AGQM's 10th No-harm Test Round on oxidation stabilizers underway

By AGQM | December 29, 2015

The German biodiesel quality management association AGQM started its 10th round robin test for oxidation stabilizers for biodiesel and, for the first time, also for bio heating oil. As experiences from the past show no-harm testing is essential for safe additization.

Today petroleum based diesel fuel is blended with up to 7 percent biodiesel on the basis of EN 590, the European Standard for diesel. Oxidation stabilizers for the biodiesel component are strongly recommended, which is why producers of commercial biodiesel already admix antioxidants in almost all cases. Possible negative interaction of the additives with diesel fuel and its additives are ruled out by AGQM’s sophisticated no-harm tests.

This year for the first time AGQM offers a test program for oxidation stabilizers for biodiesel intended for the use in heating oil, as a reaction to the increasing demand for bio heating oil. For this application also safe handling and compatibility of the additives must be guaranteed at all times.

After nine test runs with 64 additives—44 tested successfully—it is obvious that no-harm testing is essential for safe additization. The no-harm list with all certified oxidation stabilizers for biodiesel is published on AGQM’s homepage.
