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 … Read more
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
Based on ASTM E 203. The determination is carried out using the Karl-Fischer Titrator. The result is important as biodiesel is hygroscopic. Main Research: Harrison Lau Lik Nang
Based on ASTM D 2500. The cloud point is the temperature of a liquid specimen at which the smallest observable cluster of wax crystals first appears upon cooling under prescribed conditions. Main Research: Yung Chee Liang
Based on ASTM D 97. The pour point is the lowest temperature at which movement of the test specimen is observed under the prescribed conditions of the test. Main Research: Yung Chee Liang
Based on EN 116. The CFPP is the highest temperature at which a given volume of fuel fails to pass through a standard filtration device in a specific time, when cooled under standard conditions. Main Research: Yung Chee Liang
The determination is by titrimetry based on EN 14104. The acid value is expressed as the amount (in milligrammes) of potassium hydroxide required to neutralize one gramme of the biodiesel (mg KOH g-1). Main Research: Puah Chiew Wei
Based on EN 14103, and carried out using gas chromatography with internal calibration (methyl heptadecanoate). The methyl ester peaks in the analysis range from myristic acid (C14:0) to nervonic acid (C24:1). The result is expressed as the mass fraction in percent. Main Research: Puah Chiew Wei
Based on EN 14105. The determination is by gas chromatography with internal calibration. The contents are expressed in percentages (w/w), to the nearest 0.01%. Main Research: Harrison Lau Lik Nang
