3 Crash Management System 17
Fig. 3-17: Test configuration (ECE-R 93)
The defined forces are applied on the prescribed test points. The force courses are shown in
Fig. 3-18. The red curves represent the force course on the left hand side and the blue ones
those on the right hand side. The left graph shows the force curves for the outer test point
and the right graph shows the same for the inner test points. The fact that the force level is at
the required force level during the prescribed time period shows that the underrun protection
device is able to withstand the defined forces.
