标准范围

ISO 28580:2009规定了在受控实验室条件下测量主要用于乘用车、卡车和公共汽车的新型充气轮胎滚动阻力的方法。ISO 28580:2009中不包括仅供临时使用的轮胎。ISO 28580:2009包括一种将测量结果关联起来的方法，以便进行实验室间比较。使用该方法测量轮胎时，可以比较在垂直于滚筒外表面的位置和稳态条件下自由向前滚动的新试验轮胎的滚动阻力。在测量轮胎滚动阻力时，有必要在存在更大力的情况下测量较小的力。因此，必须使用适当精度的设备和仪器。

ISO 28580:2009 specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on passenger cars, trucks and buses. Tyres intended for temporary use only are not included in ISO 28580:2009.ISO 28580:2009 includes a method for correlating measurement results to allow inter-laboratory comparisons. Measurement of tyres using this method enables comparisons to be made between the rolling resistance of new test tyres when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions.In measuring tyre rolling resistance, it is necessary to measure small forces in the presence of much larger forces. It is, therefore, essential that equipment and instrumentation of appropriate accuracy be used.
