GRSG agreed to review a proposal by EC to update the provisions on frontal underrun protection which are approved as an integrated part of the vehicle, in particular, to allow for a more rounded shape of the cab for a better aerodynamic performance, if available.

UN R93: Proposal for amendments
|
|
Reference Number: GRSG-115-25
|
|
In anticipation of improvements to truck-cab aerodynamics, this proposal would update Part III of UN R93 where the front under-run protection is integrated in the motor vehicle by defining the forward reference point as the same transverse location where the force is applied. This results in FUPs that, in the case of cab fronts that are curved, at least 400 mm must be maintained along the front contour of the cab, instead of the foremost point.
