Quantitative Nondestructive Testing of Railroad Tank Cars Using the Probability of Detection Evaluation Approach

Through sponsorship by the Federal Railroad Administration (FRA) and in cooperation with tank car industry representatives, Transportation Technology Center, Incorporated (TTCI) has developed probability of detection (POD) curves for nondestructive testing (NDT) methods allowed under 49 CFR Sections 179 and 180 for use in structural integrity inspections. TTCI has also worked with FRA and industry representatives to establish baseline PODs for bubble leak and eddy current testing. As part of the same research program the Tank Requalification and Inspection Center, Tank Car Defect Library, and master gage development also continue to be developed. It is expected that through industry use of these resources, and implementation of quantified NDT processes and procedures, an increase in safety and reliability of tank car operations over revenue service track can be achieved.
