Biodiesel Testing & Certification

We perform biodiesel quality testing on a wide range of biodiesel blends. We also perform testing to determine the biodiesel content in regular diesel fuel. We can conduct a full set of tests on biodiesel according to the ASTM D6751 and ASTM D7467 specifications.

Biodiesel is becoming an increasingly important fuel. Biodiesel is made from a variety of materials, including soybean oil, recycled cooking oil, and animal fats. It is blended with diesel to make automotive fuel. Biodiesel blends are labeled BX or BXX, X being the percentage of biodiesel in the mixture. Most major diesel fuel retailers are now selling B5 biodiesel blends. Industry standards allow the use of up to 5 percent biodiesel without special labeling on the fuel pump.  Tax incentives currently encourage blending, so most diesel currently for sale is in fact B5.  Vehicle owners and operators should check their owner’s manual or consult their auto manufacturer before using biodiesel, since using the wrong grade of fuel can cause engine damage.

Biodiesel is a biodegradable fuel that produces less air pollution than petroleum-based diesel. Biodiesel is also non-toxic and safer to handle than most conventional fuels. However, biodiesel frequently has problems with low-temperature fluidity (e.g., freezing/gelling), so high percentage biodiesel blends are usually not suitable for use in low temperatures.  The most common issues with biodiesel are related to low-temperature properties and oxidation stability.  As biodiesel oxidizes it can produce solid particles that can plug filters and fuel injectors.
