Field exposure studies under sheltered and unsheltered conditions at different test sites in northern and eastern Germany

  • A series of field exposure tests according to ISO 9223 and 9226 was carried out at different locations to determine the corrosivity of different test sites throughout northern and eastern Germany. Standard test specimens of steel, zinc, copper and aluminium were exposed to rural, city and maritime atmosphere at test sites of the Federal Institute for Materials Research and Testing. Test sites at city atmosphere comprised exposure on a rooftop, next to a highly frequented road and directly at a motorway. Exposure under maritime conditions was carried out at Heligoland in the North Sea and at the North Sea coastline on Sylt. The specimens were stored under sheltered and unsheltered conditions on each test site, respectively. Corrosion rates after the first year of field exposure were determined and used for the classification of the atmospheres and the test sites regarding the corrosivity. The presentation will show the results of the systematic study.

Corrosion rates after the first year of field exposure were determined and used for the classification of the atmospheres and the test sites regarding the corrosivity. The presentation will show the results of the systematic study. First year corrosion rates for steel, zinc, copper and aluminium will be presented and discussed with respect to the type of material, the atmospheric conditions and the time of wetness at the test sites. In addition, the difference between sheltered and unsheltered conditions will be discussed.zeige mehrzeige weniger
