ISO 10521-2:2006规定了在底盘测功机上设置目标道路载荷的方法，以便进行后续试验，例如油耗试验或废气排放测量试验。 底盘测功机上的道路载荷设置方法取决于道路载荷测量方法，如滑行法、扭矩计法或风洞和底盘测功机法。ISO 10521-2:2006详细说明了道路车辆底盘测功机设置程序的方法- 载荷值，通过ISO 10521-1:2006中规定的各种测量方法获得。 ISO 10521-2:2006适用于底盘测功机，该测功机可将道路载荷设定为至少三个速度点，并适用于ISO 3833:1977中定义的车辆总质量不超过3500 kg的机动车。

ISO 10521-2:2006 specifies methods of setting the target road load on chassis dynamometers for the purpose of a subsequent test, for example the fuel consumption test or the exhaust-emission measurement test. The road-load setting method on chassis dynamometers depends on the road-load measurement method, such as the coastdown method, the torquemeter method or the wind-tunnel and chassis-dynamometer method. ISO 10521-2:2006 gives detailed instructions on the methods of the chassis-dynamometer setting procedure for road-load value, obtained by the various measurement methods specified in ISO 10521-1:2006. ISO 10521-2:2006 is applicable to chassis dynamometers that can set road load at a minimum of three speed points, and to motor vehicles as defined in ISO 3833:1977 up to a gross vehicle mass of 3 500 kg.
