Atmospheric corrosion dose-response functions

In outdoor atmospheres dry deposition of S-pol-lutants and especially of S0 is of greatest importance. Dose response functions describing corrosion as function of SOp and time of wetness are available for some materrals as steel and zinc.

This system of atmospheric classification is now being revised to create a new approach based on dose-response functions for steel, copper, and zinc. Because the corrosion of aluminum occurs by a pitting or localized mechanism, the traditional approach of using mass loss to determine severity of attack is often misleading. Atmospheric corrosion problems with aluminum alloys are most frequently a result of metallurgical conditions rather than environmental conditions, and the behavior of aluminum may be excluded in the upcoming revision of the ISO 9223-6 documents.
