20. The expert from OICA introduced ECE/TRANS/WP.29/GRSP/2013/19, proposing a test configuration (A, B and C) for each N vehicle category. GRSP adopted ECE/TRANS/WP.29/GRSP/2013/19 not amended and requested the secretariat to submit it to WP.29 and AC.1, for consideration and vote at their June 2014 sessions as draft Supplement 2 to the 03 series of amendments to the UN Regulation.

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.
