Abstract

The factors influencing the results of several kinds of tests for the corrosion of metals in soils are discussed. Laboratory and field tests of soil corrosion are described in detail. An equation is presented in which the average depth of the deepest pits on corroded surfaces of ferrous metals is related to: (1) the corrosiveness of the soil; (2) the area exposed; and (3) the duration of exposure. The constants in this equation are given for the soils in the Bureau of Standards soil corrosion investigation. A procedure for determining the corrosiveness of soils with respect to iron and steel is described.
