ISO 13473-3:2002规定了路面工程中使用的轮廓仪的要求，以便对铺筑道路和机场表面的微观、宏观和宏观纹理特征进行有意义和准确的测量。它还包括根据其使用和总体精度对此类轮廓仪进行分类的方案。轮廓仪可以是任何操作类型。 ISO 13473-3:2002的范围不包括机加工表面的轮廓分析。此外，不包括道路不平度的轮廓分析。

ISO 13473-3:2002 specifies requirements for profilometers used in pavement engineering in order to give meaningful and accurate measurement of micro-, macro- and megatexture characteristics of paved road and airfield surfaces. It also includes schemes for the classification of such profilometers with respect to their use and overall accuracy. The profilometers may be of any operational type. The scope of ISO 13473-3:2002 does not include profile analysis of machined surfaces. Also excluded from the scope is the profile analysis of road unevenness.
