Proposal for improvements to the draft Revision 2 to GRBP/2022/9.
Draft proposal to introduce a new Annex 10 (“Estimation of the calculation of the expanded measurement uncertainties for sound measurements of Annex 3 for vehicles of category M and N”) to provide tables showing the measurement uncertainties when performing type-approval, Conformity of Production, and/or field testing (e.g. market surveillance). This work is associated with the “Document for Reference” which describes a general approach to estimating measurement uncertainties (GRBP/2022/9/Rev.1 pending consideration of Revision 2).
Proposal to improve evacuation times of M2 and M3 vehicles, including new provisions for devices to break window glass.
Proposal to introduce provisions for ice grip tyres, clarify provisions on Conformity of Production, sample submissions, and testing methods, and to make editorial corrections and improvements.
Proposal to correct some references, which need to be updated as a consequence of document WP.29/2020/70, adopted at the June 2020 WP.29 session, notably
Proposal to amend the extended mobility tyre (EMT) symbol following the detection of dimensional inconsistencies within the International Organization for Standardization Working Group (ISO) TC31/SC3/WG19, where the dimension “0,33h” was judged wrong and constituting an unnecessary over constraint and to amend the inflation value to be used for the tyre conditioning when assessing the “flat tyre running mode” of “run flat tyres” and of “extended mobility tyres”.
Proposal to clarify the scope and application of the regulation.
