UN R93: Proposal for amendments
|
|
Reference Number: GRSG/2019/19
|
|
Proposal to update Part III of UN R93 to enable approval of truck cabs where the front underrun protection is integrated in the motor vehicle (in order to improve aerodynamic performance). This proposal would define the forward reference point as being the same transverse location where the force is applied. This results in FUPs where (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. The proposal includes transitional provisions from 1 September 2020.
