Proposal to introduce requirements for non-original replacement exhaust silencing systems with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). This is a consolidated version of the amended regulation with the changes marked in bold and strikethrough text.

Proposal to address comments on the adopted Supplement 4:

1. align the flowchart in the appendix to Annex 3, Figure 3c with the amendment to paragraph 3.1.2.1.4.1 (c) of Supplement 3 to the 03 series
2. amend Appendix to Annex 3, Table 1 to limit to pure electric vehicles the options to either use mechanical or electronic devices to control the gear shift or take measures to avoid accelerations greater than 2.0 m/s² (GRB/2018/2 and GRB-67-17)
3. under Annex 7, paragraph 5.2., align the principle of testing between automatic and manual transmission having more than 5 gears.

In informal document GRB-66-12, Germany suggested making ASEP testing mandatory under UN R41.
This proposal from IMMA amends UN R41 towards the application of ASEP test procedures.

Proposal for amendments to introduce ASEP requirements for L4 and L5 category vehicles with PMR > 50 W/kg.

Proposal to introduce a definition for “Extended Mobility Tyre” based on a new “minimum requirement” performance test procedure with the relevant pictogram to be used to properly distinguish such tyres. This document will be handled by GRB during its 68th session and is referenced under GRVA due to the “conversion” of GRRF.

Proposal to amend UN R64 in line with the introduction of the “extended mobility tyre” into UN R30 (see document GRVA/2018/6). This document will be handled by GRB during its 68th session and is referenced under GRVA due to the “conversion” of GRRF.

Proposal to

1. modify the scope with regard to Category S and R agricultural vehicles,
2. modify the paragraph numbering (and related footnotes) to improve text clarity,
3. to correct an error in Annex 5 Table 7 where “35×16” should read “36×16”,
4. amend Annex 7 Part E to address variations of load-carrying capacity for tyres for construction applications (industrial tractors or skid-steers / mini-loaders) with speed category symbol “D”.
