Between 1922 and 1940, the National Bureau of Standards (NBS) conducted a long-term investigation into the corrosion of bare steel and iron, pipes buried underground at 47 sites representing different soil types in the United States. Following the passage of the 2004 Pipeline Safety Improvement Act, the Department of Transportation's Office of Pipeline Safety requested that NIST review and reanalyze the data from the NBS study using modern statistical analysis tools. For this analysis, NIST compiled an updated database from the data in the publications by K. H. Logan (i.e. NBS C450, 1945), M. Romanoff (i.e. NBS C579, 1957), and others, including examination of original logbooks. NIST published a report analyzing this data with modern computer assisted statistical analysis tools (doi.org/10.6028/NIST.IR.7415) and an archival paper summarizing the findings (doi:10.6028/jres.115.026). This data is provided in this format so that others will have the best available data from this research for future analyses.
