GRBP will receive a final report on the activities of the Informal Working Group on Measurement Uncertainties (IWG MU) and will consider its proposal for a document for reference.

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

GRBP/2024/8 | Measurement uncertainties when testing in UN Regulations under the purview of GRBP Proposal from the Measurement Uncertainties informal group for a Document for Reference providing a general approach on how to handle measurement uncertainties in UN Regulations (initially addressing UN Regulations Nos. 51 and 117).

GRBP-79-02 | Noise measurement uncertainties status report to GRBP

GRBP-79-11 | IWG ASEP: Status report

GRBP-79-33/Rev.1 | UN R51: Proposal for a supplement 10 to the 03 series of amendments Some corrections and clarifications concerning power definition, calibration, temperature correction and Reference sound assessment

GRBP-79-43 | UN R51: Proposal for a supplement 11 to the 03 series of amendments In introducing ASEP in Annex 7 in 2016, the scope was limited to vehicles with internal combustion engines (ICE) based on the experience of variabilities in the exhaust silencing systems. Electric driven vehicles have been exempted from ASEP. For electric driven vehicles the new UN Regulation No. 138, dealing with the reduced audibility of these vehicles, was worked out until 2017. At that moment no one expected sound enhancement systems beyond the scope and aim of UN R138. This proposal is an approach to address the concern that electric vehicles might be equipped with sound enhancement systems beyond the scope and aim of UN R138. This proposal does not require any changes to UN R138.01. This proposal is given as a supplement to enable the quickest entry into force, providing all manufacturers clear direction on the design of sound enhancement systems.
