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.
