Soil Resistivity Measurements For Corrosion Control

Results of experiments to determine most practical soil survey procedure and best equipment are given. Correlation between soil' resistivity and corrosion is divided into five classes. Soil corrosivity maps of the area served by Southern California Gas Company were prepared. Details of several types of equipment for determining soil resistivity are given with good and bad points of each. Rules for interpretations of results are listed and the use of soil resistivity determinations indicative to types of coating are outlined.
