Description
The barrier capacity class is a measure of how much energy the barrier can absorb from impact. The capacity class of a barrier is determined by a number of standadized tests where vehicles of different weights hit a barrier at different speeds and angles.
- N2
- The barrier is of capacity class N2, meaning it can absorb the energy of cars up tp 1500 kg and 110 km/h at a 20 degree angle.
- H2
- The barrier is of a capacity class H2, meaning it can absord the energy of cars up to 900 kg and 100 km/h and vehicles up to 13000 kg and 70 km/h hitting the barrier at a 20 degree angle.This is a higher capacity class than N2.
- Not classified
- The barrier is not classified.
