This article responds to the article “Corrosion Behavior of Ductile Cast‐Iron Pipe in Soil Environments” by W.F. Gerhold, which appeared in the December 1976 issue of JOURNAL AWWA, p. 674. The inadequacies of the testing procedures used by the National Bureau of Standards in its corrosion testing are insufficient sample size, irrelevant test soils, nonrepresentative ductile‐iron material, and omission of surface roughness measurements of the unexposed pipe. Confidence‐limit calculations and regression analysis are discussed.
