Document GRB-59-09
28 January 2014

Presentation in support of the proposal for additional vehicle categories and sound emission level requirements under UN R51. A “Flat Front Light N1 Vehicle” is defined as:

  • GVM ≤ 2.5 ton
  • PMR (power to mass ratio) of GVM ≤ 35kW/t
  • Engine capacity ≤ 660cc
  • d value<1,100mm
. Japan believes higher noise thresholds are warranted for these mini-trucks.

3. (a) Development

9. GRB resumed consideration of the limit values for certain vehicle categories on the basis of a presentation by the expert from Japan (GRB-59-09) on flat front light vehicles of category N1. The experts from France, Germany, Italy and OICA supported GRB-59-09. The expert from EC stated that a common EU position on this issue, as well as on M3 buses, was expected at the beginning of 2014.

10. Thus, GRB recalled GRB-58-08, GRB-58-09 and GRB-58-10 tabled by the expert from China in which he suggested higher limit values for vehicles of a specific category on the Chinese market. Referring to the above proposal by Japan, GRB invited the expert from China to explain and further justify his proposal in a similar way, possibly at the next sessions of the IWG on UN Regulation No. 51 and UN Regulation No. 59 in March and May 2014. GRB agreed to refer GRB-59-04-Rev.1 to the IWG incorporating all the changes agreed during the session, including GRB-59-09. GRB also agreed to resume discussion on the 03 series of amendments at its September 2014 session on the basis of an official proposal submitted by the IWG.
