UN Regulation No. 93 (Front underrun protection)
44. Recalling the purpose of GRSG-115-25 presented at the previous GRSG session, the expert from EC proposed to update the provisions on frontal underrun protection to be approved as integrated part of the vehicle, and in particular, to allow more a rounded shape of cabs for better aerodynamic performance (GRSG-116-41). The proposal received general support from GRSG. The expert from OICA offered to send her contributions to the expert from EC. GRSG agreed to resume consideration of this subject at the next session on the basis of an official document.
GRSG-115-25 | UN R93: Proposal for amendments
Document Title: UN R93: Proposal for amendments
|
Document Reference Number: GRSG-115-25
|
Description: 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.

Working Party on General Safety | Session 115 | 9-12
Oct 2018
66. The expert from EC introduced GRSG-115-25 to update the provisions on frontal underrun protection approved as integrated part of the vehicle, in particular, to allow for a more rounded shape of the cab for a better aerodynamic performance. The proposal received a number of comments and a study reservation by the expert from the Netherlands.
67. The expert from EC volunteered to review his proposal taking into account the comments received. GRSG agreed to resume consideration of this subject at its next session in April 2019 on the basis of an official document.

GRSG-116-41 | UN R93: Proposal for amendments
Document Title: UN R93: Proposal for amendments
|
Document Reference Number: GRSG-116-41
|
Description: 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.
