The electrical resistance technique described here has been developed for practical application to corrosion tests of industrial laboratories. The technique can detect corrosion losses to a fraction of a microinch, does not require removal of corrosion products or other deposits and can be adapted to virtually all corrosive media and conditions. The main usefulness of the method is in establishing the relative corrosivities of media which are closely alike. Several typical applications are given: 1) the determination of the relative corrosivities of crude oils at refinery temperatures, 2) the indentification of the source of the corrosive components responsible for the attack in a vis-breaking unit charging a complex feed mixture, 3) the determination of the corrosivity of sulfuric acid sludges, 4) a quantative assessment of oil-soluble rust inhibitors, and 5) the determination of the corrosivity—to lead—of oxidized lubricating oils as a function of the degree of oxidation of the oils.

ANDREW DRAVNIEKS—Senior Project Engineer in the Engineering Research Department at Standard Oil Company (Indiana) he holds a ChE degree from University of Latvia)1938), did advanced work there and at Marburg University, Germany, and received a PhD from Illinois Institute of Technology in 1949. He has been instructor at the University of Latvia and technical director of a paint firm in that country as well as research associate with Illinois Institute of Technology. His work centers on paint technology, polarography, surface chemistry and the kinetics of corrosion processes, especially at elevated temperatures.
HORACE A. CATALDI—When the work reported in the paper included in this symposium was done he was Assistant Project Engineer in the Engineering Research Dept., Standard Oil Company (Indiana) and engaged full time in corrosion research. He joined Standard Oil in 1950. He is now in the Materials and Processes Laboratory, Large Steam Generator Dept., General Electric Company, Schenectady, N. Y., working on high temperature corrosion. He has a BS in chemical engineering from College of the City of New York (1940) and a PhD in chemical engineering from the University of Illinois in 1949. He was employed as a physicist by the Navy Department during the war and worked as a physical chemist and assistant department supervisor in electronics at Oak Ridge.
