5. The experts of IWG MU introduced a new draft document for reference on measurement uncertainties which addressed UN Regulations Nos. 51 and 117 as a first step (GRBP-78-07). The experts from France and the United Kingdom posed questions, while the experts from Germany and the Netherlands pointed out a large test track uncertainty. The Chair invited IWG MU to liaise with the above experts with the aim to prepare a revised document for the next session. |
