58. Upon the request of the Working Party on Noise (GRB), the expert from the Russian Federation proposed ECE/TRANS/WP.29/GRSG/2017/20 to change, in the current version of R.E.3 (ECE/TRANS/WP.29/78/Rev.6), the units for vehicle masses from tonnes to kilograms.

59. The document received the full support of GRSG. The secretariat was requested to submit ECE/TRANS/WP.29/GRSG/2017/20 to WP.29 as an amendment to R.E.3, for consideration at its March 2018 session.

53. The expert from the Russian Federation introduced GRSG-112-11 on a proposal endorsed by the Working Party on Noise (GRB) to adapt in R.E.3 the measuring units for vehicle masses from tonnes to kilograms. GRSG endorsed the proposal in principle. The secretariat suggested to also aligning in R.E.3 some sub-categories of vehicles, such as L_1A for powered cycles and L_1B for two-wheeled mopeds. The expert from EC volunteered to prepare a comparison document between the categories listed in EU Regulation No. 168/2013 and those in Revision 5 of R.E.3. GRSG noted general support and agreed to circulate GRSG-112-11 with an official symbol for consideration at its next session.

26. The expert from the Russian Federation proposed to change the measuring units for vehicle masses from tonnes to kilograms in the Consolidated Resolution on the Construction of Vehicles (R.E.3, ECE/TRANS/WP.29/78/Rev.4) (GRB-65-03-Rev.1). GRB supported the proposal and requested the secretariat to circulate it to other WP.29 Working Parties, in particular, to Working Party on General Safety (GRSG) at its April 2017 session.
