Discussion paper on the proposal to revise the scope of UN R29 to cover N3 vehicles and N2 vehicles with a gross vehicle mass exceeding 7.5t with a separate driver’s cab and to N1 vehicles and N2 vehicles with a gross vehicle mass not exceeding 7.5t with regard to the protection of the occupants of the cab.
28. The expert from Sweden introduced ECE/TRANS/WP.29/GRSP/2013/9, containing an alternative to the proposal for expanding the scope of the UN Regulation to all N categories of vehicles, as suggested by the expert from the Russian Federation (ECE/TRANS/WP.29/GRSP/2012/19). The expert from OICA introduced GRSP-53-02, providing a layout of a possible testing configuration for each configuration of N categories. He stated that these different configurations make unfeasible the application of all tests to all N types. The expert from the Russian Federation introduced GRSP-53-03 to stress that all vehicle of category N (even N1 category of vehicle) should be covered by UN Regulation No. 29 and proposed to assess with GRSP experts which of the test configurations (A, B and C) of the UN Regulation should be applied to each N vehicle category.
29. Finally, GRSP agreed to resume consideration on this subject at its December 2013 session on the basis of a possible joint proposal prepared by the experts from the Russian Federation, Sweden and OICA.
