Draft proposal for an informal document to amend UN R169 to facilitate approvals of 8-12 ton vehicles derived from M₁/N₁ vehicles via compliance with provisions of UN R160.

Proposal concerning “detected objects” and data element precision for the ADS regulation provisions on DSSAD.

Proposal concerning “detected objects” and data element precision.

Proposal to clearly exempt vehicle types without a coupling system to charge the REESS in order to avoid administrative and technical burdens on vehicles outside the intended scope of the 06 series amendments.

Responses to the EPPR questionnaire on legislative gaps in the transposition of GTR 2 into UN R40.

Discussion paper from the EVE ad hoc group on System Power to allow for the measurement of power of battery propulsion units.

Report to WP.1 (UN Global Forum for Traffic Safety).

German position paper arguing for greater objectivity and clarity over the use of the proposed “M+S”, “M.S”, “M&S”, and “Alpine” symbol with regard to “snow tyres” and “snow tyres for use in severe snow conditions”.

Draft proposal to incorporate provisions for audible signals when a vehicle is in reverse gear, including specifications relative to ambient noise levels.

Correction to paragraph 6.2.2. “Sound level limits” to add a reference specifically to paragraph 3.1 of Annex 3 in order to ensure interpretation of the sound limit values as application only “noise in motion” and not to “stationary noise”. This aligns the 02 and 03 series texts.

Proposal for a new working group to develop harmonized technical specifications, test procedures and performance requirements for audible warning systems that signal when a category M₃, N₂, or N₃ vehicle is moving in reverse gear.

Discussion of motorcycle and related vehicle noise issues, especially related to aftermarket modification (non-original replacement exhaust silencer systems (NORESS)).

German authorities have carried out a study to assess the possibility for measuring UN R41.04-approved L category vehicles using typical “roadside check” equipment. The study found that such equipment provides a “lite” version of the UN 41.04 procedures that is useful in evaluating real-world performance. Germany intends to pursue a national “pass-by lite” test directive for UN R41-approved motorbikes and for non-original replacement exhaust silencer systems (NORESS) roadside and periodic technical inspections.

Proposal to introduce provisions for non-original replacement silencing systems (NORESS, independent aftermarket muffler systems) with multiple, manually or electronically adjustable, rider-selectable operating modes or variable geometries (NORESS with “flexibilities”). These "flexibilities enable the replacement systems to meet the requirements of Annex 3 (i.e., during testing) while producing much higher noise (sound pressure) outside the Annex 3 conditions. This amendment would require such NORESS to meet the ASEP requirements of UN R9 and UN R41. The amendment further introduces language taken from UN R51. In effect, NORESS with flexibilities performance under normal driving conditions would not be permitted to deviate from its performance under testing.

Presentation in support of Germany’s proposal for amendments to UN R92 on non-original replacement exhaust silencing systems.

Proposal to address non-negligible differences in sound performance in cases where COP tests are carried out under conditions that differ from those used for the granting of the type approval. The proposal introduces conditions, procedures, and corrections to be applied to L_urban to account for the difference in test conditions.
