in that area. Furthermore, in Esmeraldas the influence of the sea is not significant due to the distance and location of the test stations.
