Safety
The vehicle equipped with the roof bars is placed on a mobile test bench. A  box with the corresponding load is placed on the roof bars and connected to a traction system.

Duration: 30 minutes
Standards in force:
NFR 18903-1
ISO 11154-1
DIN 703

The roof bar test consists of three quasi-static tests.
1.1. F.A.
  • Vertical traction on front bar. The rear bar will be tested only if the attachment system is different from the system used for the front bar.
  • Traction force: 2500 Newtons + ½ half the acceptable load on the bars for 10 minutes. e.g. if the maximum acceptable load is 75 kg then the vertical traction will be 2500 N + 32.5kg*G= 2500 + 325 = 2825 N. G represents the acceleration.
  • This test simulates a situation of strong catching in the wind.
  • The test must not show any detachment of the bar.
1.2. F.L.
  • Longitudinal force in the longitudinal direction of the vehicle.
  • Tensile stress: 40 times the maximum acceptable load, instantaneously.
  • This test simulates an emergency braking or rear impact situation.
  • The test must not show any detachment of the bar or any movement of the bar by more than 50 mm.
1.3. F.L.Q.
  • Longitudinal traction at 20° with respect to the longitudinal direction of the vehicle
  • Tensile stress: 40 times the maximum acceptable load, instantaneously.
  • This test simulates a situation of taking a bend at high speed.
The test must not show any detachment of the bar or any movement of the bar by more than 50 mm.
