During the course of a long‐term corrosion investigation, it was necessary to design an apparatus capable of testing specimens under conditions as closely related as possible to those of actual service in a closed system. Speller demonstrated that the rate of corrosion in a closed system increases steadily with an increase in temperature, but in a system open to the atmosphere, a maximum rate is reached at approximately 80°C. The test presented in this paper is described as rigorous, and uses of the only apparatus of this type. Test apparatus, operating conditions, and results are discussed, with study conclusions indicating that the apparatus proved satisfactory in testing the corrosion of steel specimens in a closed system using municipal waters. The results of tests carried out over a period of several months demonstrated that the composition of the corrosion medium, and not the composition of the steel samples, is the important factor.
