ISO 10844:2021

This document specifies the essential characteristics of a test track surface intended to be used for measuring rolling sound emission of vehicles and their tyres. The surface design given in this document —    produces consistent levels of tyre or road sound emission under a wide range of operating conditions including those appropriate to vehicle sound testing, —    minimizes inter-site variation, —    limits absorption of the vehicle sound sources, and —    is consistent with road-building practice.
