Abstract:The Transportation Technology Center, Inc. (TTCI) used the approach developed for the National Aeronautics and Space
Association to determine the probability of detection (POD) for various nondestructive test (NDT) methods used during inspection
of railroad tank cars. The Federal Railroad Administration and TTCI, along with industry participation, have performed NDT
PODs on tank car circumferential butt welds, longitudinal fillet welds and leak test samples requiring inspection under the Code of
Federal Regulations. This report provides the quantitative results obtained during this research effort, which addresses system
safety and risk analysis during handling and transportation of railroad tank cars that carry hazardous materials.
