proposed a quick test, which if performed
just after production, could predict the storage stability of the
biodiesel after 12 months. They conducted the experiments (ASTM
D4625) on 8 biodiesel samples at 80°C for 24 h to show the
accelerated storage behavior. It was found that the modified
Rancimat test, showed good correlation with long term storage
tests in terms of repeatability and significance. It was also found
that the sample that had lowest long term storage stability under
actual conditions wasfirst to degrade during the accelerated tests
