9. The expert from the Informal Working Group on Measurement Uncertainties (IWG MU) presented a revised document for reference (GRBP-80-07-Rev.1) replacing ECE/TRANS/WP.29/GRBP/2024/8 considered at the previous session. The experts from the Netherlands, Switzerland, United Kingdom and EC expressed concerns over possible misinterpretation of the purpose and content of the document, in particular the suggested 3.5 dB(A) margin and the last sentence in paragraph 1.1.1. In the absence of a consensus, the Chair proposed to keep the document on the agenda of the next session as a working document. 9.
