FMVSS 301 Test Standard for Fuel System Integrity

FMVSS 301 Barrier Impact

The FMVSS 301 standard applies to passenger cars and MPVs, trucks and buses using fuel with a boiling point above 0 °C. In any stationary or mobile barrier crash test, fuel spillage should not exceed 28 g until the vehicle stops moving without impact, and a total of 5 g within the 142 minute period following the cessation of movement. For the next 25 minutes, the fuel pour in any 1 minute interval shall not exceed 28 g.

FMVSS 301 Rolling

This standard applies to passenger cars and MPVs, trucks and buses using fuel with a boiling point above 0°C. In any rollover test, the fuel spill from the start of the rollover should not exceed 142 g total in the first. 90 minute test at each consecutive 5° increment. For the remaining test period, the fuel pour at any 90 minute interval shall not exceed 1 g at each successive 28° increment.

The test configuration specified by the National Highway Traffic Safety Administration (NHTSA) is shown in figure 1. The MDB is retracted to its longitudinal axis at a crab angle of 27. This configuration aims to simulate a striking general vehicle traveling at 48,4 km/h, perpendicular to the side of the crashed vehicle traveling at 24,2 km/h. The crab-angle configuration allows simulation of a two-vehicle side impact, both in motion, using a simplified test method where only one vehicle is in motion.
