Germany's biodiesel quality organization AGQM (Arbeitsgemeinschaft Qualitätsmanagement Biodiesel eV) has published the results of its second round of tests of oxidation stabilizers for biodiesel blends.

In making the announcement of the new additions to the "no-harm list", AGQM pointed out that the norm for DIN 51628 "urgently recommends oxidation stabilizers as biodiesel component in B7 fuel" and is increasingly part of contract specifications in the industry.

AGQM recently completed a battery of tests on submitted additives to ensure that the chemical or technical characteristics of the fuels are not impaired, that no inadmissible interactions with other fuel components occur and that a comprehensible description of application is available. In addition, tests of the relative efficiency were also performed.

The "no-harm" list now contains information on 20 tested products from 14 suppliers in six countries. The list is available at the AGQM Web site here. AGQM has decided to start a third test period with the test results expected to be available in March 2010.
