ISO 10307-2:2009规定了两个程序——A（热）和B（化学）——用于加速剩余燃油老化。当与ISO 10307-1中规定的热过滤方法相结合时，这些程序允许预测燃料油在储存和处理过程中受沉降影响的稳定性。

ISO 10307-2:2009 specifies two procedures — A (thermal) and B (chemical) — for the accelerated ageing of residual fuel oils. When combined with the hot filtration method specified in ISO 10307-1, these procedures permit the prediction of fuel oil stability, as affected by sedimentation, during storage and handling of the fuel oils.
