มอก. 1666-2541

Scope (English)

This standard specifies the materials design, construction and properties of a test surface in order to minimize intersite variation in vehicle noise measurements. In particular, the surface design given in this international standard will - produce ralatively low levels of tyre/road noise under a wide range of operating conditions including those appropriate to vehicle noise testing; - provide negligible absorption of noise from the vehicle s power unit and related sources; - be consistent with general road-building practice.
