Proposal to clarify that it is not necessary to require an ISO 10844 asphalt track surface in cases where the vehicle is at a standstill provided that the surface is dense and without substantial absorption characteristics.
11. The expert from Poland proposed to allow surfaces other than ISO 10844 for measurements in standstill condition (GRBP-71-28-Rev.1). GRBP adopted the proposal, as contained in Annex V, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2020 sessions as a draft Supplement 2 to the 01 series of amendments to UN Regulation No. 138.
