This Technical Report explains the requirements and test methods for marketed and delivered ethanol (E85) automotive fuel according to EN 15293. It provides background information on the final text of the draft European standard and gives guidance and explanations to the producers, blenders, marketers and users of ethanol (E85) automotive fuel.

NOTE 2  For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction, µ, and the volume fraction, φ, respectively.
