ASTM D4806 - Standard Specification for Denatured Fuel Ethanol for Blending with Gasolines for Use as Automotive Spark-Ignition Engine Fuel

We perform ethanol quality testing by Specification ASTM D4806, which covers anhydrous denatured fuel ethanol that is blended with gasoline. This specification covers nominally anhydrous denatured fuel ethanol intended for blending with unleaded or leaded gasolines for use as a spark-ignition automotive engine fuel. According to ASTM D4806, the only denaturants used for fuel ethanol shall be natural gasoline, gasoline components, or unleaded gasoline at the minimum concentration prescribed. Prohibited denaturants include methanol which does not meet the specified requirement, pyrroles, turpentine, ketones, and tars (high-molecular weight pyrolysis products of fossil or nonfossil vegetable matter).

This specification defines the standard tests used to define "acceptable" quality for E100 used for fuel blending.  All ethanol blendstocks should be tested and certified to meet this specification.
