3. TEST PLANS The following are high level specifications for the planned tests. The contractor conducting each test will develop a detailed test plan as an early contract deliverable. 3.1 Coefficient of Friction-(Post derailment tank car kinetic energy dissipation) The contractor will perform a full-scale test to determine the coefficient of sliding friction between a tank car and the ground. The contractor will perform testing with the tank car on its side. The contractor will repeat the test on a variety of different ground conditions including those representing wet, dry and frozen agricultural land, and ballast. Plan for testing at TTCI [Transportation Technology Center, Inc.]. Will pull an empty and partially loaded tank car across the ground with a bulldozer or equivalent. 3.2 DOT-117 Puncture Resistance The contractor will conduct full-scale impact tests to provide data to validate the computer model of a DOT-117 tank car. The tests will be conducted against the crash wall at FRAâs Transportation Technology Center in Pueblo, Colorado. The contractor may perform two tests: one that does not cause puncture and one that does. Test completeâ¦.preliminary results appear to validate simulations.
