Ethanol Testing & Certification

We conduct all of the tests required for the ASTM D4806 specification for ethanol used for fuel blending.  Our customers include ethanol producers, rail terminals and fuel terminals.

Ethanol is widely used for gasoline fuel blending in the US, Brazil, and Europe, and its use is expected to increase as a result of clean air regulations. Common gasoline-ethanol fuel blends include E10 (containing 10% ethanol) and E85 (containing 85% ethanol). Most motor vehicles today run using E10, and an increasing number of cars and light trucks are designed to be flexible-fuel vehicles, using ethanol-blend fuels up to E85.

The purity of ethanol going into fuel blending is critically important if the finished blend is going to meet specifications.  The most common issues with blending ethanol are high water content and low pH (acidity).  Other potential issues include non-volatile residue (gum), high methanol content and contamination with sulfates and chlorides.

The following is a list of the ethanol-related tests that we perform.  For additional information about the test method, click on the method number.
