ISO 10521-1:2006规定了确定道路车辆道路载荷的方法，用于后续试验，例如，油耗试验或废气排放测量。这确定了在参考大气条件下，在水平道路上行驶的车辆的道路载荷。可通过滑行法、扭矩计法或风洞/底盘测功机法实现。 ISO 10521-1:2006适用于ISO 3833:1977中定义的车辆总质量不超过3500 kg的机动车。

ISO 10521-1:2006 specifies methods of determining the road load of road vehicles for subsequent test purposes, for example, fuel consumption tests or exhaust emission measurements. This determines the road load of a vehicle running on a level road under reference atmospheric conditions. It is achieved by either the coastdown method, the torquemeter method or the wind-tunnel/chassis-dynamometer method. ISO 10521-1:2006 is applicable to motor vehicles, as defined in ISO 3833:1977, up to a gross vehicle mass of 3 500 kg.
