In some cases, standard (commercial) biodiesel can be used upon IBAMA approval. However, subsequent durability testing shall be performed using reference biodiesel. ✓ Durability limits will be the maximum emission limits multiplied by the deterioration factors given in the table below: Cycle CO THC(1) NMHC(2) CH4(2) NOX NH?
