AbstractAlthough the corrosion of metals during outdoor exposure correlates with the time-of-wetness due to both condensation and precipitation, a better correlation would be obtained with time-of-wetness caused by condensed moisture alone, because it contains a greater amount of corrosive SO[2] than precipitated moisture. A method for determining the time-of- wetness produced solely by condensed moisture on metals was developed and tested. The condensation time-of-wetness from November 1981 to October 1982, at Ottawa, was 16% of the total exposure time and greater than that due to precipitation by a factor of 2.
