| GRBP | Session 77 | 7-10 Feb 2023 |
6. The Chair of IWG MU reported on their activities (GRBP-77-10-Rev.1) and presented amendments to the document of reference on measurement uncertainties (GRBP-77-07 and GRBP-77-08). GRBP adopted the amendments and requested the secretariat to publish the revised document of reference on the GRBP website. 7. The expert from IWG MU introduced a proposal that aimed to amend UN Regulation No. 51 with tables showing the measurement uncertainties when performing type approval, conformity of production (COP) or field testing (e.g. market surveillance) (GRBP-77-09). Some GRBP experts suggested that these tables be included not in the UN Regulation, but in another document, for example, the above document of reference. Following an exchange of views, GRBP decided to revert to this issue at the next session. |
