Item text: 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.

Agenda: 12376
