Describes the essential characteristics of a test surface intended to be used for measuring vehicle and tyre or road noise emissions.

This International Standard specifies the essential characteristics of a test surface intended to be used for measuring vehicle and tyre or road noise emissions.

The surface design given in this International Standard

• 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,

• provides minor absorption of the vehicle sound sources, and

• is consistent with road-building practice.

NOTE For the purposes of this International Standard, the terms noise and sound are used interchangeably.
