8.5. General approach to measurement uncertainties in UN Regulations

At its previous session, the World Forum noted that the GRBP Informal Working Group on Measurement Uncertainties (IWG MU) had developed a general approach how to handle measurement uncertainties which could apply not only to UN Regulations under GRBP, but also to other UN Regulations (ECE/TRANS/WP.29/1164, para. 62). The Chair of IWG MU will brief WP.29 on the concept.
