Evaluation of Fire Resistance Test Proposal for Vehicle Safety: July 2011 Study

This report presents the findings and evaluations concerning the proposal of a fire resistance test conducted by the Korea Transportation Safety Authority (TS) and the Korea Automobile Testing and Research Institute (KATRI) from July 5 to 7, 2011. The study aimed to assess the feasibility of the proposed test configurations and conditions, measure temperature profiles, and analyze test results. The goal is to ensure that vehicles can withstand external fire threats, providing adequate evacuation time for passengers while preventing explosions, especially in scenarios like fuel spills.

  11. Comments 2/2 4. Comments for ‘Fire resistance test’ • Rationale of proposal : • Simulates exposure of [RESS] to fire from the outside of the vehicle due to e.g. a fuel spill from a vehicle (either the vehicle itself or a nearby vehicle). This situation should leave the driver and passengers with enough time to evacuate and no explosion should occur in a later stage. 11/11
