GRBP will recall that, at its previous session, the expert from the International Motorcycle Manufacturers Association (IMMA) presented interpretation documents on the application of the Real Driving Additional Sound Emission Provisions (RD-ASEP) in the 05 series of amendments to UN Regulation No. 41. He explained that the objective of his documents was to avoid an excessive number of test runs through the proposed interpretation of the number of test points and the applicable test speed. GRBP decided to revert to this topic at this session.

GRBP will be informed about the activities of the Informal Working Group on Real Driving – Additional Sound Emission Provisions (IWG RD – ASEP).

GRBP will recall that, at its previous session, the expert from the Informal Working Group on Measurement Uncertainties (IWG MU) presented a draft document for reference. During an in-depth discussion, several experts from contracting parties expressed concerns that the document could be misinterpreted as being legally binding and modifying the established sound limits in UN Regulation No. 51. In the absence of consensus, GRBP postponed the discussion to the present session.

GRBP will recall the adopted guidelines on antitampering provisions for Non-Original Replacement Exhaust Systems (NORESS) and will consider a proposal of a special interest group that integrates the guidelines into the legal text of UN Regulation No. 92.

GRBP is invited to consider corrections to the 04 series of amendments to UN Regulation No. 117 submitted by the experts from ETRTO.

GRBP is invited to address a revised proposal by the expert from the Russian Federation that clarifies certain provisions.

GRBP may expect a progress report of the Task Force on Tyre Abrasion (TF TA) and will consider its amendment proposals, if any.

GRBP will take note that, at the June 2024 session of WP.29, the representative of the Russian Federation presented WP.29-193-10 on the establishment of limits for emissions of harmful substances from tyres and suggested that TF TA should explore the possibility of introducing limits for polycyclic aromatic hydrocarbons in tyre production compounds. WP.29 recalled several precedents in UN Regulations which set out restrictions on the harmful substances, e.g. asbestos, in vehicle parts, and invited GRBP to look into the issue and to report back to WP.29.

GRBP will consider amendment proposals, if any, to other UN Regulations on tyres.

GRBP will continue the exchange of views on developing national or regional legislation and international requirements on noise levels. In particular, GRBP will be briefed on the activities of the Task Force on Vehicle Sound (TF VS).

GRBP will consider new proposals, if available.

GRBP will be informed about the progress in implementing the International Whole Vehicle Type Approval (IWVTA) (UN Regulation No. 0).
