Based on ASTM D 445. The kinematic viscosity is the time taken by a volume of sample (liquid form) to flow under gravity through a calibrated glass capillary viscometer. The unit is in mm2 s-1. Main Research: Yung Chee Liang 

Based on ASTM D 93 and using a PenskyMartens closed cup tester. The flash point is the lowest temperature at which an ignition source ignites the vapours from the sample under the specified conditions of the test. Main Research: Yung Chee Liang

Based on ISO 10370. EN 14214 requires the test to be carried out on a 10% distillation residue of the sample while ASTM D 6751 requires 100% sample without prior distillation. The carbon residue value approximates the tendency of biodiesel to form deposits. The carbon residue is the residual material after evaporation and pyrolysis of […]

Based on EN 14112 and using a 743 Rancimat instrument. It is an accelerated oxidation test with the oxidative stability expressed in hours. Main Research: Yung Chee Liang 

Based on ASTM D 1796 (1997) and using a centrifuge. This result is important because high water and sediment contents can corrode and block the fuel filters and injectors. Main Research: Harrison Lau Lik Nang
