Abstract: Oxidation stability is one of the most important properties of biodiesel blend fuels. Various standard test methods to evaluate the oxidation stability of biodiesel blend fuels were presented and compared in this paper. It is indicated that the accele-rated oxidation method of distillate fuel oil (ASTM D 2274 or SH/T 0175) and oil stability index (OSI) method (EN 14112) were two widely accepted standard methods which might be specified in a variety of biodiesel blend fuel specifications. Other standard methods such as distillate fuel storage at 43℃ method (SH/T 0690 or ASTM D 4625), high temperature stability method (ASTM D 6468), JFTOT method(GB/T 9169 or ASTM D 3241)and gasoline induction period method (GB/T 8018 or ASTM D 525)could also be useful methods to study the oxidation stability of biodiesel blend fuels. Suggestions are given to specify the oxidation stability of the coming draft national specifications of B5,B10 and B20 as well.

Key words: biodiesel blend fuels, oxidation stability, test method
