The test pressure for low-pressure tank cars is typically in the range of 60 to 100 PSI. This range is established based on the design and operational safety standards for low-pressure tank cars, which are used to transport a variety of hazardous materials, including liquids that require a controlled pressure environment.

Low-pressure tank cars are constructed to withstand pressures above atmospheric levels but below those considered high-pressure. The specified test pressure ensures that the structural integrity of the tank is maintained under operational conditions without failure.

Understanding this range is crucial for first responders and emergency personnel, as it helps them gauge the potential pressure hazards they might face while dealing with incidents involving low-pressure tank cars.

Therefore, the selection of 60 to 100 PSI as the correct answer reflects the generally accepted standards for low-pressure tank car testing.
