Content DescriptionThis 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. About ISOISO, the International Organization for Standardization, brings global experts together to agree on the best way of doing things – for anything from making a product to managing a process. As one of the oldest non-governmental international organizations, ISO has enabled trade and cooperation between people and companies all over the world since 1946. The International Standards published by ISO serve to make lives easier, safer and better. |
